Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the initial stage when a customer comes to consider building renovation, there are many cases where the customer's demands for renovation are not yet solidified, and it is difficult to visualize the renovation.

[0005] The present invention has been made in view of the above circumstances, and its object is to be able to propose a suitable renovation to a customer in the initial stage of building renovation.

Means for Solving the Problems

[0006] The invention according to claim 1 is, for example, as shown in FIGS. 1 to 9, a renovation proposal support device 10, There are a plurality of hierarchically classified themes 110, 111, 112, and a proposal plan storage means 107 (storage unit 107) that stores a large number of proposal plans 30 (30A, 30B) to which one or more themes are assigned from the plurality of themes 110, 111, 112, A type registration means 102 (floor plan type registration unit 102) for registering the layout type of the building 20 (plans under consideration 20, 20A~20E) that is under consideration for renovation, A non-renovation area setting means 103 (non-renovation area setting unit 103) sets a non-renovation area Nra in the layout of the building 20 under consideration in which renovations are prohibited, A theme selection receiving means 104 (theme selection receiving unit 104) that accepts theme selections in hierarchical order by customer U2, The system is characterized by comprising an extraction means 105 (extraction unit 105) that extracts proposal plans 30 in which the non-modification area Nra is common, according to the customer's hierarchical theme selection, from among a large number of proposal plans 30.

[0007] According to the invention described in claim 1, the type registration means 102 registers the type of layout of the building 20 that is under consideration for renovation, the non-renovation area setting means 103 sets a non-renovation area Nra in the layout of the building 20 under consideration in which renovation is prohibited, the theme selection receiving means 104 accepts the theme selection by customer U2 in hierarchical order, and the extraction means 105 extracts proposal plans 30 from a large number of proposal plans 30 that have a common non-renovation area Nra according to the theme selection by customer U2 in hierarchical order. As a result, proposal plans 30 that have the same layout type as the building 20 under consideration and have a common non-renovation area Nra are extracted from a large number of proposal plans 30, and further proposal plans 30 can be narrowed down according to the theme selection by the customer in hierarchical order.

[0008] The invention described in claim 2 is, for example, as shown in Figures 3 to 5 and 7 to 9, in the modification proposal support device 10 described in claim 1, The aforementioned non-renovation area Nra is a water-related area, and the non-renovation area setting means 103 is characterized in that it prohibits renovation of the non-renovation area Nra that would involve relocating piping.

[0009] According to the invention described in claim 2, the non-renovation area setting means 103 prohibits renovation of the non-renovation area Nra that involves relocating pipes, thus preventing the extraction of proposal plans that require extensive renovation of water-related areas involving pipe relocation. As a result, proposal plans 30 that do not significantly change the lifestyle can be extracted from the layout type of the building 20 under consideration, so that suitable renovation proposals can be made to customer U2 at the initial stage when customer U2 considers renovating the building.

[0010] The invention described in claim 3 is, in the modification proposal support device 10 described in claim 1, The aforementioned non-renovated area Nra is characterized by being an area that cannot be altered as defined in the prescribed management regulations for maintaining the building.

[0011] According to the invention described in claim 3, since the non-renovation area Nra is an area that cannot be altered as defined in the prescribed management regulations for maintaining the building, it is possible to extract a proposal plan 30 in which the area that cannot be altered under the management regulations for maintaining the building is not renovated. This makes it possible to propose suitable renovations to customer U2 at the initial stage when customer U2 considers renovating the building.

[0012] The invention described in claim 4 is a modification proposal support device 10 described in any one of claims 1 to 3, The aforementioned non-renovated area Nra is characterized by being any area of ​​the building 20 selected by the customer U2.

[0013] According to the invention described in claim 4, since the non-renovation area Nra is any area of ​​the building 20 selected by customer U2, a proposed plan 30 can be extracted in which any area selected by customer U2 is not renovated. This makes it possible to propose suitable renovations to customer U2 at an early stage when customer U2 is considering renovating the building.

[0014] The invention described in claim 5 is, for example, as shown in Figures 1 to 3 and 7, in the modification proposal support device 10 described in claim 4, The non-modification area setting means 103 is capable of resetting the non-modification area Nra for the proposed plan 30 extracted by the extraction means 105. The extraction means 105 is characterized by extracting proposal plans from a large number of proposal plans that share the reset non-modification area, based on the proposal plan 30 in which the non-modification area Nra has been reset, and the hierarchical theme selection by the customer U2 received by the theme selection receiving means 104.

[0015] According to the invention described in claim 5, the non-renovation area setting means 103 is capable of resetting the non-renovation area Nra for the proposed plan 30 extracted by the extraction means 105. The extraction means 105 extracts from a large number of proposed plans 30 that have the reset non-renovation area Nra in common, based on the proposed plan 30 with the reset non-renovation area Nra and the hierarchical theme selection by the customer U2 received by the theme selection receiving means 104. For example, the customer U2 can reset parts of the proposed plan 30 that they like or overlooked as non-renovation area Nra, and then extract the proposed plan 30 again while retaining those areas. This makes it possible to propose more suitable renovations to the customer U2.

[0016] The invention described in claim 6 is, for example, as shown in Figures 1 to 4, in the modification proposal support device 10 described in claim 1, The aforementioned theme selection receiving means 104 is, Save the previously received hierarchical theme selection as primary information 121 and copy it (121a), For the copy 121a of the primary information 121, further receive the hierarchical theme selection by the customer U2 and save it as secondary information 122, The extraction means 105 is characterized in that it is possible to extract the proposed plan 30 based on the primary information 121 and the secondary information 122, respectively.

[0017] According to the invention described in claim 6, the theme selection reception means 104 saves the previously received hierarchical theme selection as primary information 121 and copies it, and for the copy 121a of the primary information 121, further receives the hierarchical theme selection by the customer U2 and saves it as secondary information 122. The extraction means 105 can extract the proposed plan 30 based on the primary information 121 and the secondary information 122, respectively. Therefore, the conditions selected by the customer U2 himself / herself are saved, and the theme selection can be performed again based on those conditions. As a result, a plurality of proposed plans 30 with similar patterns can be extracted, making it easier to extract a proposed plan 30 close to the requirements of the customer U2.

[0018] The invention described in claim 7, for example, as shown in FIGS. 1 to 4, in the repair proposal support device 10 described in claim 1, The extraction means 105 is characterized in that it is possible to extract the proposed plan 30 from among the numerous proposed plans 30 stored by the proposed plan storage means 107 for each hierarchy of the plurality of themes.

[0019] According to the invention described in claim 7, since the extraction means 105 can extract the proposed plan 30 for each hierarchy of the plurality of themes, it is possible to extract a large number of proposed plans 30 by narrowing down with themes in a relatively large concept hierarchy, or to narrow down until reaching a relatively small concept hierarchy to extract a proposed plan 30 closer to the requirements of the customer U2 more precisely.

[0020] The invention according to claim 8 is, for example, as shown in FIGS. 1 to 4, in the modification proposal support apparatus 10 according to claim 1, the theme selection reception means 104 can assign a priority to each of the plurality of themes for each hierarchy, when the extraction means 105 extracts the proposal plan 30 from among a large number of the proposal plans 30, 30A, and 30B, the extraction is performed according to the assigned priority.

[0021] According to the invention of claim 8, the theme selection reception means 104 can assign a priority to each of the plurality of themes for each hierarchy, and when the extraction means 105 extracts the proposal plan 30 from among a large number of the proposal plans 30, 30A, and 30B, the extraction is performed according to the assigned priority. Therefore, the proposal plan 30 according to the theme with a high priority can be extracted. As a result, it becomes easier to extract the proposal plan 30 close to the request of the customer U2.

[0022] The invention according to claim 9 is, for example, as shown in FIGS. 7 to 9, in the modification proposal support apparatus 10 according to claim 1, a large number of the proposal plans 30 include a type of proposal plan 30 showing the layout of the entire building and a type of proposal plan for modifying a part of the building.

[0023] According to the invention of claim 9, since a large number of the proposal plans 30 include a type of proposal plan 30 showing the layout of the entire building and a type of proposal plan for modifying a part of the building, the proposal plan 30 showing the layout of the entire building and the type of proposal plan for modifying a part of the building can be presented to the customer U2. As a result, at the initial stage when the customer U2 comes to consider the modification of the building, a suitable modification proposal can be made to the customer U2.

[0024] The invention according to claim 10 is, for example, as shown in FIGS. 1 to 9, a modification proposal support system, The modification proposal support device 10 described in claim 1 and the first user terminal 1 used by the proposer U1 (person in charge U1) who makes a modification proposal to the customer U2 are connected in a manner that enables communication. The aforementioned renovation proposal support device 10 further includes a plan transmission means 106 (plan transmission unit 106) that transmits the data of the proposed plan 30 extracted by the extraction means 105 to the first user terminal 1. The first user terminal 1 is characterized in that it receives the data of the proposed plan 30 transmitted by the plan transmission means 106 and makes it available for display on the display screen.

