Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although various technically preferable limitations are imposed on the embodiments described below for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the directions in the following embodiments and illustrated examples are set merely for convenience of explanation.

[0015] In FIGS. 1 to 5, reference numeral 1 indicates a site which is a building lot. The site 1 includes a first site 1A on which a house 2 is built, a second site 1B which faces a road (not shown) and serves as a parking lot, and a third site 1C which extends from one end of the second site 1B toward the back (north side) in the depth direction of the site 1. The second site 1B is arranged adjacent to the south side of the first site 1A, and the third site 1C is arranged adjacent to the east side of the first site 1A. In other words, the second site 1B and the third site 1C are arranged so as to form an L shape in plan view, and the first site 1A is arranged at the inner corner portion of the second site 1B and the third site 1C formed in an L shape in plan view.

[0016] In the second site 1B, the portion along the south side edge located on the side opposite to the first site 1A is a road access surface 1D of the entire site 1. That is, the area south of the road access surface 1D is a road for people or vehicles to pass through. Therefore, the second site 1B is often used as a parking space. Note that a concrete slab is laid on the second site 1B. Also, the site 1 is in a state where a fence is provided at the peripheral portion.

[0017] The third site 1C is often used as a parking space, a bicycle parking space, etc. on the south side. A concrete slab is laid on the south side portion of the third site 1C. The north side of the third site 1C is used as, for example, a planting space, a home garden space, a storage space, a laundry drying space, etc., but is not particularly limited.

[0018] The house 2 of this embodiment is constructed by a panel method in which building components such as walls, floors, and roofs are pre-panelized at a factory and these panels are assembled at the construction site. However, it can also be applied to conventional buildings constructed by frame methods, wall methods, etc., such as wooden, steel frame, and reinforced concrete structures. In addition, a panel (wooden building panel) is one in which vertical and horizontal framing members are assembled in a rectangular shape, and auxiliary cross members are assembled vertically and horizontally inside the rectangular frame to form a frame body. A facing material such as plywood is attached to both sides or one side of this frame body, and it has an internal hollow structure. Furthermore, a heat insulating material such as glass wool or rock wool is loaded into the internal hollow part.

[0019] Also, as shown in FIGS. 1 to 4, such a house 2 includes a two-story house main body 3 built on a foundation and an inclined roof 7 provided on the house main body 3. The house main body 3 is formed longer in the north-south direction than in the east-west direction in plan view, and the inclined roof 7 is a welcoming roof formed long in the north-south direction like the house main body 3.

[0020] The inclined roof 7, which is a welcoming roof, includes a ridge part 7a extending in the east-west direction, a south roof surface 7b located on the south side of the ridge part 7a, and a north roof surface 7c located on the north side of the ridge part 7a. The south roof surface 7b and the north roof surface 7c have a 1 / 2 slope in this embodiment. That is, the south roof surface 7b and the north roof surface 7c are set at the same inclination angle.

[0021] The length of the south roof surface 7b in the roof runoff direction of the entire south roof surface 7b is set longer than the length of the north roof surface 7c in the roof runoff direction of the entire north roof surface 7c. The south roof surface 7b is formed in an L shape in plan view. That is, the south roof surface 7b has a portion with a long length to the eaves tip and a portion with a short length to the eaves tip. More specifically, the south roof surface 7b of the pitched roof 7 has a first roof portion 8 with a long length set from the ridge portion 7a to the first eaves tip portion 8a, and a second roof portion 9 with a short length set from the ridge portion 7a to the second eaves tip portion 9a. The first roof portion 8 and the second roof portion 9 are adjacent to each other and integrally formed to form the same roof surface 7b. That is, the south roof surface 7b is formed in a substantially L shape in plan view. And the first eaves tip portion 8a and the second eaves tip portion 9a are continuously connected in a crank shape via the keraba 8b which is the east end portion of the first roof portion 8. Note that the length from the ridge portion 7a to the second eaves tip portion 9a in the second roof portion 9 is set equal to the length from the ridge portion 7a to the north eaves tip portion in the north roof surface 7c.

[0022] On the upper surface of the south roof surface 7b, a solar cell array 10 having a plurality of solar cell modules is installed. The plurality of solar cell modules in the solar cell array 10 are also arranged in a substantially L shape in plan view in accordance with the shape of the south roof surface 7b. That is, in the south roof surface 7b, the first roof portion 8 has a larger area where solar cell modules can be installed because the length to the eaves tip (the first eaves tip portion 8a) is longer than that of the second roof portion 9.

[0023] As shown in FIGS. 5 and 6, the housing body 3 is generally divided into a west side portion 3a located directly below the first roof portion 8 as described above and an east side portion 3b located directly below the second roof portion 9 as described above. That is, the housing body 3 itself also has a shape corresponding to the dimensional difference between the length to the first eaves tip portion 8a and the length to the second eaves tip portion 9a in the south roof surface 7b. That is, the west side portion 3a located directly below the first roof portion 8 is formed longer in the north-south direction than the east side portion 3b located directly below the second roof portion 9.

