Description

[Technical Field]

[0001] The present invention relates to a residential building, and more particularly to a residential building having a down-floor structure and pit living. [Background technology]

[0002] In recent years, various residential buildings have been proposed that have a pit living space with a down-floor structure that provides a step between the pit living space and the normal main floor (see, for example, Patent Document 1 and Patent Document 2). In residential buildings with a pit living space, the pit living space is loosely enclosed by side walls that are at a different height from the normal main floor, and the ceiling feels high, providing a sense of security and openness, creating a comfortable, relaxing space. However, it is believed that the quality of residential buildings can be further improved by providing a living space that not only provides an even greater sense of openness but also has a soothing effect.

The children's room 29 and the Western-style room 30 can be accessed from the living-dining-kitchen 28. A flat balcony 31 is provided south of the Western-style room 30, located in the southwest corner of the residential building 50, at the top of a tower-shaped portion 32 (see Figure 1) on the west side of the flat balcony 31, detached from the main roof 12, so as to form the ceiling slab of the master bedroom 27 on the first floor 51.

[0021] A Western-style room 33 is provided to the east of the living / dining / kitchen room 28, located on the south side of the main staircase 25. The Western-style room 33 is provided along the east wall of the second floor 52, occupying an area that extends into the attic space 34 adjacent to the east side of the open-ceiling space 10 in the attic part of the main roof 12.

[0022] In this embodiment, an open-ceiling space 10, which is a key part of the present invention, is provided in the central part of the south side of the residential building 50, as shown in Figures 3 to 7, and is located directly below the sloped ceiling 13 of the main roof 12 of the residential building 50, and is a rectangular area when viewed from above. As described above, the atrium space 10 has a glass window 15 attached to the interior / exterior partition 14 between the indoors and outdoors, which is formed along the lower end 12a of the main roof 12, and a pit living room 11 having a floor surface 11a lower than the main floor surface 51a of the first floor 51 is provided adjacent to the interior side of the glass window 15.In the atrium space 10, an open staircase 17 is installed along one of the side partition wall surfaces 16 that is perpendicular to the interior / exterior partition surface 14 to which the glass window 15 is attached, and which divides the atrium space 10.The open staircase 17 is installed diagonally from an access floor 18 at the same floor height as the main floor 21 of the first floor, which is located at the corner between the one side partition wall surface 16 and the interior / exterior partition surface 14, towards the second floor 52, and the area between the pit living room 11 and one of the side partition wall surfaces 16, including the area below the open staircase 18, is a planting space 19.

[0023] In this embodiment, the pit living room 11, which constitutes the open-ceiling space 10, has a down-floor structure with a floor surface 11a that is lower than the main floor surface 51a of the first floor 51, for example, the dining kitchen 24, by a height difference of approximately 360 to 400 mm. The pit living room 11 occupies a rectangular area, for example, approximately 12 to 15 tatami mats in size. The pit living room 11 can be placed, for example, along the north edge adjacent to the dining kitchen 24 and the west edge adjacent to the planting space 19, with a sofa in the northwest corner and a table in the center. In addition, a first step board 11b is provided adjacent to the east side of the sofa on the north edge of the pit living room 11, at a height that is half the height difference between the main floor surface 51a of the first floor 51 and the floor surface 11a of the pit living room 11 (see Figure 6). This allows residents to move easily and smoothly between the dining kitchen 24 and the pit living room 11. On the west side of the pit living room 11, a second step board 11c is provided, with the area adjacent to the south side of the sofa used as a passageway, installed at a height that is half the difference in height between the main floor surface 51a of the first floor 51 and the floor surface of the pit living room 11 (see Figure 6). This allows residents to move easily and smoothly between the pit living room 11 and the lift floor 18 provided at the corner of one side partition wall surface 16 and the interior / exterior partition surface 14, and between the lift floor 18 and the master bedroom 27 adjacent to it on the west side.

[0024] In addition, in this embodiment, the entire space above the pit living room 11 is an open-ceiling space that reaches the sloped ceiling 13 on the underside of the main roof 12. This, combined with the fact that the floor surface 11a of the pit living room 11 is a down-floor structure that is lower than the main floor surface 51a of the dining kitchen 24, for example, makes it easier for residents relaxing in the pit living room 11 to sense the expansion of the space, especially in the vertical direction, and allows them to feel an even more open feeling.

[0025] The planting space 19 that constitutes the atrium space 10 is located adjacent to the west side of the pit living room 11, and is a rectangular area in plan view that includes the area directly below the open staircase 18, which is located adjacent to the second step board 11c and the north side of the lift floor 18. The planting space 19 can be formed to have a floor surface that is continuous with the floor surface 11a of the pit living room 11, for example. Preferably, planters or the like are placed in the planting space 19, and by piling up planting soil inside the planting space and planting various trees and plants, the planting space 19 can be greened.

