Description

[Technical Field]

[0001] The present invention relates to a house that can be lived in for a long time as the resident's life stages change. [Background technology]

[0002] Generally, over the years of living in a home, damage and deterioration occur in various parts of the building, requiring regular maintenance and repairs. Furthermore, while it is not easy to change the floor plan of a typical home once it is built, many people become dissatisfied with the layout after living there for many years. This is because typical homes are not adequately adapted to the changing life stages of their residents. For example, if a child's room is built as the child grows, once the child leaves home to go to school or get a job, it is likely to become an unused room with no other purpose. Renovating this room to make it a space for hobbies, free space, or for guests will incur significant renovation costs in addition to the maintenance and repair costs mentioned above.

[0003] Regarding the layout of the house, the house of JP 2000-145171 leaves the exterior and interior walls around the building as they are, but arranges movable partition furniture or movable partition walls to divide the living area into two or expand it, allowing for a variety of layouts to be realized. Also, the house of JP 2000-145170 is equipped with movable shelves, which similarly allow for the living area to be divided into two or expanded. [Prior art documents] [Patent documents]

BEST MODE FOR CARRYING OUT THE INVENTION

[0016] The best mode for carrying out the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a house, reference numeral 2 denotes a building, arrow X denotes the east-west direction, and arrow Y denotes the north-south direction.

[0017] Figures 1(A) and 1(B) show the east and south sides of building 2, and Figures 2(A) and 2(B) show the west and north sides of building 2. House 1 consists of building 2, foundation 3, and site 4, with foundation 3 built on site 4 and building 2 built on foundation 3. The orientation of building 2 is an example and is not limited to this.

[0018] The outer periphery of the building 2 is rectangular in plan view, and along the periphery are arranged exterior walls 11, which serve as load-bearing walls. Each of the exterior surfaces of the exterior walls 11 is covered with clapboards 12, and the roof 13 has a gable structure.

[0019] First, the exterior of building 2 will be explained. On the east side (see Figure 1(A)), there is a doorway 14 and a kitchen window 15 at first floor height. The doorway 14 is equipped with eaves 14A and a front door 14B. Above the doorway 14 and the first floor window 15, there are two windows 16 and 17 for the living rooms on the second floor.

[0020] The south side of building 2 (see Figure 1(B)) has an opening 18 facing the dining room on the first floor. A storage compartment 19B for window 19A is located next to opening 18, and by moving window 19A sideways toward storage compartment 19B, the entire opening 18 can be opened.

[0021] The west side of building 2 (see Figure 2(A)) has a window 21 facing the living room on the first floor, a small window 22 facing the multipurpose space on the first floor, and a window 23 facing the bathroom on the first floor. Above these three first-floor windows 21-23, two windows 24 and 25 facing the multipurpose space on the second floor are provided.

[0022] The north side of the building 2 (see FIG. 2(B)) is provided with a window 26 facing the washroom on the first floor.

[0023] Next, regarding the interior of building 2, as shown in Figure 3, a staircase 27 connecting the first floor 28 (Figure 3(A)) and the second floor 29 (Figure 3(B)) is located approximately in the center of building 2 (north of center O), facing east-west (Y direction).

[0024] As shown in Figure 3(A), on the first floor of building 2, the entrance, hall, washroom, toilet, kitchen, dining room, living room, multipurpose space, dressing room, and bathroom are arranged in clockwise order around staircase 27.

[0025] In the layout of the first floor, the entrance and hall are located on the east side of staircase 27, and the washroom and toilet are located on the north side of the entrance and hall. The kitchen is located in the southeast corner south of staircase 27, the dining room is located south of staircase 27, the living room is located in the southwest corner south of staircase 27, the dressing room is located north of staircase 27, and the bathroom is located in the northwest corner. The multipurpose space is located west of staircase 27, between the living room and dressing room.

[0026] In the first floor layout, a first interior wall 31, which separates the entrance hall from the kitchen, extends partway at a right angle from the center of the east-facing exterior wall 11A, leaving a space between it and the downhill end of the staircase 27. A second interior wall 32, which extends in the same direction as the first interior wall 31 and is adjacent to the uphill side of the staircase 27, extends on the extension line of the first interior wall 31, leaving a space between it and the west-facing exterior wall 11C. These first and second interior walls 31 and 32 form part of the load-bearing walls.

