Description

  The present invention relates to a house when the site is a narrow site or when houses are continuously arranged on the site.

When building a house on a narrow site, various ideas have been made to expand the living space and eliminate the feeling of pressure. For example, as a means for eliminating the feeling of pressure from neighboring houses and enabling daylighting, there is one in which the plane of the first floor portion is T-shaped. (For example, refer to Patent Document 1).
In addition, by installing the entrance at the entrance on the tangential side of the site, the entrance in the building tends to become an independent space, and the space in the building is shredded, and the hallway for moving between rooms is long. In order to prevent such a situation, there is a door provided with an entrance at a substantially central portion on either the left or right side wall surface along the depth direction. (For example, refer to Patent Document 2).
Japanese Patent Laid-Open No. 2000-136641 JP 2000-230324 A

When building a two-story house with as large a living space as possible on a narrow site, the construction is subject to restrictions such as building coverage, floor area ratio, height restrictions, north side diagonal lines, and lighting openings, but it is the most problematic. This is a limitation of the building coverage and the daylighting opening. Here, since it is common to have a parking lot in a house at present in the automobile society, the restriction of the opening ratio of the daylighting opening of the living room has become more problematic than the building coverage ratio.
In other words, even in the case of a house with a floor plan where living rooms that require daylighting are located on the second floor and bedrooms that are mainly used at night are located on the first floor, the boundary between the site boundary and the side wall of the building is required by law. The space had to be separated by a distance based on the daylighting of the living room on the first floor, and the site area could not be fully utilized.

In the example of FIG. 2 of Patent Document 1, in order to comply with the restrictions on the opening ratio of the daylighting opening of the living room and to bring the building side wall as close as possible to the three site boundaries other than the roadway side, A part of the building is cut out, and a terrace T is provided between the boundary of the site on the back side to secure the opening ratio of the first floor room. However, the terrace T thus provided cannot be accessed unless it passes through the first floor room, and items such as bicycles cannot be placed on the terrace T, and the method of use is extremely limited.
Moreover, in the example of FIG. 4 of patent document 1, since the terrace is not provided between the site boundary lines on the back side, in order to comply with the restrictions on the opening ratio of the lighting openings in the living room, It shows how a large space must be provided between the site boundary on the far side.
Such a space tends to become a pouch because the space between the right and left site boundaries along the depth direction and the side wall of the building is made as small as possible in order to obtain as large a living space as possible. You can't go without going through your room.
In such a space, the usage method is remarkably limited in the same manner as the terrace T described above.

In the example of FIG. 2 of Patent Document 2, by providing the entrance at a substantially central portion on either the left or right side wall surface along the depth direction, the space in the building is shredded, It prevents the corridors for moving between them from becoming long. However, in order to comply with the restrictions on the opening ratio of the daylighting openings in the living room, it is unavoidable that a large space must be provided between the building side wall surface and the site boundary line on the back side.
Therefore, an object of the present invention is to increase the living space by bringing the building side walls as close as possible to the boundary lines of the three sides other than the roadway side while complying with the restrictions on the opening ratio of the daylighting openings in the living room. At the same time, it is intended to provide a house with a courtyard that is highly convenient and can be used for multiple purposes with a high blindfold function from the outside without increasing the degree of freedom of floor plans and the feeling of pressure from neighboring houses.

  In order to solve the above-mentioned problem, the invention described in claim 1 includes a concave structure in which the central portion of either the left or right side wall surface along the depth direction is recessed as shown in FIG. Provide. And the entrance is provided on the side wall of the building along the depth direction of this courtyard, and the approach to the entrance along the depth direction is provided on the first floor of the protruding part on the side of the access road. It is characterized by providing a space for hygiene (toilet, toilet, bathroom, etc.) and stairs on the side wall side.

  According to the second aspect of the present invention, the floor of the balcony on the second floor is made of perforated material (grating, saw, etc.), and the veranda is placed on the second floor without impairing the daylighting opening of the first floor room. It is characterized by providing.

According to the first aspect of the present invention, by providing a courtyard substantially at the center, it is possible to light the living room on the back side without providing a large space between the side wall surface of the building and the site boundary line on the back side. It became possible to observe the restrictions on the opening ratio of the opening. In addition, by providing the entrance on the side wall of the building along the depth direction of the courtyard, the entrance is likely to become an independent space, so that the interior space of the building is shredded or moved between rooms. Can be prevented from becoming longer, and the living space can be expanded.
In addition, by providing a space and stairs for health and hygiene on the side wall opposite to the courtyard, the independence of the courtyard space is increased, and when a house is built in a continuous building or a neighboring house is approaching But privacy has become easier to protect.

In addition, by providing an approach to the entrance along the depth direction on the first floor of the protrusion on the side of the tangential surface, it is possible to reach the entrance from the tangential side without passing through the room. As a result, the range of use of the courtyard and approach has expanded, such as placing items such as bicycles in the courtyard and approach.
In addition, the approach can be expanded and used as a garage.

According to the second aspect of the present invention, the floor of the balcony on the second floor is made of a perforated material, and the second floor is maintained while complying with the restrictions on the opening ratio of the daylighting opening of the first floor living room. A veranda can be provided.
This allowed the living space on the second floor to be expanded.

  Hereinafter, the present invention will be described in detail with reference to the best mode. In addition, although the site | part shape is a rectangle and the case where a parking lot is provided in the tangential surface side is demonstrated here, this invention is not limited to this. The present invention can be applied even when the site shape is not rectangular, when a parking lot is not provided, or when a garage is provided by expanding the approach.

In this embodiment, a parking lot is provided on the side of the road boundary 1 that touches the road 1.
In the first embodiment, the courtyard 10 is provided by recessing the substantially central portion of the right wall surface in a concave shape. A window 13a is provided on the side of the courtyard 10 in order to comply with the restriction on the opening ratio of the daylighting opening of the living room provided in the rear projecting portion 13 of the building. Therefore, it is not necessary to provide a large space between the back side wall surface 9 of the building and the back side site boundary line 5.
Moreover, the entrance 11 is provided in the side wall surface of the building along the depth direction of the courtyard 10. And the approach 14 which leads to the courtyard 10 is provided in the approaching side protrusion 12 of the building. Therefore, it is not necessary to provide a large space between the right front wall surface 6, the right rear wall surface 7 and the right site boundary line 3 of the building.
Moreover, since the space 15 for health is concentrated on the left side of the building, it is not necessary to provide a large space between the left wall surface 8 and the left site boundary 4.
That is, the building is built close to the three directions on the far side and the left and right sides of the site boundary line, and the site area can be fully utilized.

  In addition, the entrance 11 is provided on the surface of the courtyard 10 along the depth direction, and the space 15 for health and sanitation, the stairs 16 and the like are concentrated on the left wall surface side of the building, thereby providing a living space in the building. However, the space such as the corridor can be reduced without being subdivided by these spaces.

  FIG. 3 is a plan view showing the floor plan of the second floor of the house according to the second embodiment of the present invention. In this embodiment, a balcony 17 is provided on the second floor of the house of the first embodiment. And since the balcony floor 18 is made of such a perforated material that facilitates the passage of light and wind, it can comply with the restrictions on the opening ratio of the daylighting opening of the first floor living room and can also reduce the living space. Can be spread.
