Abstract
Description
Technical Field
[0001] The present invention relates to a group of buildings, and particularly to a group of buildings constructed on a subdivided land for sale.
Background Art
[0002] Generally, in many cases, similar-structured houses H are constructed and sold on each of a plurality of subdivided lands (eight sections in the figure) 101 provided by partitioning a piece of land 100 of a certain size as shown in FIG. 3. Specifically, the land 100 is surrounded by roads 2 on all four sides, the subdivided lands 101 are partitioned into squares of substantially the same area, and the adjacent subdivided lands 101 are arranged facing each other. Also, the adjacent houses H are arranged facing each other (in FIG. 3, the building built on the subdivided land 101a is arranged facing the houses H built on each of the subdivided lands 101b and 101c).
[0003] In addition, each subdivided land 101 is provided with a parking lot P facing the road 2 where cars can enter and exit from the north-south direction. The house H takes a courtyard G on the south side of the subdivided land 101 in consideration of sunlight, and a living room, a dining room, and a kitchen (hereinafter, living room etc. L) are provided so as to face the courtyard G in consideration of lighting and ventilation. Also, in order to protect privacy in the living room etc. L space and the courtyard space, a privacy fence F is arranged at the boundary between the road 2 and the adjacent courtyard G for the house H on the north side, and for the house H on the south side, it is arranged so as to surround the entire courtyard G, thereby securing a private space.
[0004] As a method of protecting the privacy between adjacent detached houses, for example, in Patent Document 1, a method of providing a shared courtyard at the boundary between the two houses is described. Also, in Patent Document 2, a group of buildings is disclosed in which the courtyards of adjacent sections are arranged offset in the depth direction while sharing a part of the side along the boundary line of the adjacent land that divides the two sections.

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-070597 [Patent Document 2] Japanese Patent Publication No. 2019-078142 [Overview of the project] [Problems that the invention aims to solve]
[0006] However, the building complexes described in Patent Documents 1 and 2 all have problems with the cost and effort involved in construction, due to the complexity of the plot divisions and the structure and arrangement of the houses. Also, in the case of house H built on the subdivision 101 as shown in Figure 3, the garden G and living room L of house H on the north side may be completely visible from the adjacent house H on the south side. Furthermore, since the garden G of house H on the south side is surrounded by a fence F, if, for example, a tall privacy fence F is used, sunlight will be reduced, creating a feeling of confinement in the garden space. In addition, if the garden space is surrounded by many privacy fences F, it can create a feeling of oppression for the residents. On the other hand, the presence of privacy fences F makes it difficult to see what is happening from the outside, which can make the house more attractive to burglars and reduce security. Instead of using a privacy fence F, one could keep the curtains on the windows and doorways facing the garden G closed, but this would make the living room L a closed-off space, lacking a sense of openness.
[0007] Therefore, the present invention has been made in view of the above problems, and its objective is to provide a group of buildings that make it difficult to see inside the building from the outside, even without keeping curtains or the like closed all the time. [Means for solving the problem]
[0008] The above problems are solved by the building group of the present invention, in which, in each of two areas adjacent to each other in a first direction, two or more buildings are arranged side by side in a second direction intersecting the first direction, in the first direction, the buildings in one area are adjacent to the buildings in the other area, there are no windows located below the first height on the outer wall of one end of each building in the second direction, a garden is provided adjacent to the outer wall of the other end of each building in the second direction, and a partition wall is erected between the gardens of two adjacent buildings in the first direction.
[0009] In the group of buildings of the present invention configured as described above, the privacy of residents within the area can be protected with minimal facilities (partition walls). Specifically, it is possible to provide a group of buildings in which the interior of each building is difficult to see from the outside. Furthermore, since there is no need to close curtains, natural light can be brought in from the outside, making the interior of each building a bright and open space. In addition, the garden can be made into a private space, that is, a space where one can spend time without worrying about being seen by others.
[0010] Furthermore, in the above-mentioned group of buildings, it is preferable that a shielding wall is provided in the first direction, on the opposite side of the partition wall, adjacent to the garden. With the above configuration, it is possible to block views from outside the area without having to close curtains or anything similar.