[0027] A third inner wall 33 extends from the midpoint of the straight line connecting the first inner wall 31 and the second inner wall 32 in a perpendicular direction (facing north) to the middle of the hall. This third inner wall 33 forms a passageway 37 connecting the hall and the dining area. In addition, a fourth inner wall 34 extends from a position adjacent to the descending end of the stairs 27 toward the north-facing outer wall 11D in the same direction as the third inner wall 33, leaving a space between it and the outer wall 11D and extends partway. These third inner wall 33 and fourth inner wall 34 form part of the load-bearing walls.

[0028] The entrance hall and toilet, and the hall and washroom are separated by partition walls 35 extending in the east-west direction (Y direction). A passageway 36 is provided between the hall and washroom, and a passageway 37 is provided between the hall and dining room. A wide passageway 38 is provided between the living room and multipurpose space, a passageway 39 is provided between the multipurpose space and the dressing room, and a passageway 40 is provided between the dressing room and washroom.

[0029] The bathroom is separated by a partition wall 41, and can be accessed by opening a bathroom door 42, and the toilet can be accessed by opening a sliding door 43.

[0030] On the first floor of Building 1, when you go up from the entrance to the hall, corridors 37-40 are formed around the staircase 27, allowing you to move clockwise to the dining room, kitchen, living room, multipurpose space, dressing room (bathroom), washroom (toilet), and hall. You can also move counterclockwise to the washroom (toilet), dressing room (bathroom), multipurpose space, living room, dining room (kitchen), and hall.

[0031] As shown in FIG. 3(B), on the second floor of the building 2, a first living room, a second living room, a multipurpose space, and a third living room are arranged around a staircase 27.

[0032] In the layout of the second floor, the first living room is located at the northeast corner of the staircase 27, the second living room is located at the southeast corner of the staircase 27, the multipurpose space is located at the southwest corner of the staircase 27, and the third living room is located at the northwest corner of the staircase 27. A buffer zone is provided between the first and third living rooms.

[0033] In the second floor layout, a fifth interior wall 44 that separates the first and second living rooms extends partway at a right angle from the center of the east-facing exterior wall 11A, leaving a space between it and the staircase 27. A sixth interior wall 45 extends in the same direction as the fifth interior wall 44, adjacent to the uphill side of the staircase 27, on the extension line of the fifth interior wall 44, leaving a space between it and the west-facing exterior wall 11C.

[0034] The fifth inner wall 44 is located directly above the first inner wall 31 on the first floor, and the sixth inner wall 45 is located directly above the second inner wall 32 on the first floor. These fifth inner wall 44 and sixth inner wall 45 form part of the load-bearing wall.

[0035] A pillar 46 is placed midway along the line connecting the fifth interior wall 44 and the sixth interior wall 45. The pillar 46 is located directly above the pillar at the south end of the third interior wall 33 on the first floor, and together with the fifth interior wall 44 and the sixth interior wall 45, forms part of a load-bearing wall.

[0036] In the second floor layout, an opening 47 is provided on the south side of the staircase 27, directly above the dining room on the first floor, and this opening 47 forms an open-ceiling space from the first floor to the second floor. A passage 48 is formed between the opening 47 and the staircase 27.

[0037] On the second floor of Building 1, if you go up the stairs 27 from the first floor, you can move clockwise to the third living room, buffer zone, first living room, second living room, corridor 48, and multipurpose space. Also, if you move counterclockwise, you can move to the multipurpose space, corridor 48, second living room, first living room, buffer zone, and third living room.

[0038] By arranging the walls on the first floor, which form the load-bearing walls of Building 2, and by arranging the walls on the second floor, it is possible to arrange the interiors of the first and second floors of Building 2 in a variety of ways to suit changing living stages.

[0039] FIG. 4 shows the change in layout from the first and second floors of building 2 in life stage 1 to the first and second floors of building 2 in life stage 4. It is also possible to start from life stage 4 and move to life stage 1. The layouts for each of life stages 1 to 4 will be described below with reference to FIGS. 5 to 8.