[0025] According to the invention described in claim 10, the first user terminal 1 receives data of the proposed plan 30 transmitted by the plan transmission means 106 of the renovation proposal support device 10 and makes it displayable on the display screen. This allows the proposer U1 to discuss the renovation proposal with customer U2 while showing them the proposed plan 30 displayed on the display screen. In other words, the proposer U1 can have a face-to-face conversation with customer U2, which increases the depth of communication and makes it easier to convey the appeal of the proposed plan 30.

[0026] The invention described in claim 11 is, for example, as shown in Figures 1 to 9, in the renovation proposal support system described in claim 9, The aforementioned modification proposal support device 10 and the second user terminal 2 used by the customer U2 are connected in a way that allows communication between them. The plan transmission means 106 is capable of transmitting the data of the proposed plan 30 to the second user terminal 2. The second user terminal 2 is characterized in that it receives the data of the proposed plan 30 transmitted by the plan transmission means 106 and makes it available for display on the display screen.

[0027] According to the invention described in claim 11, the second user terminal 2 receives data of the proposed plan 30 transmitted by the plan transmission means 106 of the renovation proposal support device 10 and makes it displayable on the display screen. As a result, the proposed plan 30 extracted by the extraction means 105 can be viewed simultaneously not only on the first user terminal 1 of the proposer U1 but also on the second user terminal 2 of the customer U2. This allows the proposer U1 and the customer U2 to discuss renovation proposals remotely and without being bound by location or time. [Effects of the Invention]

[0028] According to the present invention, it is possible to propose suitable renovations to customers in the initial stages of building renovations. [Brief explanation of the drawing]

[Figure 6] This is a diagram illustrating a typical apartment building plan. [Figure 7] This diagram outlines the proposed renovations related to zoning. [Figure 8] This is a diagram showing an example of a proposed plan. [Figure 9] This is a diagram showing an example of a proposed plan. [Modes for carrying out the invention]

[0030] Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, but the technical scope of the present invention is not limited to the embodiments and illustrated examples below. Note that the directions in the embodiments and illustrated examples below are set solely for the convenience of explanation. Furthermore, in this embodiment, "renovation" of a building includes renovation, renewal, remodeling, repair, conversion to change the use of the building, etc., but does not include the added portion in the case of an extension.

[0031] Figure 1 shows an example of the network configuration of the renovation proposal support system according to this embodiment. In the example of the network configuration of the renovation proposal support system shown in Figure 1, the renovation proposal support device 10, the first user terminal 1 of the sales representative U1 (hereinafter referred to as "representative U1") of a house builder or construction company who is the proposer of the renovation proposal to customer U2, and the second user terminal 2 of customer U2 are all connected to each other via a communication network Nw. In this embodiment, customer U2 is assumed to be the owner (resident) of a condominium unit, but may also be the owner (landlord) of a rental condominium. In the case of apartments, renting is common, and customer U2 is the owner (landlord).

[0032] The renovation proposal support system of this embodiment targets individual dwelling units in so-called condominiums (apartment buildings), but it may also target individual dwelling units in so-called apartments. Alternatively, it is not limited to residential buildings such as condominiums and apartments, but may also target detached houses, shops, offices, facilities, dormitories, inns, restaurants, etc. The condominiums containing the units targeted for renovation are constructed using either steel frame, reinforced concrete, or steel-reinforced concrete construction, while the apartments are constructed using either wood, light steel frame, or prefabricated construction.

[0033] In addition, as shown in FIGS. 5 to 7, as so-called floor plan types, the "field shape type", the "corner dwelling (corner room) type", the "center-in type", and the "wide-span type" are widely known for condominiums.

[0034] The floor plan type of the field shape is formed such that the depth direction is longer than the frontage direction, and the interior is divided into a cross. Further, bedrooms 23a and 23b are located on both sides of the corridor 22b that extends straight from the entrance 22a facing the common corridor 21a. At the back, there is a LDK room 24 (living room 24a, dining room 24b, kitchen 24c), and a balcony 21b is located on the opposite side of the entrance 22a. This refers to a plan. In addition, this field-shaped plan includes a vertically long plan in which the living room 24a and the dining room 24b are arranged along the longitudinal direction of the dwelling unit, and a horizontally long plan in which the living room 24a and the dining room 24b are arranged along the balcony 21b. For the dwelling unit of the floor plan type of the field shape, since the frontage width is suppressed, it is possible to secure a large number of dwelling units in the condominium. Examples of the advantages of the field-shaped plan include the following. · By unifying with the same floor plan, the construction cost can be suppressed, and it becomes cheaper than other floor plans. · Since the plumbing layout is the same at the upper and lower floors, noise problems are less likely to occur. · Since it is sandwiched between adjacent dwelling units, it is less affected by the outside air temperature. Examples of the disadvantages of the field-shaped plan include the following. · Compared with the corner dwelling, the lighting area is smaller, and the entrance is likely to be dark. · The windows on the side of the common corridor are difficult to open and close, so it is dark and prone to moisture accumulation. · The living rooms do not feel spacious compared to the floor area. · Since the plumbing is compact, the flow lines are likely to cross.

[0035] To explain this type of grid-shaped floor plan in more detail using the study plan 20 in Figure 7 as an example, a corridor 22b extends from the entrance 22a facing the common corridor 21a toward the center of the dwelling unit, with bedrooms 23a and 23b located on both sides of the corridor 22b. Adjacent to the far end of the corridor 22b is the wet area (i.e., the unrenovated area Nra described later), which includes the kitchen 24c of the LDK room 24, the bathroom 24a, the washroom / dressing room 24b, and the toilet 25c. At the far end of the corridor 22b is the LDK room 24, which is a room where the living room 24a, dining room 24b, and kitchen 24c coexist. In this LDK room 24, there is no wall separating the living room 24a and the dining room 24b. Furthermore, in the example shown in Figure 7, the bathroom 25a and the washroom / dressing room 25b are located on one side of the corridor 22b, while the kitchen 24c and toilet 25c are located on the other side of the corridor 22b. The LDK room 24 includes a living room 24a, a dining room 24b, a kitchen 24c, and a Japanese-style room 23c that can be enclosed by sliding doors (fusuma). In other words, the Japanese-style room 23c can be made into a private room by closing the sliding doors, or it can be opened to become an extension of the LDK room 24. Furthermore, storage areas 26s, such as closets, are provided in the bedrooms 23a and 23b and the Japanese-style room 23c. Storage areas 26s are also provided in the LDK room 24.

[0036] Corner unit layouts refer to apartments located at the end (corner) of each floor, offering a plan with many windows and a sense of openness. In other words, because they are located at the end of each floor and only have one adjacent room, they can have many windows, resulting in a more open feel. Furthermore, unique features can be added to enhance their rarity and create a distinctive layout. The advantages of a corner unit layout include, for example, the following: • Because it has exterior walls on three sides, it has many windows, providing good sunlight and ventilation. • Less susceptible to noise from daily life, making it easier to maintain privacy within the same apartment building. • You can enjoy the outdoor space on the spacious balcony. • It is rare and has high resale value. Disadvantages of corner unit layouts include the following, for example: Corner rooms are more desirable, so they are more expensive. Compared to middle units, these units have lower insulation and tend to have higher utility costs. • Due to the large number of windows, furniture placement is limited.

[0037] To explain the layout of this corner unit type plan in more detail with reference to Figure 5, a corridor extends from the entrance facing the common corridor towards the center of the unit, with bedrooms located on both sides of the corridor. Adjacent to the far end of the corridor is the wet area (unrenovated area Nra), which includes the kitchen of the LDK room, the bathroom, washroom, and toilet. At the far end of the corridor is the LDK room, which is a living room, dining room, and kitchen combined. In this LDK room, there is no wall separating the living room and dining room. In addition to the living room, dining room, and kitchen, the LDK room also includes a Japanese-style room that can be enclosed by sliding doors. In the example shown in Figure 5, the wet area is located on one side of the corridor, and the Japanese-style room is located on the other side of the corridor. Storage areas such as closets are provided in the bedrooms and the Japanese-style room.

[0038] A center-in floor plan refers to a layout where the entrance is located near the center of the dwelling, with living spaces on either side. Because the entrance is centrally located, the hallway is typically short, resulting in open spaces on both sides of the living room and bedrooms. In some cases, two balconies may be included. The advantages of a center-in type plan include, for example, the following: • Public and private zones are clearly separated, making it easier to ensure privacy when guests are present. • Good ventilation and natural light. • Shorter hallways allow for larger living spaces. • It does not face a common corridor, so it offers high security. Disadvantages of a center-in type plan include the following, for example: • Compared to other types, it has higher construction costs, resulting in a higher price. • In cases where there are two units per floor and they share an elevator, etc., a reserve fund for maintenance and repair costs will be established.

[0039] To explain this type of center-in floor plan in more detail with reference to Figure 6, a corridor extends from the entrance facing the common corridor (common elevator hall) toward the center of the dwelling unit, and the corridor further extends in a crossing direction. In other words, the corridor is formed as if branching out in a T-shape from the entrance in plan view, and multiple bedrooms are arranged in a row at one end of the corridor. At the other end of the corridor, adjacent to that end, is the area around the water facilities (unrenovated area Nra), which includes the kitchen of the LDK room, the bathroom that makes up the water facilities room, the washroom and dressing room, and the toilet. At the back of the corridor is the LDK room, which is a living room, dining room, and kitchen combined. In this LDK room, there is no wall separating the living room and dining room. In addition to the living room, dining room, and kitchen, the LDK room is assumed to include a Japanese-style room that can be enclosed by sliding doors. Also, in the example shown in Figure 6, the kitchen is on one side of the corridor, and the bathroom, washroom and dressing room, and toilet are located on the other side of the corridor. Furthermore, storage areas such as closets are provided in the bedroom and Japanese-style room.