[0011] Furthermore, in the above-mentioned group of buildings, it is preferable that windows are provided at a position lower than the second height on the outer wall at one end in the second direction. According to the above configuration, a building with a garden can have a private garden space because it is not exposed to the view of residents of the adjacent building with an exterior wall. In addition, living rooms and other rooms facing the garden can be open and airy, without the need for curtains. On the other hand, a building with an exterior wall can block the view from the garden side, while also improving natural light and ventilation.
[0012] Furthermore, in the above-mentioned building, it is preferable that the building be a single-story structure. According to the above configuration, the gardens located between adjacent buildings can receive more sunlight and ventilation, giving residents a sense of openness.
[0013] Furthermore, in the above-mentioned group of buildings, it is preferable that roads are located adjacent to the respective ends of the areas in the first and second directions. The above configuration makes it easy for vehicles to enter and exit each area.
[0014] Furthermore, in the above-mentioned group of buildings, it is preferable that each building in one area has a parking lot on the opposite side from the other area, and each building in the other area has a parking lot on the opposite side from the other area. According to the above configuration, the parking lot will be located adjacent to the building and garden, thus blocking views from outside the area with vehicles, etc.
[0015] Furthermore, in the above-mentioned group of buildings, it is preferable that the partition wall extends to a position where it reaches the area where the building diagonally opposite in the second direction is located. With the above configuration, it becomes possible to block the view from the building diagonally across the street with the minimum necessary equipment. [Effects of the Invention]
[0016] The present invention provides a group of buildings that make it difficult to see inside the buildings from the outside. [Brief explanation of the drawing]
[0017] [Figure 1] This is a schematic diagram showing an example of a group of buildings according to one embodiment of the present invention. [Figure 2] This is a schematic diagram showing a modified version of the building complex. [Figure 3] This is a schematic diagram showing an example of a conventional building complex. [Modes for carrying out the invention]
[0018] <<Regarding a building group according to an embodiment of the present invention>> Hereinafter, a building group according to one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the accompanying drawings. Here, the embodiment described below is merely an example for facilitating the understanding of the present invention and does not limit the present invention. That is, the present invention can be changed and improved without departing from its gist. Naturally, the present invention includes equivalents thereof. In the drawings, for the sake of easy understanding of the explanation, the structure of each member is simplified and illustrated in a schematic manner. Also, the sizes (dimensions) of each member shown in the drawings and the intervals between members are different from the actual ones.
[0019] In this specification, a "building group" refers to a plurality of buildings constructed on a partitioned land, and the plurality of buildings have similar sizes and structures to each other and are used for the purpose of human residence. In the following description, a house will be cited as an example of a building. However, the buildings of the present invention may be buildings other than houses, such as accommodation facilities, etc., as long as they have the same or similar functions as houses, specifically, buildings equipped with living rooms and the like. Also, in this specification, the partitioned land, buildings, and gardens are assumed to have the same, substantially the same, or symmetric shapes in the north-south direction or the east-west direction.
[0020] In the building group according to this embodiment, two or more buildings are arranged side by side in a second direction intersecting the first direction in each of two areas adjacent to each other in the first direction. In the first direction, the buildings in one area and the buildings in the other area are adjacent to each other. On the outer wall at one end side in the second direction of each building, there is no window provided at a position lower than a predetermined height (the first height). A garden is provided at a position adjacent to the outer wall at the other end side in the second direction of each building. A partition wall is erected between the gardens of two adjacent buildings in the first direction. For example, it is a housing group 1 as shown in FIG. 1.
[0021] As shown in Figure 1, the housing complex 1 consists of multiple houses H built on each of eight subdivided plots 3, which are created by dividing a single plot of land facing roads 2a to 2d on all four sides into one section in the east-west direction and three sections in the north-south direction. In two adjacent subdivided plots 3a and 3b, four houses H are arranged in a row in the north-south direction. Subdivided plots 3 are formed so that the longer sides face north-south and the shorter sides face east-west. Here, house H is a single-story structure, and as shown in Figure 1, the living room, dining room, and kitchen (hereinafter referred to as living room, etc. L) are located facing the garden G on the south side. Note that the floor plan of house H, which constitutes house group 1, is not particularly limited as long as the living room, etc. L is arranged along the garden G. Furthermore, the number of floors in the house H is not particularly limited as long as the living room, etc. L is arranged along the garden G, but if it is a single-story structure, there is no need to consider the amount of sunlight the adjacent house H or garden G on the north side receives.