[0026] As a result, for example, a resident relaxing in the pit living room 11 can see the trees and plants planted in the planting space 19 between one of the side partition walls 16, allowing them to feel the greenery while indoors and achieving a soothing effect. In particular, in this embodiment, the space above the planting space 19 is open up to the sloped ceiling 13, making it possible to plant tall trees and plants, enhancing the soothing effect of greening. Furthermore, because the green planting space 19 is provided to include the area below the open staircase 18, the area where soil can be piled up is wide, making it possible to maintain a good environment for plant growth.

[0027] In this embodiment, glass windows 15 are attached, preferably over almost the entire surface, to the interior / exterior partition 14 formed along the lower end 12a of the main roof 12 in the atrium space 10. This opens up the view to the outdoors, making it easier to sense the spaciousness of the space, and creating a sense of openness.

[0028] Furthermore, in this embodiment, an open staircase 17 with treads preferably made of wood is installed along one side partition wall surface 16 in the atrium space 10 that is perpendicular to the interior / exterior partition surface 14 to which the glass window 15 is attached, from an access floor 18 at the same floor height as the main floor 21 on the first floor to the second floor 52 at an angle. This enhances the wood-like feel and makes it possible to increase the soothing effect that natural materials have.

[0029] As a result, the residential building 50 of this embodiment makes it possible to obtain an even more open feeling through the pit living room 11, and also to obtain a living space that can bring about a healing effect, thereby further improving the quality.

[0030] Furthermore, in the residential building 50 of this embodiment, a stepped floor 36 of the same height as the main floor surface 51a of the first floor 51 is installed along the interior / exterior partition surface 14 to which the glass window 15 is attached in the open-ceiling space 10, and is provided between the pit living room 11 and the stepped floor 36 with a width of, for example, about 360 to 400 mm (see FIG. 6). This makes it possible to communicate with the resident sitting on the sofa in the pit living room 11 while sitting by the window, and to feel the greenery outside and enjoy an even more open feeling.

[0031] Furthermore, in the residential building 50 of this embodiment, it is preferable that a deck floor 37 of the same height as the main floor surface 51a of the first floor 51 is provided on the outdoor side of the interior / exterior partition surface 14 to which the glass window 15 is attached in the open-ceiling space 10, extending along the interior / exterior partition surface 14 (see FIG. 5). This makes it easy to go from indoors to outdoors via the deck floor 37, which is connected at the same height as the stepped floor 36 on the indoor side.

[0032] Furthermore, in the residential building 50 of this embodiment, it is preferable that the interior surface of the sloped ceiling 13 in the open-ceiling space 10 be provided with louver decorative material 35, which is formed by arranging multiple louver boards 35a, preferably made of wood, in parallel and extending in the direction of the gradient (see Figs. 5 and 7). This not only enhances the woody feel, enhancing the soothing effect, but also provides a sound-absorbing effect.

[0033] In the residential building 50 of this embodiment, a vertical lattice decorative material 38, preferably formed by arranging multiple vertical boards 38a, preferably made of wood, in parallel, is preferably provided on one side partition wall surface 16 perpendicular to the interior / exterior partition surface 14 in the open-ceiling space 10 (see FIGS. 5 and 6). This not only enhances the wood-like feel and enhances the soothing effect, but also provides a sound-absorbing effect. In this embodiment, a sliding door 16a that allows access to the master bedroom 27 is provided on the south side of one side partition wall surface 16 perpendicular to the interior / exterior partition surface 14, facing the lift-up floor section 18 (see FIG. 4). The vertical lattice decorative material 38 is provided on substantially the entire one side partition wall surface 16, including the area of ​​the door 16a.

[0034] Furthermore, in this embodiment, the treads of the open staircase 17, the louver boards 35a of the louver decorative material 35, and the vertical boards 38a of the vertical lattice decorative material 38 are preferably made of wooden materials, so by making extensive use of wooden materials, it is possible to further enhance the soothing effect brought about by natural materials.

[0035] The present invention is not limited to the above-described embodiment and can be modified in various ways. For example, the main roof and open-ceiling space of a residential building do not necessarily have to be arranged facing the south side of the building, but may be arranged facing other directions, such as the east or west side. The residential building does not necessarily have to be a two-story building, but may be a three-story or higher building. For example, the present invention can be applied with the third floor as the upper floor and the second floor as the lower floor. The treads of an open staircase, the louver boards of a louvered decorative material, and the vertical boards of a vertical lattice decorative material may be made of materials other than wood.