[0040] A wide-span floor plan is a type of layout that features a wide frontage on the balcony side. It is often used on plots with little depth, in buildings with ample space, or in luxury condominiums. With a wide frontage on the balcony side, it is possible to place the living room and multiple bedrooms facing the balcony. Therefore, compared to long, narrow dwellings such as a grid-like layout, it offers greater flexibility in room arrangement and a wider variety of floor plans. The advantages of a wide-span plan include, for example, the following: • It gets plenty of sunlight and has a shallow depth, so light easily reaches the entire unit, making it bright. Compared to long, narrow apartments, the hallway is shorter and the living spaces are larger. • In a layout where the living room is located in the center, it is easier for family members to communicate with each other. Disadvantages of wide-span floor plans include the following, for example: • Prices tend to be high. • The large windows make it susceptible to outside temperatures, resulting in high energy costs. • In the case of an interior corridor, common area costs will increase due to air conditioning and ventilation in the corridor.

[0041] To explain this wide-span floor plan in more detail with reference to Figure 6, a corridor (entrance hall) is provided adjacent to the entrance facing the common corridor, and bathrooms and other wet areas are located on both sides of this corridor. In addition, the LDK room is located directly opposite the entrance. In the example in Figure 6, the bathroom and washroom / dressing room are on one side of the corridor, and the toilet is on the other side of the corridor. Proceeding to the back of the corridor leads to the LDK room, which is the dining area, and further beyond the dining area is the living room, with the kitchen on one side of the dining area. On one side of the living room is a private bedroom, but this bedroom is separated from the living room only by a sliding door, and it is possible to close the sliding door to make it a private room, or open the sliding door to create an extension space for the LDK room 24. On the other side of the dining area and on the other side of the living room are private bedrooms, respectively.

[0042] The renovation proposal support device 10 is a server device that registers the floor plan type of the dwelling unit that customer U2 is considering renovating, derives a suitable renovation proposal plan for each floor plan type based on the acquired customer U2 request, and provides the derived proposal plan to at least the first user terminal 1 of the person in charge U1. In other words, by registering one of the above floor plan types, such as "rice field type," "corner dwelling unit (corner room) type," "center-in type," or "wide span type," it is possible to derive a suitable renovation proposal plan for each floor plan type. The computer comprising the modification proposal support server 10 may consist of a single computer, or it may consist of multiple computers capable of distributed or parallel processing. Furthermore, this computer may be a cloud computing system.

[0043] The first user terminal 1 is an information processing terminal device, including a PC (Personal Computer), smartphone, and tablet, used by the person in charge U1. The person in charge U1 can use the input device (keyboard, mouse, etc.) and display device (display, etc.) of the first user terminal 1 to register the floor plan type of the dwelling unit that customer U2 is considering renovating, input and send customer U2's requests for renovation, and display various information sent from the renovation proposal support server 10 to the renovation proposal support server 10. In other words, in this embodiment, the communication target of the first user terminal 1 is at least the renovation proposal support server 10, and there may be patterns in which the second user terminal 2 is not a communication target.

[0044] The first user terminal 1, although not shown in the diagram, is equipped with a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory) as its control unit. It also includes an input unit, display unit, storage unit, communication unit, etc., and is assumed to have the functions necessary for collaboration with the modification proposal support server 10 and the second user terminal 2. In this embodiment, a tablet device is used as the first user terminal 1. Therefore, the input and display units employ touch panels.

[0045] The second user terminal 2 is one of the information processing terminal devices used by customer U2, including a PC, smartphone, and tablet. Customer U2 can use the input devices (keyboard, mouse, etc.) and display devices (display, etc.) of the second user terminal 2 to send and receive various information with the first user terminal 1, and to send and receive various information with the modification proposal support server 10. In this embodiment, the communication targets of the second user terminal 2 may be both the modification proposal support server 10 and the first user terminal 1, or only the first user terminal 1. Furthermore, there is a pattern in which the second user terminal 2 is not used at all.

[0046] The second user terminal 2, although not shown in the diagram, is equipped with a CPU, ROM, and RAM as its control unit. It also includes an input unit, display unit, storage unit, communication unit, etc., and is assumed to have the functions necessary for collaboration with the modification proposal support server 10 and the first user terminal 1. In this embodiment, a smartphone is used as the second user terminal 2. Therefore, the input and display units employ touch panels.

[0047] For example, there are three ways in which 담당자 U1 proposes home renovations to customer U2: a first pattern in which 담당자 U1 and customer U2 meet in person for a consultation; a second pattern in which 담당자 U1 and customer U2 meet online for a consultation; and a third pattern in which 담당자 U1 and customer U2 meet by phone while looking at their respective devices 1 and 2. In the first pattern (face-to-face consultation), customer U2 can view the proposed plan on the display screen of the first user terminal 1 used by the representative U1, so the second user terminal 2 is not used.

[0048] The communication network Nw may include various communication lines such as telephone lines, ISDN lines, fiber optics, mobile communication lines, satellite communication lines, CATV lines, and other dedicated lines, as well as Internet service providers (i.e., the Internet) that connect them. It may also be a collective communication network in which various communication networks such as LAN (Local Area Network), WAN (Wide Area Network), WiFi (Wireless Fidelity), Bluetooth®, and NFC (Near Field Communication) are connected in a manner that enables communication with each other. Furthermore, the form of connection may be wired, wireless, or a mixture of wired and wireless. (Hardware configuration) Figure 2 shows an example of the hardware configuration of the repair proposal support server 10 according to this embodiment. The repair proposal support server 10 has a CPU 11, ROM 12, RAM 13, HDD (Hard Disk Drive) 14, and a communication module 15.

[0049] The CPU 11 executes various programs and performs calculations. The ROM 12 stores programs necessary for startup. The RAM 13 is a work area for temporarily storing processing by the CPU 11 and storing data. The HDD 14 stores various data and programs. The communication module 15 communicates with other devices via a communication network.

[0050] (Software configuration) Figure 3 shows an example of the software configuration of the repair proposal support server 10 according to this embodiment. In other words, the CPU and other components constituting the control unit of the repair proposal support server 10 execute software (programs, etc.) to enable each part of the repair proposal support server 10 to function. The renovation proposal support server 10 of this embodiment has the following main functional units: a customer information registration unit 101, a floor plan type registration unit 102, a non-renovation area setting unit 103, a theme selection reception unit 104, a plan extraction unit 105, a plan transmission unit 106, and a storage unit 107.

[0051] The storage unit 107 stores at least the customer information database 107a, the proposal plan database 107b, and the programs and data necessary for the operation of the renovation proposal support server 10.

[0052] The customer information database 107a shall contain basic information of customer U2 and other customer information. Basic information of customer U2 refers to information such as customer U2's name, date of birth, address, and telephone number, and may also include the customer ID for logging into the modification proposal support system and the login password associated with the customer ID. Other customer information will be described later.

[0053] The proposal plan database 107b is a database that stores numerous proposal plans 30 to be proposed to customer U2, and each of the numerous proposal plans 30 is assigned one or more themes. Themes are concepts for classifying the proposal plans 30 and are hierarchically structured in database 107b. Furthermore, themes represent various "preferences (major concepts: major classification themes)" in seeking a comfortable living environment in a house, "renovation policies (medium concepts: medium classification themes)" to realize those "preferences," and "additional information (minor concepts: minor classification themes)," and are hierarchically structured according to the size of the concepts.

[0054] The following four "こだわり" (attention to detail) themes are listed as the highest-level (conceptual) themes assigned to proposal plan 30. Within proposal plan database 107b, they are positioned within the hierarchy of major theme group 110.

[0055] "1. Connection" This theme is designated as Major Theme I in Figure 4. As families grow, the way they interact with each other changes. The aim is to propose "connection designs" that meet the needs of customer U2, such as designs that allow each person to spend their time freely while naturally fostering communication. Therefore, by selecting Major Theme I "1. Connection," it is possible to extract 30 proposal plans that focus on "connection." Note that this also includes "structural connection and continuity" in a broad sense.

[0056] "2. Wellness" This theme is designated as Major Category Theme II in Figure 4. "Wellness" design, which aims to realize a comfortable and healthy lifestyle, seeks to propose plans that support a pleasant life, including bright and open spatial design, features for bedrooms conducive to restful sleep, and a healthy thermal environment. Therefore, by selecting Major Category Theme II "2. Wellness," 30 proposal plans focusing on "comfortable and healthy living" can be extracted.

[0057] "3. Housework support" This theme is designated as Major Category Theme III in Figure 4. The aim is to propose plans that create more free time through "household chore support" designs that reduce the burden of daily housework, allowing people to enjoy a more relaxed daily life by increasing the time they spend playing with their children or pursuing their hobbies. Therefore, by selecting Major Category Theme III "3. Household Chore Support," it is possible to extract 30 proposal plans that focus on "reducing the burden of daily housework."