[0022] Furthermore, in each house H, if the north exterior wall 4 faces the garden G of an adjacent house H in the north-south direction, no windows will be installed on that north exterior wall 4 at a position lower than a predetermined height (first height). Here, a position lower than a predetermined height is a position from which, in normal daily activities, the resident cannot look out the window, for example, a position lower than the height of an average adult.
[0023] Furthermore, in each house H, the south-facing exterior wall 5 faces the garden G. According to this embodiment, there is no need to block the boundary between the living room L and the garden G with curtains or the like, so the living room L and the garden G can be made into a continuous space with a visually expansive feel. As a result, the living room L can be made into an open interior space.
[0024] Furthermore, in the east-west direction, a privacy fence F1 is erected at the boundary between the gardens G1 of two adjacent houses H1 and G2 of house H2. The privacy fence F1 corresponds to the "partition wall" of the present invention. The height of the privacy fence F1 is such that it blocks the line of sight of the residents of the adjacent house H, for example, it can be about the height of an average adult.
[0025] Furthermore, the privacy fence F1 is installed to extend to the area where the diagonally opposite house H is located in the north-south direction (more precisely, the site on which the diagonally opposite house H is built). With this configuration, when considering houses H that are diagonally adjacent to each other, it is possible to block the view from the diagonally opposite garden G or house H. Specifically, in the case of the relative positions of houses H1 and H3, or houses H2 and H4, it is possible to make it difficult to see into the interior of house H2 or H4 from the garden G1 of house H1 through the window in the side wall 6b of house H3, or from the garden G2 of house H2 through the window in the side wall 6a of house H4. In addition, the garden G1 of house H1 or the garden G2 of house H2 can be made into a private space, that is, a space where one can spend time without worrying about being seen by others.
[0026] Furthermore, roads 2a to 2d are provided at the ends of each subdivision 3 in the east-west and north-south directions, and adjacent to them. Houses H1 and H6 to H8, located on one of the subdivisions 3a, which is divided into two plots in the east-west direction, have parking spaces P on their west side, while houses H2 to H5, located on the other subdivision 3b, have parking spaces P on their east side. Furthermore, the parking area P is positioned to face one end of the garden G located within the house H. Since the garden G is formed with longer sides on the north and south sides and shorter sides on the east and west sides, simply placing the parking area on the shorter side blocks the view from the road and makes the garden G a private space. Furthermore, if there are many people or vehicles using Road 2, a privacy fence F2 may be installed on houses H5 and H6, whose long side of garden G faces Road 2d.
[0027] According to the present invention, it is possible to provide a group of buildings in which the interior of the building is made difficult to see from the outside. Furthermore, because fewer privacy fences are installed in each house, it is possible to create a sense of openness in the garden space and in living rooms and other spaces facing the garden.
[0028] <<Regarding other embodiments>> Although one embodiment relating to the building group of the present invention has been described above, the above embodiment is merely an example to facilitate understanding of the present invention and does not limit it. In other words, the present invention can be modified and improved without departing from its spirit. Furthermore, it goes without saying that the present invention includes equivalents thereof. Furthermore, the present invention may be modified in the following ways.
[0029] (Variation 1) As shown in Figure 2, in the east-west direction, house H may have an additional privacy fence F3 installed on the opposite side of the privacy fence F1 installed between the gardens G of two adjacent houses H, and adjacent to the gardens G. Note that the privacy fence F3 corresponds to the "shielding wall" of the present invention. With the above configuration, it is possible to block views from outside the area without closing curtains or anything similar. Specifically, it is possible to create a garden G or indoor space that is more easily protected from the view of pedestrians and drivers passing on road 2.
[0030] (Modification 2) The north-facing exterior wall 4 of the adjacent house H in the north-south direction, which faces the garden G, may have windows positioned below a predetermined height (the second predetermined height). Here, a position below the predetermined height means a position where, in normal daily activities, the resident cannot look out the window, for example, a position lower than the knee height of a standard adult standing. According to the above configuration, the house H with the garden G is not exposed to the view of the residents of the house H with the adjacent north-facing exterior wall 4, thus making the garden G a private space. In addition, the living room L facing the garden G can also be an open interior space that does not require curtains. On the other hand, the house H with the north-facing exterior wall 4 can block the view from the garden G side, while also improving natural light and ventilation. [Explanation of symbols]
