[0127] <9. Entrance to a house in the northern part of the building> The entrances to the northern house (360) and the southern house (60) differ in the following respects, but are identical in all other respects.

[0128] In the southern house 60, the south-facing wall of the entrance hall 73 is the third exterior wall 63. In contrast, in the northern house 360, the south-facing wall 463 of the entrance hall 73 is a partition wall. The first floor portion of this wall 463 separates the toilet room 379 from the entrance hall 373, and the second floor portion of this wall 463 separates the open space above the entrance hall 373 from the living room 389.

[0129] In the northern house 360, an opening leading from the entrance hall 373 to the corridor 378 is formed in the south-facing wall 463 of the entrance hall 73. In contrast, in the southern house 60, no such opening is provided in the third exterior wall 6.

[0130] In the southern house 60, the sink 118 and faucet 119 are installed on the countertop 117, closer to the decorative wall 113. In contrast, in the northern house 360, the sink and faucet of the washbasin 416 are installed on the countertop, closer to the partition wall.

[0131] In house 60 to the south, mirror 120 is positioned south of window 121. In contrast, in house 360 ​​to the north, mirror is positioned north of window 421.

[0132] In the southern house 60, an opening 101c and a door are provided in the west wall 100 of the entrance hall 73, allowing movement between the entrance hall 73 and the living room / dining room / kitchen (LDK) 75 through the opening 101c and door. In contrast, in the northern house 360, no such opening or door is provided in the west wall 400 of the entrance hall 73.

[0133] In the southern house 60, the pipe space 123 is installed above the decorative ceiling 112, close to the wall 103. In contrast, the northern house 360 ​​does not have such a pipe space.

[0134] Furthermore, the window 421, high window 422, and washbasin 416 installed in the entrance of the northern house 360 ​​correspond to the window 121, high window 122, and washbasin 116 installed in the entrance of the southern house 60, respectively.

[0135] <10. Summary> (1) Because the overhanging slab 24 extends from the upper end of the retaining wall 22 toward the slope 2, even if the house 60 is built closer to the retaining wall 22, a large outdoor space such as a garden is formed on the elevated area above the overhanging slab 24. Residents can enter the outdoor space above the overhanging slab 24 and have a view toward the slope 2 from that outdoor space. Since the house 60 can be built closer to the retaining wall 22, the house 60 also has a view toward the slope 2.

[0136] (2) The line of sight from the slope 2 toward the house 60 is blocked by the overhang floor slab 24 and the rising section 25, so that the privacy inside the house 60 is protected by the overhang floor slab 24 and the rising section 25.

[0137] (3) Because the base slab 23 extends from the lower end of the retaining wall 22 toward the slope 2, the base slab 23 does not easily interfere with the construction of the house 60, columnar bodies 51 and foundation 52. Therefore, the house 60, columnar bodies 51 and foundation 52 can be constructed closer to the retaining wall 22. Even if the house 60 is constructed closer to the retaining wall 22, the overhanging floor slab 24 provides a wide outdoor space on the elevated ground above it.

[0138] (4) Because the base slab 23 extends from the lower end of the retaining wall 22 toward the opposite side of the slope 2, the retaining wall 22 is stabilized and its safety is improved. The length by which the base slab 23 extends from the lower end of the retaining wall 22 toward the slope 2 is longer than the length by which the base slab 23 extends toward the opposite side of the slope 2 from the lower end of the retaining wall 22, so that the stability of the retaining wall 22 is ensured, and the base slab 23 does not hinder the construction of the house 60, foundation 52 and columnar body 51 toward the retaining wall 22.

[0139] (5) As multiple columnar bodies 51 reinforce the ground on the high ground, the foundation 52 and house 60 built on top of them are constructed stably. Since the base slab 23 extends from the lower end of the retaining wall 22 toward the slope 2, the base slab 23 does not easily hinder the construction of the columnar bodies 51. Therefore, the columnar bodies 51, foundation 52 and house 60 can be constructed closer to the retaining wall 22. Even if the house 60 is constructed closer to the retaining wall 22, the overhanging floor slab 24 provides a wide outdoor space on the high ground above it.

[0140] (6) The balcony 98 is installed adjacent to the first exterior wall 61. When the house 60 is constructed closer to the retaining wall 22, the railing wall 99a of the balcony 98 is parallel to the retaining wall 22 and the rising section 25, so that the railing wall 99a, the retaining wall 22 and the rising section 25 appear to be arranged in an orderly manner. This enhances the aesthetic design of the building 10.