[0058] "4. Prepare" This theme is designated as major theme IV in Figure 4. It is important to prepare for "what if" and "the future" to the same extent as the comfort of the present (normal times), and we can extract proposal plans 30 that focus on giving customer U2 a sense of security, such as space to store disaster prevention items needed in the event of a disaster, and a layout that can accommodate future care needs. Furthermore, since the proposed plan 30 differs depending on what you are preparing for, this theme is subdivided into the following three categories. "4-1. Preparing for the future" This theme allows us to extract 30 proposal plans that focus on providing a sense of security to customer U2 when they become elderly or require care. "4-2. Preparing for Disasters" This theme allows us to extract 30 proposal plans that focus on providing a sense of security in the event of a disaster. "4-3. Preparing for changes in lifestyle" This theme allows us to extract 30 proposal plans that focus on "gaining a sense of security" as lifestyles gradually change with growth.

[0059] Each of the major categories mentioned above encompasses multiple subcategories (concepts) located at a lower level. These subcategories determine the policy for modifications aimed at realizing the "attention to detail" of each major category, as described above. Examples of such themes include the following: Within the proposed plan database 107b, it is positioned within the hierarchy of sub-category theme group 111. The following subcategory themes are merely examples and are not limiting; they can be modified as appropriate without departing from the spirit of the present invention.

[0060] "1. Expanding area and making effective use of space" Since this theme concerns renovation proposals related to zoning within dwelling units, it should be considered as encompassing any of the four major themes mentioned above. Specific examples of expanding area and effectively utilizing space include the following: The adjacent Japanese-style room will be incorporated into the living / dining / kitchen area, creating a unified space. • Shorten the hallway to expand the area that can be used as a living room, dining room, and kitchen (LDK). • By reconsidering the furniture arrangement in the bedroom and changing the type of doors and storage, the limited space in the bedroom can be used more effectively (the closet can be expanded by changing the folding doors to sliding doors). • The adjacent private room is incorporated into the entrance area, expanding it into an entrance / mudroom storage area (see Figure 9). • Move the sink to the hallway to enlarge the bathroom / dressing room (see Figure 8).

[0061] "2. Ensuring brightness and a sense of openness" This theme, being a proposal for renovations related to ensuring brightness and a sense of openness within dwelling units, should be considered to fall under any of the four major theme categories mentioned above. Specific examples of ensuring brightness and a sense of openness include the following: • The entrance to the living / dining / kitchen area is made of glass, allowing light into the hallway. This makes the space appear to extend into the hallway. • Rooms are separated by louvers while allowing light, views, and air to pass through. The gentle connection between rooms allows a sense of presence to be conveyed.

[0062] "3. Reducing the burden and streamlining household chores" Since this theme involves proposals for renovations related to reducing the burden and streamlining household chores, it should be included in at least the "Household Chore Support" category of the four major categories mentioned above. Furthermore, since renovations that connect spaces can be considered to improve efficiency, it should also be included in the "Connection" category of the four major categories mentioned above. In addition, since renovations that reduce the burden of movement during old age or caregiving can also be considered, it should also be included in the "Preparation" category of the four major categories mentioned above (especially "Preparing for the Future"). Specific examples of renovations to reduce the burden and streamline household chores include the following: • Connecting the kitchen and bathroom shortens the traffic flow, and opening the sliding door allows light and air to enter the bathroom / dressing room from the kitchen side. • Connect the bathroom / kitchen area with the storage area, creating a circular flow of movement without dead ends. • The door between the washroom / dressing room and the bathroom will be changed to a sliding door to reduce the burden of walking.

[0063] "4. Reducing the burden of household chores and increasing efficiency by changing the flow of movement." Since this theme involves proposals for renovations that reduce the burden of housework and improve efficiency by changing the flow of movement, it should be included in at least one of the four major themes mentioned above: "connection" and "housework support." Specific examples of renovations that reduce the burden of housework and improve efficiency by changing the flow of movement include the following: • Create a new living space that leads from the entrance through the storage area (pantry) to the kitchen (see Figure 8). A walk-through closet will be added between the living / dining / kitchen area and the bedroom, creating a new living space that allows direct access between the kitchen and the bedroom (see Figure 7). • Connect the entrance, walk-through closet, and bathroom / dressing room to create a convenient workflow where getting ready to go out and changing clothes upon returning home can be done within the closet, and the clothes being worn can be put out for laundry in the bathroom / dressing room.

[0064] "5. Balancing communication with family and private space." This theme concerns renovation proposals related to balancing family communication and private space, and therefore should be included in at least the "Connection" category of the four major themes mentioned above. Depending on the proposed renovations, it may also be included in "Wellness" or "Household Support." Specific examples of renovations related to balancing family communication and private space include the following: • A multi-purpose space (multi-space 34d, described later) is provided in a corner of the living room to enable a variety of lifestyles (see Figure 8). • Add a split-level floor and storage space below it to a room with high ceilings.

[0065] "6. Balancing working from home with family communication" Since this theme is a proposal for improvements related to balancing remote work and communication with family, it should be included in at least one of the four major themes mentioned above: "connection" or "household support." Specific examples of improvements related to balancing remote work and communication with family include the following: • Create a home office adjacent to the entrance hall, making it easy to receive guests and create a space that allows for easy switching between work and relaxation (see Figure 9). • Create a semi-private workspace in a corner of the living room, allowing you to work while still being aware of your family's presence (see Figure 9).

[0066] "7. Expanding the space and revitalizing communication" Since this theme involves proposals for renovations related to spatial expansion and enhanced communication, it must be included in at least one of the four major themes mentioned above: "connection" and "household support." Specific examples of renovations related to spatial expansion and enhanced communication include the following: • The open-plan kitchen fosters family communication (see Figures 8 and 9).

[0067] "8. Improving the temperature of heat and cold" Since this theme concerns proposals for improvements related to heat and cold, it must be included in at least the "Wellness" category of the four major categories mentioned above. Specific examples of improvements related to heat and cold include the following: In apartment buildings, temperatures tend to be lower, especially on the side facing the common corridor, so a glass sliding door (to ensure brightness) is installed between the entrance and the interior area. • Share the warm air from the living / dining / kitchen area with the bathroom / dressing room to prevent heat shock. • Add a new window sash to the inside of openings where heat easily escapes, creating a double-glazed window to improve insulation performance.

[0068] 9. Virus countermeasures Since this topic involves proposals for modifications related to virus countermeasures, it must be included in at least the "Wellness" category of the four major categories mentioned above. Specific examples of modifications related to virus countermeasures include the following: • Install a vanity unit in the hallway, which is easily accessible from the entrance (see Figure 9).

[0069] "10. Improved ventilation" Since this theme concerns proposals for renovations related to improving ventilation, it must be included in at least one of the four major categories mentioned above: "Wellness," "Connection," or "Household Support." Specific examples of renovations related to improving ventilation include the following: • A walk-through closet is placed between the living / dining / kitchen area and the bedroom, ensuring not only an efficient flow of movement within the home but also a path for light and airflow.

[0070] "11. A good sleep environment" Since this theme concerns proposals for improvements related to creating a good sleep environment, it must be included in at least the "Wellness" category of the four major categories mentioned above. Specific examples of improvements related to creating a good sleep environment include the following: • Localized and indirect lighting is used to support restful sleep. • A wood-grain patterned dropped ceiling is used as the ceiling above the bed to promote relaxation of mind and body. • Humidity-regulating building materials are used to reduce the unpleasant dampness of summer.

[0071] "12. Improve storage by using a combination of centralized and decentralized storage." This theme proposes renovations to improve storage by using a combination of centralized and decentralized storage, and therefore should be included in at least one of the four major categories mentioned above: "Household Support" and "Connection." Specific examples of renovations to improve storage by using a combination of centralized and decentralized storage include the following: • Provide a large storage space where all family members' clothes and other belongings can be stored in one place (see Figures 8 and 9). In other words, centralized storage is proposed as part of a renovation that also incorporates decentralized storage. By utilizing small spaces and creating storage where items are used, retrieval and tidying up become easier. In other words, distributed storage is proposed as part of a renovation plan that also incorporates centralized storage.

[0072] "13. Storage Improvement" Since this theme concerns renovation proposals related to storage improvement, it must be included in at least one of the four major categories mentioned above: "Household Support" and "Connection." Specific examples of renovations related to storage improvement include the following: • Create a raised platform space with storage in a corner of the living / dining / kitchen area. • Enlarge the entrance area and incorporate a window to create a mudroom storage space (see Figure 8).

[0073] "14. Reducing the burden of household chores" Since this theme concerns proposals for renovations related to reducing the burden of household chores, it must be included in at least the "Household Support" category of the four major categories mentioned above. Specific examples of renovations related to reducing the burden of household chores include the following: • Install a workbench inside the bedroom closet to make household chores and getting ready easier (see Figure 9). The workbench can be used as an ironing board, powder corner, etc. • Create an indoor drying space in the bathroom / dressing room or near a window to improve the efficiency of household chores.