[0040] Figures 5(A) and (B) show the layout of the first and second floors assuming life stage 1. The illustrated examples assume a life stage of, for example, a three-person household consisting of a couple and one child, or a four-person household consisting of a couple and two children (one of whom is an infant).

[0041] On the south side of the first floor (Fig. 5(A)), from right to east, there are a kitchen, dining room, and living room. In the example shown, there is a refrigerator 51 and a counter 52 in the kitchen, a dining table 53 in the dining room, and a sofa 54 and a TV stand 55 in the living room.

[0042] One of the features of the first floor is that the multipurpose space between the living room and the dressing room is used for housework and childcare. A desk 56 is placed facing the window 22 in the multipurpose space, and behind it, between the second interior wall 32, a baby bed 57 is placed facing north-south (X direction). This arrangement allows parents to visually check on their infant from the kitchen.

[0043] The desk 56 is located next to the living room, so it can also be used as a place for children to study, such as doing their homework. On the north side of the first floor, there is a sliding door 58 between the dressing room and the washroom. Reference number 59 is a windowsill, and reference number 60 is a clothes drying rack.

[0044] On the north side of the second floor (Figure 5(B)), the first room in the northeast corner will be used as a bedroom and study for either spouse, and the third room in the northwest corner will be used as a bedroom for either spouse. The second room in the southeast corner on the south side will be used as a children's room. The first room on the north side will contain a bed 61 and a desk 56, the third room will contain a bed 61 and storage furniture 62, and the second room on the south side will contain a child's bed 61 and a desk 56.

[0045] A walk-in closet (WIC) is located in the buffer zone between the first and third living rooms on the north side. A partition wall 62 is placed between the walk-in closet and the first living room, leaving a passageway 63, and a partition wall 64 is placed between the walk-in closet and the third living room, leaving a passageway 65, with a partition (curtain) 66 placed in the passageway 65.

[0046] The above layout allows access to the walk-in closet from the first and third rooms, and by placing a walk-in closet (buffer zone) between the first and third rooms, noises made while sleeping and the sounds of one's favorite music are reduced, ensuring each person has their own private space.

[0047] Between the first and second rooms, a passageway 67 is formed, leaving only the fifth interior wall 44, allowing parents and children to move back and forth. A partition wall 68 extends from the pillar 46 toward the sixth interior wall 45, and a bookshelf 69 is placed between the partition wall 68 and the passageway 48. The bookshelf 69 is located near the first and second rooms, allowing parents and children to display their favorite books.

[0048] The multipurpose space on the west side is used as a children's playroom, and is furnished with sofas 54 and tables 70. The playroom on the second floor and the kitchen on the first floor are connected by a central atrium space (opening 47), allowing parents to enjoy conversations with their children on the second floor while working in the kitchen on the first floor.

[0049] Figures 6(A) and (B) show the layout of the first and second floors assuming life stage 2. Life stage 2 assumes a four-person household consisting of a couple and two growing children.

[0050] The south side of the first floor (Fig. 6(A)) is no different from the south side of the first floor in Fig. 5(A). In the multipurpose space between the living room and the dressing room, a desk 56 is placed facing north with its back to the living room, and a bookshelf 69 connected to the second interior wall 32 is placed facing east-west (Y direction), leaving a one-person passage 71 between the living room and the desk. The placement of the desk 56 and bookshelf 69 provides a space / place to be alone near the spacious living room, where one can concentrate alone and focus on work or study.

[0051] On the second floor (Figure 6(B)), the first living room in the northeast corner on the north side is used as the couple's bedroom, the third living room in the northwest corner on the north side is used as the first child's room, and the second living room in the southeast corner on the south side is used as the second child's room. A partition piece of furniture 72 is placed between the first and third living rooms, ensuring privacy for the couple and their children. The first and third living rooms are separated by a bookshelf 69 that continues from the fifth interior wall 44 and a sliding door 73, ensuring privacy for the couple and their children. Access to the first and second living rooms is also ensured from the corridor 48.

[0052] The multipurpose space on the west side is furnished with sofas 54 and tables 70 and will continue to be used as a playroom, as in Figure 5(B).