[0141] (7) Because the handrail wall 99a and the rising section 25 are the same color, the handrail wall 99a and the rising section 25 appear to be arranged in an orderly manner. This enhances the aesthetic design of the building 10.

[0142] (8) The fence 32 helps to prevent people in the outdoor space above the overhanging deck 24 from falling.

[0143] (9) If the railing wall 99a is low, the railing can be erected on top of the railing wall 99a. Since the railing is a glass railing and the fence 32 is a glass fence, the fence 32 and the railing are arranged in an orderly manner, and these fences 32 and railings make the railing wall 99a and the rising section 25 appear to be arranged in an orderly manner. This enhances the aesthetic design of the building 10.

[0144] (10) The decorative ceiling 112 extends from the underside of the earthen floor ceiling 104 towards the space between the hall floor 108 and the hall floor 108, and the washbasin 116 is installed below the protruding portion of the decorative ceiling 112, so that the washbasin 116 is positioned in the flow of movement when returning home or going out. In other words, when returning home, residents can move from the entrance earthen floor 71 to the entrance hall 73 and immediately wash their hands at the washbasin 116. When going out, residents can get ready at the washbasin 116 and then immediately move from the entrance hall 73 to the entrance earthen floor 71.

[0145] (11) Since the decorative ceiling 112 is located above the washbasin 116, it is easier for residents to concentrate on washing their hands or getting ready at the washbasin 116. Since the decorative ceiling 112 blocks the view from above the entrance hall 73, the privacy of those who wash their hands or get ready at the washbasin 116 is ensured.

[0146] (12) The entrance hall 73 is open because it extends from the hall floor 108 to the open ceiling 110. The entrance hall 73 is even more open because it is spatially continuous with the area above the decorative ceiling 112. Because the open ceiling 110 is higher than the floor ceiling 104 above the floor 107, when looking up from the entrance floor 71 towards the upper part of the entrance hall 73, the line of sight is blocked by the floor ceiling 104, and the line of sight is easily drawn to the space that extends upward beyond the floor ceiling 104. For this reason, the openness of the entrance hall 73 is particularly striking.

[0147] (13) The entrance area 71 is open because a portion of it is open from the hall floor 108 to the floor 107 and then to the open ceiling 110. The entrance area 71 is even more open because it is spatially continuous with the area above the decorative ceiling 112.

[0148] (14) The partition wall 114 divides the space below the decorative ceiling 112 into the area on the earthen floor 107 and the area on the hall floor 108, and the washbasin 116 is installed in the area on the hall floor 108. As a result, when looking from the entrance earthen floor 71 towards the entrance hall 73, the line of sight is blocked by the partition wall 114. Therefore, the privacy of the person performing tasks such as washing hands or getting ready at the washbasin 116 is ensured.

[0149] (15) Since the storage door 115 is located in the area north of the partition wall 114 within the space below the decorative ceiling 112, that area can be used as storage space. Since the earthen floor 107 extends to the area north of the partition wall 114 within the space below the decorative ceiling 112, that area can be used as a shoe closet 72.

[0150] (16) The decorative wall 113 is attached to the third exterior wall 63 on the south side of the entrance hall 73, and the decorative wall 113 is erected below the edge of the decorative ceiling 112, so that the decorative wall 113, as a structural element, highlights the decorative ceiling 112. These decorative walls 113 and decorative ceiling 112 contribute to improving the aesthetic design of the entrance.

[0151] (17) The open space above the entrance hall 73 is connected to the central hall 91 by an opening 101b in the wall 100, making the entrance hall 73 feel spacious.

[0152] (18) The decorative ceiling 112 blocks the line of sight from the central hall 91 to the washbasin 116, thereby ensuring the privacy of those who wash their hands or get ready at the washbasin 116.

[0153] (19) The second exterior wall 62 is erected opposite the wall 100, and the high window 122 is installed on the second floor of the second exterior wall 62 opposite the opening 101b. This high window 122 contributes to lighting the entrance hall 73 and the central hall 91.

[0154] (20) Window 121 is installed on the first floor of the second exterior wall 62. Window 121 contributes to lighting around the washbasin 116.

[0155] (21) A pendant light fixture 130 is suspended from the open ceiling 110. The pendant light fixture 130 contributes to the lighting of the entrance hall 73, the entrance floor 71, and the central hall 91.

[0156] (22) The energy used from the production to the disposal of timber is less than the energy used from the production to the disposal of metal or concrete materials. Therefore, if 60,360 houses are made of wood, 60,360 houses contribute to the realization of a decarbonized society by promoting carbon neutrality, which effectively reduces carbon dioxide emissions to zero, and to the achievement of the Sustainable Development Goals (SDGs).