[0074] "15. Preparing for the future and emergencies" Since this theme is a proposal for renovations related to future and emergency preparedness, it must be included in at least the "Preparing" category of the four major categories mentioned above. Specific examples of renovations related to future and emergency preparedness include the following: Installing benches and handrails at the entrance reduces the risk of falls by supporting the process of putting on and taking off shoes. • Reduce the burden of movement by adding handrails and installing handwashing sinks in the toilets. • Create a designated storage area for emergency supplies so that they can be easily accessed in case of an emergency. • Movable wall-mounted storage shelves are used, allowing the shelf positions to be changed to accommodate changes such as shifts in bed or desk placement, or the introduction of a nursing care bed.

[0075] Each of the above major and minor categories contains multiple subcategories (themes) at a lower level (concept). These subcategories, as mentioned above, are supplementary information and serve to ultimately narrow down the proposed plan 30. Examples of such themes include the following: Within the proposed plan database 107b, it is positioned within the hierarchy of sub-theme group 112. The following subcategory themes are merely examples and are not limiting; they can be modified as appropriate without departing from the spirit of the present invention.

[0076] "1. Family structure" Family composition is crucial information for narrowing down the 30 proposed plans. The proposed renovations may change significantly depending on whether the number of rooms in the 20 plans being considered by customer U2 is insufficient or excessive. Therefore, this is one of the elements we want to obtain from customer U2 as much as possible. When selecting a subcategory theme, you will choose from options such as "1 person," "2 people," "3 people," "4 people," and "5 or more people." You can also select the number of adults and the number of children.

[0077] "2. My age" "My age" refers to the age of customer U2. Age information is important for determining what stage of life customer U2 is currently in. Considering customer U2's age helps prevent the extraction of unsuitable proposal plans 30. When selecting a subcategory theme, you will need to select the corresponding age number.

[0078] "3. Family members' ages" Family age refers to the ages of customer U2's family members. If customer U2 has a spouse, it refers to the spouse's age; if customer U2 has children, it refers to the children's ages. If there are multiple children, the ages of all children are checked. Age information is important for determining what life stage customer U2's family is currently in. Considering the ages of customer U2's family members helps prevent the extraction of unsuitable proposal plans 30. When selecting a subcategory theme, select the corresponding age number for each person selected in the family structure described above.

[0079] "4. Direction" The term "direction" refers to information related to the orientation of Plan 20 under consideration. When considering Plan 30, which proposes making it easier for light and wind to enter, and Plan 30, which proposes ensuring sufficient brightness inside the room, the orientation of Plan 20 under consideration becomes important information. When selecting a subcategory theme, choose which direction (north, south, east, or west) the plan under consideration generally faces.

[0080] "5. Amount of household goods" The amount of household goods refers to information used to determine how much household goods customer U2 has if they were residing in the property under consideration (Plan 20). In other words, if there is a large amount of household goods, either a Plan 30 with ample storage space or a Plan 30 that allows for renovations to improve storage space will be selected. If there is a small amount of household goods, a Plan 30 that does not consider storage space can be selected. When selecting a subcategory theme, you will choose from options such as "Many," "Average," and "Few."

[0081] "6. Hobbies" "Hobbies" refers to information related to customer U2's hobbies. In other words, proposal plans 30 are extracted that either secure space for customer U2's hobbies or propose plans 30 that allow for modifications to be made that facilitate customer U2's hobbies. When selecting a subcategory theme, you will choose from options such as "Cooking," "Reading," "Bathing," "Watching Movies," "Travel," and "Other."

[0082] "7. Whether or not you work from home" The "working from home" status refers to information used to confirm whether customer U2 or a family member of customer U2 works from home. If working from home is permitted, proposal plan 30 with a dedicated workspace is extracted; if not working from home, proposal plan 30 without a workspace is extracted. When selecting a subcategory theme, you will choose from options such as "Work from home available" or "Work from home not available."

[0083] "8. Sensible temperature" Perceived temperature refers to information used to confirm the perceived temperature of customer U2 and their family. In other words, it prevents the extraction of proposal plans 30 that would cool a room used only by people who are sensitive to cold, or proposal plans 30 that would warm a room used only by people who are sensitive to heat. When selecting a subcategory theme, you will choose from options such as "sensitive to heat," "average," and "sensitive to cold." You may have as many options as there are people selected in the family structure described above.

[0084] "9. Budget" The budget refers to information about the amount of money customer U2 can spend on renovations to their dwelling. Since the scope of the renovations will change depending on the budget, it is possible to prevent renovations that exceed the budget. By preventing renovations that exceed the budget, it is possible to prevent customer U2 from paying more than the budget, or for the person in charge U1 to cover the excess amount for customer U2. When selecting a subcategory theme, you will choose one or more options from choices such as "less than 500,000 yen", "500,000 yen to less than 1,000,000 yen", "1,000,000 yen to less than 1,500,000 yen", "1,500,000 yen to less than 2,000,000 yen", ... "9,500,000 yen to less than 10,000,000 yen", "10,000,000 yen and above".

[0085] "10. Construction period (desired move-in date)" The construction period refers to the timeframe that customer U2 is willing to spend on renovating their dwelling. The scope of the renovation and the cost may change depending on the timeframe, so if we can understand customer U2's desired construction period (desired move-in date), we can prevent discrepancies between the renovations that customer U2 wants and the actual renovations. When selecting a subcategory theme, you will choose one or more options from choices such as "within 30 days," "31 to 60 days," "61 to 90 days," "91 to 120 days," and "121 days or more."

[0086] Next, the customer information registration unit 101 has the function of receiving data containing customer U2's information and storing it as registration information in the customer information database 107a of the storage unit 107. The customer U2's information includes the basic information of customer U2 described above, as well as other customer information. Furthermore, customer U2's information is entered by either the first user terminal 1 or the second user terminal 2, transmitted from the first user terminal 1 or the second user terminal 2 to the repair proposal support server 10 via the communication network Nw, and stored in the customer information database 107a by the customer information registration unit 101.

[0087] The floor plan type registration unit 102 has the function of storing information data on the floor plan type of the dwelling unit under consideration for renovation, as declared by customer U2, in the customer information database 107a of the storage unit 107 as registered information. In other words, the other customer information in customer U2's information includes information on the floor plan type of the dwelling unit under consideration for renovation.

[0088] The basic information of customer U2 and the floor plan type of the dwelling unit being considered for renovation (other customer information) are included in the information that customer U2 entered into the designated input format when consulting with representative U1 about the renovation.

[0089] The non-renovation area setting unit 103 has the function of setting non-renovation areas Nra within the floor plan of the dwelling unit under consideration, where renovation is prohibited. In other words, the non-renovation area setting unit 103 decides which parts of the registered floor plan of the dwelling unit under consideration should be designated as non-renovation areas Nra, in consultation with the person in charge U1 and the customer U2, and reflects the result as data. In this embodiment, the non-renovation area Nra is defined as the water-related area, including the kitchen, bathroom, washroom, and toilet. In the case of apartment buildings and other multi-unit dwellings, it is common for residents to live in units on the floors above and below, and to share plumbing. Therefore, in this embodiment, the non-renovation area Nra is specifically the water-related area, and the non-renovation area setting unit 103 prohibits renovations to the non-renovation area Nra that would involve relocating the plumbing. However, since relocating the plumbing is not impossible, it may be excluded from the non-renovation area Nra if there is a strong request from the customer U2. In other words, the non-renovation area setting unit 103 may have a function to exclude the non-renovation area Nra.

[0090] To set non-renovation areas (Nra), the user displays a floor plan of the dwelling unit under consideration (non-renovation area selection screen), such as the one shown in Figure 7, on the display screen of the first user terminal 1. The user then taps to select which part of the floor plan should be designated as the non-renovation area (Nra). The selected area is then sent to the renovation proposal support server 10, and the result is reflected as the non-renovation area (Nra) in the registered floor plan of the dwelling unit under consideration. This allows the non-renovation area (Nra) to be set. In the plan under consideration 20 in Figure 7, the two areas enclosed by dashed lines are selected as non-renovation areas (Nra).

[0091] In the case of apartment buildings and other multi-unit dwellings, the management regulations for maintaining the building may include provisions regarding areas that cannot be altered. Non-renovation areas (Nra) are not limited to just water-related areas, but also include any other areas designated as non-alterable in such management regulations. Here, the areas that cannot be altered are defined as the occupied parts of each dwelling unit, and include many areas that face the outside. In particular, these include windows facing the common corridor, entrance doors, exterior walls and equipment attached to those exterior walls, as well as windows facing the outside, exterior walls, balcony railings, balcony exterior walls and equipment attached to those balcony exterior walls. In addition, structural parts of the building are also considered areas that cannot be altered.

[0092] Furthermore, the non-renovation area Nra is not limited to the water-related areas, but can be arbitrarily selected by the customer U2 or the person in charge U1. In the screen for selecting non-renovation areas, as shown in Figure 7, the dwelling units under consideration are not shown with detailed floor plans, but rather divided into general areas, making them easy to select with tap operations. Alternatively, instead of selecting the non-renovation area (Nra) by tapping, you can draw a line (for example, a dashed line as shown in Figure 7) over the floor plan of the area under consideration displayed on the non-renovation area selection screen, and then select the area you want to designate as the non-renovation area (Nra) by enclosing it with that line. When drawing the line, you can draw it in the middle of the room. In other words, you can make it possible to select only half of the room as the non-renovation area (Nra).