[0053] Figures 7(A) and (B) show the layout of the first and second floors assuming life stage 3. Life stage 3 is assumed to be, for example, a couple living together after their two children have moved out.

[0054] The south side of the first floor (Fig. 7(A)) is almost the same as the south side of the first floor in Fig. 5(A). A counter 52 and other furniture are placed in the kitchen, a dining table 53 in the dining room, and a sofa 54 and TV stand 55 in the living room. In the multipurpose space between the living room and the dressing room, a desk 56 is placed facing north with its back to the living room, just like in Fig. 5(A), and storage furniture 62 is placed behind the sofa 54 in the living room, leaving a one-person passageway 74 between the living room and the dressing room. The placement of the desk 56 and storage furniture 62 makes it possible to secure a space near the spacious living room where one can concentrate on studying or working alone.

[0055] By placing a partition (curtain, etc.) 66 that can be opened and closed between the multipurpose space and the changing room, privacy can be ensured in the changing room when children, grandchildren, or friends come to visit. If the couple is elderly, they can maintain their own pace and rhythm of life.

[0056] On the second floor (Figure 7(B)), the third living room on the north side and the multipurpose space on the west side are used as free space FS, the first living room on the north side is used as a bedroom for the couple, and the second living room on the south side is used as a spare room or a guest accommodation space. The free space FS and the second living room can be used as a resting space or accommodation space when children, grandchildren, or friends come to visit.

[0057] Between the first living room on the north side and the free space FS is a walk-in closet (WIC) that can be accessed from either side. An openable partition (curtain, etc.) 66 is placed at the entrance on the free space FS side, ensuring privacy for the first living room. A door 73 for accessing the first living room is placed between the fifth interior wall 44 and the pillar 46, ensuring both privacy and access to the first living room. Reference numeral 75 denotes a rug.

[0058] Figures 8(A) and (B) show layouts of the first and second floors assuming life stage 4. As life stage 4, for example, it is assumed that one person lives alone in building 2.

[0059] On the south side of the first floor (Figure 8(A)), the living room on the first floor in Figure 5(A) is used as a bedroom, with a bed 61 placed on the west-facing window 21 side and storage furniture 62 of roughly the same length as the bed 61 placed parallel to the bed 61. This separates the dining room from the bedroom. In the adjacent multipurpose space to the north, a desk 56 is placed facing the west-facing window 22, and behind it, storage furniture 62 is placed facing the same direction as the desk 56, attached to the second interior wall 32.

[0060] A one-person passage 76 is secured between the two storage furniture pieces 62, 62, and a one-person passage 77 is secured between the storage furniture piece 62 behind the desk 56 and the dressing room. The living room space and multipurpose space to the west of the dining room can be used as a bedroom and study for the resident.

[0061] On the second floor (Fig. 8(B)), the first and third living rooms on the north side are each used as guest rooms, with two beds 61 in the first living room and a bed 61, desk 56, and storage furniture 62 in the third living room. A partition wall 78 separates the first and third living rooms, ensuring privacy for each room.

[0062] The second living room on the south side is used as a spare room and is furnished with a desk 56 and storage furniture 62. A partition wall 79 and a sliding door 73 are placed between the first and third living rooms, ensuring access to the first living room and privacy. The multipurpose space is furnished with a sofa 54, TV stand 55, and table 70 and is used as a second living room. The second floor can be used as a lodging space for relatives and friends, who can relax in the second living room.

[0063] The above layout is ideal for elderly people living alone, using the first floor as their living space and the second floor as a place for relatives and children to come and relax or stay overnight.It is also ideal for single people living alone, using the first floor as their living space and offering the second floor as a place for friends to stay.

[0064] If a single person lives alone in the above arrangement and then marries, the couple can move from life stage 4 to life stage 1 and of course change the layout to suit life stage 1.

[0065] According to the house of the present invention, the layout of the first and second floors inside the building can be changed in accordance with changes in the life stage, whether 10, 20, or 50 years from now, to accommodate long-term use, and residents will be able to enjoy a rich life for many years. [Industrial Applicability]

[0066] The present invention can be used as a house that can be used for a long time as life stages change. [Explanation of symbols]