[0093] When setting the non-renovation area Nra using the non-renovation area setting unit 103, the system may automatically recognize the water-related areas by identifying the bathtub, washbasin, toilet, and kitchen counter shown on the floor plan, and then set the non-renovation area Nra. In this case, the range of the non-renovation area Nra may be adjustable by the person in charge U1.

[0094] The theme selection reception unit 104 has the function of receiving themes selected by customer U2 via the communication network Nw in order to extract a suitable proposal plan 30 from the proposal plan database 107b, which stores a large number of proposal plans 30 to be proposed to customer U2. Customer U2 has selected at least one of the major category theme groups 110, and if they want to narrow it down more precisely, they select one or more medium category themes from the medium category theme group 111, and further select one or more minor category themes from the minor category theme group 112.

[0095] As shown in Figure 4, it is possible to not select any of the medium-level themes or minor-level themes, and you can freely combine the medium-level themes you want to select, the medium-level themes you don't want to select, the minor-level themes you want to select, and the minor-level themes you don't want to select. If customer U2 does not select any medium-level themes or minor-level themes, theme selection will be made using only the major-level themes. If no medium-level themes are selected, theme selection will be made using the major-level themes and minor-level themes. If no minor-level themes are selected, theme selection will be made using the major-level themes and medium-level themes. In this embodiment, selecting a major-level theme is mandatory, but it is not limited to this, and there may be patterns in which no major-level theme is selected. In that case, theme selection will be made using the medium-level themes and minor-level themes. Proposal plans 30 can be extracted for each of the multiple theme hierarchies.

[0096] Furthermore, the theme selection reception unit 104 can assign priorities to multiple themes for each hierarchical level. The plan extraction unit 105 has the function of extracting proposal plan 30 from a large number of proposal plans 30, 30A, and 30B, according to the assigned priorities. By assigning priorities, it becomes clear which themes are prioritized in each of the 30 proposed floor plans.

[0097] The theme selection input operation may be performed from the first user terminal 1 of the person in charge U1, or, if online, from the second user terminal 2 of the customer U2. In other words, if person in charge U1 and customer U2 are consulting on the modification proposal in person, the theme selection input operation will be performed from the first user terminal 1. If the consultation on the modification proposal is conducted online, it may be performed from the second user terminal 2 or from the first user terminal 1.

[0098] Furthermore, the theme selection reception unit 104 has the function of saving previously received hierarchical theme selections as primary information 121 and making copies (121a). In addition, it has the function of receiving hierarchical theme selections from customer U2 on the copy 121a of primary information 121 and saving them as secondary information 122. The primary information 121 and secondary information 122 are stored in the storage unit 107, and are stored in the storage unit 107 after being linked with the customer ID. Although not shown in the diagram, the screen for selecting a theme will display a button to save and copy the theme selected by customer U2, a button to display a theme selection screen reflecting the contents of copy 121a, and a button to extract the proposed plan 30.

[0099] The plan extraction unit 105 has the function of extracting a suitable proposal plan 30 for customer U2 from the proposal plan database 107b based on the theme selection received by the theme selection reception unit 104. In other words, the extracted proposal plan 30 has the same non-modification area Nra as the plan under consideration 20 due to the non-modification area setting 103, and is in a state that follows the hierarchical theme selection by customer U2 from multiple hierarchically classified themes. Furthermore, whether in person or online (by phone), customer U2 can select a theme while consulting with the person in charge U1, making it difficult to select an incorrect theme. As a result, the extracted proposal plan 30 is likely to be suitable for customer U2 while reliably preventing the modification content from being irrelevant to the plan under consideration 20.

[0100] Furthermore, the plan extraction unit 105 is capable of extracting proposal plans 30 based on the primary information 121 and the secondary information 122. That is, when customer U2 makes a theme selection for the first time and the theme selection reception unit 104 saves the primary information 121, the plan extraction unit 105 may extract the proposal plan 30. Alternatively, the theme selection may be further accepted for a copy 121a of the primary information 121, saved as secondary information 122, and then the plan extraction unit 105 may extract the proposal plan 30. In other words, the theme selection reception unit 104 can create a copy 121a based on the primary information 121 selected by customer U2, and then use that to perform further theme selections to store secondary information 122 in the storage unit 107. Since the secondary information 122 can also become primary information when customer U2 selects a theme next time, the theme selection reception unit 104 can create and store two or more types of theme selection data. The plan extraction unit 105 then extracts a suitable proposal plan 30 for customer U2 from the proposal plan database 107b based on the multiple data (theme selections) stored in the storage unit 107. In other words, it can extract multiple types of proposal plans 30.

[0101] Furthermore, the non-modified area setting unit 103 can reset the non-modified area Nra for the proposed plan 30 extracted by the plan extraction unit 105. That is, the extracted proposed plan 30 can be used to reset the non-modified area Nra by selecting an area with a tap or by drawing a line over an area. At this time, the areas that were originally set as non-modified areas Nra can be retained while a new non-modified area Nra is reset, but it may also be possible to exclude the areas that were originally set as non-modified areas Nra from the non-modified area Nra. Furthermore, the plan extraction unit 105 can extract proposal plans 30 from among a large number of proposal plans 30, 30A, and 30B that share a common reset non-renovation area Nra, based on the proposal plan 30 with a reset non-renovation area Nra and the hierarchical theme selection by customer U2 received by the theme selection reception unit 104.

[0102] Furthermore, the display screen for the proposed plans 30 can display multiple proposed plans 30 side by side, allowing customer U2 to visually compare them. The orientation in which the multiple proposed plans 30 are displayed depends on the display screens of the terminals 1 and 2. If the display screen is landscape orientation, it is preferable to display the multiple proposed plans 30 side by side; if the display screen is portrait orientation, it is preferable to display the multiple proposed plans 30 side by side. Alternatively, a method may be adopted in which the displayed pages of the proposed plans 30 are viewed sequentially by swiping or flicking. When displaying multiple proposed plans 30 side by side, it is also possible to display a list of thumbnail images.

[0103] The plan under consideration, Plan 20, shown in the "Before" section of Figure 7, is a rectangular (long and narrow) dwelling unit, and Figure 7 illustrates an example of a renovation proposal for Plan 20.

[0104] The plan under consideration 20 shown in Figure 7 includes an entrance 22a facing a common corridor 21a, a corridor 22b extending toward the center of the dwelling unit, bedrooms 23a and 23b on either side of the corridor 22b, a bathroom (bathroom 24a, washroom / dressing room 24b, toilet 24c) adjacent to the far end of the corridor 22b, an LDK room 24 (living room 24a, dining room 24b, kitchen 24c) located at the back of the corridor 22b, a Japanese-style room 23c, and a balcony 21b. The Japanese-style room 23c can be enclosed by sliding doors and may be treated as a private room or may be included in the LDK room 24. In addition, storage areas 26s are provided in the bedrooms 23a and 23b, the Japanese-style room 23c, and the LDK room 24. In this typical grid-like plan, the wet areas (non-renovation area Nra) are located in the center of the dwelling unit, making renovation difficult. Also, referring to the plan under consideration 20A in Figure 5, the dwelling unit is divided into the area on the common corridor 21a side and the area on the balcony 21b side, with the entrance between the corridor 22b and the LDK room 24 serving as the boundary, resulting in restricted movement.

[0105] Both proposed plans 30A and 30, shown in After1 and After2 of Figure 7, select "1. Connection" and "3. Housework support" from the 110 major theme groups. In addition, at least one of the following themes from the 111 sub-theme groups is selected: "1. Expansion of area and effective use of space," "4. Reduction and efficiency of housework burden through changes in traffic flow," "5. Balancing communication with family and private space," and "13. Storage improvement." In the proposed plans 30A and 30 shown in After1 and After2 of Figure 7, the Japanese-style room is incorporated into the LDK (living room, dining room, and kitchen) area, creating a bright, spacious, and integrated space with openings on two sides. Furthermore, the kitchen is open, creating a connection between the common corridor side and the balcony side of the dwelling. In addition, the usage and size of each room have been reviewed and the area has been redistributed. Note that in Figure 7, after1 and after2, proposal plans 30A and 30 are shown as different proposal plans 30A and 30 because, even though the major and medium classification themes are the same, the selected minor classification themes are different.

[0106] Figure 8 provides a detailed explanation of After2 in Figure 7, with the family structure selected as the sub-theme: "husband" + "wife" + "one child." The child is an infant. The proposed plan 30 shown in Figure 8 includes an entrance hall 32a, a corridor 32b, an extended earthen floor area 32c, a bedroom 33a, an LDK room 34 (living room 34a, dining room 34b, kitchen 34c, multi-purpose space 34d), a bathroom 35a, a dressing room 35b, a toilet 35c, a washbasin 35d, a first closet 36a, a second closet 36b, a balcony 31b, and multiple storage areas 36s.

[0107] The entrance 32a faces the common corridor 31a and is integrally formed with the earthen floor extension 32c. The earthen floor extension 32c extends the earthen floor area of ​​the entrance 32a and is located on the west side of the entrance 32a. The earthen floor extension 32c functions as both a passageway and a storage space. In addition, there is a window on the common corridor 31a side, allowing for ventilation and natural light.

[0108] The first closet 36a and the second closet 36b are located on the west side of the corridor 32b, and an entrance is formed in the partition wall between the first closet 36a and the second closet 36b, allowing movement between them. Furthermore, the first closet 36a is adjacent to the earthen floor extension 32c, and it is possible to move between the two. The first closet 36a can also be accessed from the corridor 32b. The first closet 36a is a storage space that can be used by all family members from three directions, and it is large enough to be used as a room, so various items can be stored in addition to clothes. The second closet 36b is adjacent to the kitchen 34c in the LDK room 34, and it is possible to move between the two rooms. Because the second closet 36b is adjacent to the kitchen 34c, it can easily function as a pantry, and it can also easily function as a workspace by installing an ironing board, and it can also easily function as a powder corner by installing a dressing table. The dwelling unit in proposed plan 30 is equipped with a first closet 36a and a second closet 36b, creating a continuous flow from the earthen floor extension 32c to the kitchen 34c. This allows for a smooth storage process, for example, by bringing groceries into the first closet 36a to hang up coats, storing items on the pantry shelves in the second closet 36b, and then storing items in the refrigerator in the kitchen 34c. In the proposed plan 30 shown in Figure 8, by including a first closet 36a and a second closet 36b, the dwelling unit is not divided into the area on the common corridor 31a side and the area on the balcony 31b side, but is connected by a circulation route that spans both areas. Furthermore, including the corridor 32b, a circular circulation route is formed consisting of the entrance 32a, corridor 32b, kitchen 34c, second closet 36b, first closet 36a, and the earthen floor extension 32c.

[0109] The washbasin 35d is located facing the corridor 32b, separate from the changing room 35b. This makes it possible to separate the people who use the washbasin 35d from the people who use the changing room 35b.

[0110] Kitchen 34c is not separated from living room 34a and dining room 34b by a wall, and an island kitchen is used to further enhance the sense of openness. Furthermore, because branch pipes for piping run through the underfloor space do not require major renovations involving the relocation of pipes, an island kitchen can be adopted.

[0111] The multi-space 34d is separated from the LDK room 34 by a movable partition wall 34w, so it can be opened up at any time to become an integrated space with the LDK room 34. In addition, the multi-space 34d can be fitted with a bed and desk and used as a children's room in the future.

[0112] Figure 9 shows Plan 30B, another proposed plan for the grid-like layout, in which the family structure is defined as "husband" + "wife," and both the husband and wife are 60 years of age or older. Furthermore, due to working from home, they have business clients and want to minimize household chores as much as possible. The proposed plan 30B shown in Figure 9 includes an entrance hall 32a, a corridor 32b, an extended earthen floor area 32c, a bedroom 33b, a first workspace 33d, an LDK room 34 (living room 34a, dining room 34b, kitchen 34c, second workspace 34e), a bathroom 35a, a dressing room 35b, a toilet 35c, a washroom 35e, a first closet 36a, a balcony 31b, and multiple storage areas 36s.

[0113] The entrance 32a faces the common corridor 31a and is integrally formed with the earthen floor extension 32c. The earthen floor extension 32c extends the earthen floor area of ​​the entrance 32a and is located on the east side of the entrance 32a. The earthen floor extension 32c functions as storage space, but also as a community space for welcoming guests. In addition, there is a window on the common corridor 31a side, allowing for ventilation and natural light.

[0114] Bedroom 33b is located on the west side of corridor 32b. The first workspace 33d is located on the east side of corridor 32b and south of the earthen floor extension 32c. The first workspace 33d can be accessed from both the earthen floor extension 32c and the corridor 32b. When entering or exiting from the earthen floor extension 32c, there is no need to go around to the corridor 32b, thus preventing visitors from entering the private space.

[0115] The first closet 36a is located on the west side of the corridor 32b and south of the bedroom 33b. Furthermore, the first closet 36a is accessible from both the corridor 32b and the bedroom 33b. It is also accessible from the corridor 32b. The first closet 36a is adjacent to the kitchen 34c in the LDK room 34, and is accessible from both the LDK room and the kitchen 34. In short, the first closet 36a is a storage space accessible to all family members from three directions, and is large enough to function as a room, allowing for the storage of various items in addition to clothing. The first closet, 36a, is adjacent to the kitchen, 34c, making it easy to use as a pantry. It can also be used as a workspace by installing an ironing board, and as a powder corner by installing a dressing table. In the proposed plan 30B, the first closet 36a is included, creating a continuous flow from the kitchen 34c to the bedroom 33b. This allows for a more efficient workflow for household chores. In the proposed plan 30B shown in Figure 9, the inclusion of a first closet 36a ensures that the dwelling unit is not divided into the area on the common corridor 31a side and the area on the balcony 31b side, but is connected by a circulation route that spans both areas. Furthermore, including the corridor 32b, a circular circulation route is formed consisting of the bedroom 33b, corridor 32b, kitchen 34c, and first closet 36a.

[0116] The washroom 35e is separated from the dressing room 35b and is adjacent to it via a corridor 32b. This makes it possible to separate the people who use the washroom 35e from those who use the dressing room 35b.

[0117] Kitchen 34c is not separated from living room 34a and dining room 34b by a wall, and a peninsula kitchen is used to further enhance the sense of openness. Furthermore, because branch pipes for piping run through the underfloor space do not require major renovations involving the relocation of pipes, a peninsula kitchen can be adopted.

[0118] The second workspace 34e is located in a corner of the living room 34a. Furthermore, this second workspace 34e is enclosed by walls except for the entrance, which does not have a door. Therefore, this second workspace 34e is perceived as a semi-private room. By placing the semi-private second workspace 34e in a corner of the living room 34a, one can work while still being aware of the presence of family members.

[0119] Proposal plans 30, 30A, and 30B are not limited to the examples above, and exist for each floor plan type. Furthermore, even for the same floor plan type, if the selected theme is different, the resulting proposal plans 30, 30A, and 30B are also likely to be different.

[0120] The plan transmission unit 106 has the function of transmitting the data of the proposed plan 30 extracted by the plan extraction unit 105 to at least the first user terminal 1 of the two user terminals 1 and 2. That is, if the person in charge U1 and the customer U2 are consulting on the renovation proposal in person, it is sufficient for the data of the proposed plan 30 to be transmitted only to the first user terminal 1. If the consultation on the renovation proposal is conducted online, the data of the proposed plan 30 may be transmitted to both the first user terminal 1 and the second user terminal 2, or it may be transmitted only to the first user terminal 1, and the screen may be shared from the first user terminal 1 so that it can be viewed on the second user terminal 2.

[0121] As described above, the storage unit 107 stores at least the customer information database 107a, the proposal plan database 107b, and the programs and data necessary for the operation of the renovation proposal support server 10. In addition, the data of the proposal plan 30 extracted by the plan extraction unit 105 is stored in the storage unit 107 after being linked to the customer ID. Furthermore, the data of the proposal plan 30 may be compiled into a database together with the floor plan type of the plan under consideration 20 and the themes 110, 111, and 112 selected by customer U2.

[0122] Each functional unit is implemented by a program executed on the hardware resources of the computer constituting the modification proposal support server 10, such as the CPU 11, ROM 12, and RAM 13. These functional units may be read as "means," "modules," "units," or "circuits." Furthermore, each functional unit may be implemented not only on the modification proposal support server 10, but also by distributing its functions across multiple server devices and enabling them to communicate with each other via a communication network, thereby achieving the same functionality as the modification proposal support server 10. In addition, each DB of the storage unit 107 can be placed on an external storage device on the communication network. Moreover, computer programs and application programs may be stored on a storage medium that is readable by the computer.

[0123] (Proposal process for renovations) Next, I will explain the process for submitting a renovation proposal.

[0124] When proposing modifications, customer U2 can choose whether to have a face-to-face meeting with representative U1 or a consultation online (sometimes by phone). If the consultation is conducted face-to-face with representative U1, the explanation will be given to customer U2 on the display screen of the first user terminal 1 used by representative U1. If the consultation regarding modification proposals is conducted online, the same explanation screen will be displayed on the display screen of the first user terminal 1 used by representative U1 and on the display screen of the second user terminal 2 used by customer U2, and the explanation will be given to customer U2 from there.

[0125] The following explanation will focus on the case of a face-to-face modification proposal. Therefore, all operations related to inputting various information will be performed from the first user terminal 1, and the modification proposal support server 10 will be able to acquire and accept the data transmitted from the first user terminal 1. Furthermore, when performing operations related to various information inputs using the first user terminal 1, the input form data is sent to the first user terminal 1 from the modification proposal support server 10 in advance. The person in charge U1 or customer U2 can then enter the necessary information into each field of the input form and send the data by pressing the submit button on the input form, thereby sending the necessary information to the modification proposal support server 10. The input form will display fields for entering the floor plan type for the 20 dwelling units under consideration, setting the non-renovation area (Nra), and selecting a theme. These fields may be updated and displayed sequentially according to the procedure, or they may all be displayed on a single page.

[0126] When making a renovation proposal in person, the first step is to input customer U2's customer information from the first user terminal 1. The entered customer information is stored in the customer information database 107a. In other words, customer U2 is registered as a user. Once a user registers, the modification proposal support server 10 sends data for an input form displaying the necessary items for a modification proposal to the first user terminal 1, and the first user terminal 1 displays the input form on its screen.

[0127] Next, in the input form, enter the floor plan type for the dwelling unit under consideration (Plan 20) that customer U2 is considering renovating. For example, let's say it's a grid-like layout.

[0128] Next, in the input form, in the item for setting the non-renovation area Nra, the non-renovation area Nra for the target plan 20, which is a grid-shaped plan, is set. That is, a general floor plan as shown in Figure 7 is displayed in the item, and the non-renovation area Nra is set by tapping or automatically.

[0129] Next, in the input form, in the section for selecting a theme, customer U2 selects the theme they wish to modify from a hierarchically categorized list of themes. The theme selection is done starting with the major theme group 110, then the medium theme group 111, and finally the minor theme group 112. Note that the subcategory theme group 111 and the minor category theme group 112 can be left unselected, so selecting only the major category theme group 110 is also acceptable. Patterns where neither the subcategory theme group 111 nor the minor category theme group 112 is selected are also acceptable.

[0130] Once all fields in the input form have been filled in and the input information has been sent to the modification proposal support server 10, the modification proposal support server 10 receives this information and the plan extraction unit 105 extracts the proposal plan 30. The extracted proposal plan 30 was selected from among numerous proposal plans 30, 30A, and 30B according to the hierarchical theme selection by customer U2, and furthermore, the non-renovation area Nra is common to all of them.

[0131] The extracted data for the proposed plan 30 is transmitted from the renovation proposal support server 10 to the first user terminal 1 via the communication network Nw. Person in charge U1 displays the extracted proposal plan 30 on the display screen of the first user terminal 1 and explains the proposal plan 30 to customer U2.

[0132] The renovation proposal is then submitted in the manner described above. However, renovation proposals made based on the renovation proposal support system of this embodiment are mainly made in the initial stages when customer U2 has considered renovating their home, and before customer U2's renovation requests have been finalized. Once customer U2's renovation requests have become somewhat clearer, the person in charge U1 may approach customer U2 about renovation proposals using other methods.

[0133] This embodiment provides the following excellent effects. In other words, the floor plan type registration unit 102 registers the floor plan type of the dwelling unit (plan under consideration 20) that is being considered for renovation, the non-renovation area setting unit 103 sets the non-renovation area Nra of the floor plan of the dwelling unit (plan under consideration 20) that is prohibited from being renovated, the theme selection reception unit 104 accepts the theme selection by customer U2 in hierarchical order, and the plan extraction unit 105 extracts proposal plans 30 from a large number of proposal plans 30 that have a common non-renovation area Nra according to the theme selection by customer U2 in hierarchical order. Thus, proposal plans 30 that have the same floor plan type as the dwelling unit (plan under consideration 20) and have a common non-renovation area Nra are extracted from a large number of proposal plans 30, 30A, 30B, and further the proposal plans 30 can be narrowed down according to the theme selection by the customer in hierarchical order. Therefore, in the initial stages when customer U2 considers renovating an apartment building or other multi-unit housing, it is possible to prevent them from deviating from the direction of the renovation or selecting a proposal plan for a floor plan type that cannot be adopted, and to propose a suitable renovation to customer U2.

[0134] Furthermore, since the non-renovation area setting unit 103 prohibits renovations of non-renovation areas Nra that involve relocating piping, it is possible to prevent the extraction of proposal plans that require extensive renovations of water-related areas involving the relocation of piping. As a result, proposal plans 30 that do not significantly change the lifestyle from the floor plan type of the dwelling unit under consideration (plan under consideration 20) can be extracted, so suitable renovation proposals can be made to customer U2 at the initial stage when customer U2 considers renovating an apartment building or other multi-unit dwelling.

[0135] Furthermore, since the non-renovation area Nra is any area selected by customer U2 from the dwelling unit (plan under consideration 20), it is possible to extract a proposal plan 30 in which the area selected by customer U2 is not renovated. This makes it possible to propose suitable renovations to customer U2 at the initial stage when they begin to consider renovating their apartment building or other multi-unit housing.

[0136] Furthermore, the plan extraction unit 105 is capable of extracting proposal plans 30 for each of multiple theme hierarchies. Therefore, by narrowing down the themes at relatively broad conceptual hierarchies, a large number of proposal plans 30 can be extracted, or by narrowing down to relatively small conceptual hierarchies, proposal plans 30 that more precisely match the customer U2's needs can be extracted.

[0137] Furthermore, the numerous proposal plans 30 include both proposal plans 30 that display the floor plan of the entire dwelling unit and proposal plans for renovating only a part of the dwelling unit. Therefore, both proposal plans 30 that display the floor plan of the entire dwelling unit and proposal plans for renovating only a part of the dwelling unit can be presented to customer U2. This allows for the provision of suitable renovation proposals to customer U2 at the initial stage when they begin considering renovations to their apartment building or other multi-unit dwelling.

[0138] Furthermore, the first user terminal 1 receives the data of the proposed plan 30 transmitted by the plan transmission unit 106 of the renovation proposal support server 10 and makes it available for display on the display screen. This allows the proposer U1 to discuss the renovation proposal with customer U2 while showing them the proposed plan 30 displayed on the screen. In other words, the proposer U1 can have a face-to-face conversation with customer U2, which increases the depth of communication and makes it easier to convey the appeal of the proposed plan 30.

[0139] Furthermore, the second user terminal 2 receives the data of the proposed plan 30 transmitted by the plan transmission unit 106 of the renovation proposal support server 10 and makes it available for display on the display screen. Therefore, the proposed plan 30 extracted by the plan extraction unit 105 can be viewed simultaneously not only on the proposer U1's first user terminal 1 but also on the customer U2's second user terminal 2. This allows proposer U1 and customer U2 to discuss renovation proposals remotely, without being restricted by location or time.

[0140] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to achieve virtually zero carbon dioxide emissions, and for the achievement of the Sustainable Development Goals (SDGs). In the construction industry, efforts are also being made to use wood, which reduces carbon dioxide emissions, for buildings. In this embodiment, since home renovations can be promoted, the generation of unnecessary waste materials can be reduced. Furthermore, by renovating the home, it becomes possible to continue living in it. Therefore, it can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and to the achievement of the SDGs (Goals 11, 12, 13, and 15).

[0141] [Variation] The embodiments to which the present invention can be applied are not limited to those described above, and can be modified as appropriate without departing from the spirit of the invention. Modifications are described below. The following modifications may be combined as much as possible. Furthermore, in each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and their descriptions are omitted or simplified.

[0142] [Variation 1] The subcategory theme group 112 includes "1. Family structure," "2. My age," and "3. Family members' ages." Therefore, by using the copy function, which is one of the functions of the theme selection reception unit 104, it is possible to extract proposal plans 30 for a single family in chronological order. In other words, family structure changes with life stage, and it is desirable that the layout of the dwelling changes with each life stage. For example, if a family consists of a couple and one child, and the child is 5 years old, then when considering the situation over spans of 5 years, 10 years, and 20 years, there will be a suitable layout plan for each stage, and the plan extraction unit 105 can extract 30 such proposed plans for different life stages. To explain in more detail, first, the theme selection reception unit 104 extracts the current proposal plan 30 and saves it as primary information 121, and also makes a copy of it. The current proposal plan 30 has a family structure of "husband and wife + 1 child" and "the child is 5 years old". For example, let's assume both husband and wife are 30 years old. Then, for the copy 121a, the theme selection "child is 10 years old (husband and wife are 35 years old)" is made and saved as secondary information 122. This process is repeated until "child is 15 years old (husband and wife are 40 years old)" and "child is 25 years old (husband and wife are 50 years old)", which allows for the extraction of the current proposal plan 30, the proposal plan 30 for 5 years from now, the proposal plan 30 for 10 years from now, and the proposal plan 30 for 20 years from now. Furthermore, once children have left home, the family structure will change, so in that case, for example, you can extract Plan 30 for proposals based on "a couple only, age 60".

[0143] [Variation 2] The subcategory theme 111 includes the theme "1. Area expansion and effective use of space." In the above embodiment, when the theme selection reception unit 104 accepts the theme selection, for example, this theme is selected. However, the renovation proposal support server 10 in this modified example is equipped with a proposal plan editing means that can edit the extracted proposal plan 30 to expand or reduce the area. More specifically, the proposal plan editing means has the function of shifting the position of wall lines or furniture that form the boundary between the first room, which is the subject of consideration for expansion or reduction in area, and the second room adjacent to the first room, on the proposal plan 30. Alternatively, it may be possible to delete wall lines or furniture. Furthermore, it may be possible to change the use of the first and second rooms displayed on the proposal plan 30.

[0144] According to this modified version, it becomes possible to edit the extracted proposal plan 30 by enlarging or reducing its area. Therefore, even if a proposal plan 30 that closely matches customer U2's requirements cannot be extracted, the proposal plan 30 can be made closer to customer U2's requirements, and a suitable renovation proposal can be made to customer U2.