[0024] Among the first building lots 1A on which such a house 2 is built, under the eaves of the first gable end 8a of the first gable roof 8, there is provided an outdoor living 11 as an outdoor space that is used as a place where residents usually stay, just like the indoor living room 23. The outdoor living 11 is provided from the south side surface of the west side portion 3a located directly below the first gable roof 8 of the house main body 3 to the vicinity of the south end of the first building lot 1A. In other words, the outdoor living 11 is provided so as to project toward the second building lot 1B side from the house main body 3.

[0025] The outdoor living 11 of the present embodiment is a terrace whose floor portion 11a is constituted by a plurality of deck materials. The height position of the upper surface (floor surface) of the floor portion 11a is set to be substantially equal to the floor surface of the first floor in the house main body 3. Also, a handrail 11b is provided at the south end of the outdoor living 11, and the upper end portion of this handrail 11b is constituted by a counter plate 11c. Residents can, for example, sit on a chair facing the counter plate 11c and perform various tasks, etc., and spend time in the outdoor living 11. Therefore, this outdoor living 11 is the most open space among the places where residents of the house 2 usually stay, and is used as a place with a high degree of publicity.

[0026] Also, among the first building lot 1A, under the eaves of the second gable end 9a of the second gable roof 9, a courtyard portion 12 is provided as a semi-outdoor space surrounded by a shielding wall 13 within the first building lot 1A. The courtyard portion 12 is in a state of being surrounded on all four sides by the east side surface of the west side portion 3a of the house main body 3, the south side surface of the east side portion 3b, and a shielding wall 13 formed in an L shape in plan view. The upper part of the courtyard portion 12 is open toward the sky except for the part where the inclined roof 7 is provided.

[0027] On the east side portion 3b of the housing main body 3, a front entrance 4b is provided facing the garden portion 12. More specifically, the outer wall 4 (i.e., the first outer wall 4) facing the south in the east side portion 3b has a wall surface extending across the upper and lower floors. And an opening is formed in a part of the first floor portion of the outer wall 4, and a front entrance 4b that is opened and closed by a front door is formed in the outer wall portion provided at the back of the opening. The garden portion 12 faces this front entrance 4b. That is, when going outside from the front entrance 4b, there is the garden portion 12 in that state, and the entrance 20 of the housing main body 3 and the garden portion 12 are directly connected. Note that the floor surface (porch floor) of the part from the front entrance 4b to the side of the garden portion 12 to the above-mentioned opening formed in a part of the first floor portion of the outer wall 4 is arranged one step higher than the floor surface of the part located outside the above-mentioned opening. In the garden portion 12, a ledge 12a is provided so as to project from the east side surface of the west side portion 3a. The height position of the upper surface of the ledge 12a is set to be substantially equal to the floor surface of the first floor in the housing main body 3.

[0028] The shielding wall 13 surrounding the garden portion 12 together with the east side surface and the south side surface of the housing main body 3 includes a first shielding wall 13a located on the south side, a second shielding wall 13b located on the west side, and a third shielding wall 13c located on the north side.

[0029] The first shielding wall 13a is arranged in parallel with the outer wall 4 (i.e., the first outer wall 4) facing the south in the east side portion 3b of the housing main body 3. Also, the first shielding wall 13a is arranged in parallel with or on the same straight line as the outer wall 5 (i.e., the second outer wall 5) facing the south in the west side portion 3a of the housing main body 3. Further, the first shielding wall 13a is arranged to be orthogonal in plan view with the outer wall 6 (i.e., the third outer wall 6) facing the east in the east side portion 3b of the housing main body 3. That is, as shown in FIGS. 1 to 3, the first shielding wall 13a is arranged so as to be visible side by side with the second outer wall 5 when viewed from the road side. Also, the height dimension of the first shielding wall 13a is set to be substantially equal to the height dimension of the second outer wall 5.

[0030] The second shielding wall 13b is arranged orthogonally to the first shielding wall 13a in plan view. More specifically, the east end of the first shielding wall 13a is connected to the south end of the second shielding wall 13b, and the second shielding wall 13b extends northward from the east end of the first shielding wall 13a in plan view. The north end of the second shielding wall 13b is located north of the building part 7a. This second shielding wall 13b is parallel to the third outer wall 6 and is arranged along the east side surface of the east side part 3b of the housing main body 3. Also, the height dimension of the second shielding wall 13b is set to be equal to the height dimension of the first shielding wall 13a. Note that the part of the second shielding wall 13b located north of the entrance and exit 4b functions as the outer wall of the housing main body 3. In other words, the part of the second shielding wall 13b located south of the entrance and exit 4b functions as the shielding wall 13.

[0031] The third shielding wall 13c is arranged orthogonally to the second shielding wall 13b in plan view and is arranged parallel to the first shielding wall 13a. More specifically, the north end of the second shielding wall 13b is connected to the east end of the third shielding wall 13c, and the third shielding wall 13c extends westward from the north end of the second shielding wall 13b in plan view. And the west end of the third shielding wall 13c is connected to the east side surface of the east side part 3b of the housing main body 3. Also, the height dimension of the third shielding wall 13c is set to be equal to the height dimension of the second shielding wall 13b. Note that this third shielding wall 13c functions as the outer wall of the housing main body 3.

[0032] In the first shielding wall 13a on the south side of the shielding wall 13 configured as described above, a gate 14 as an entrance and exit communicating the courtyard part 12 and the road side, a door leaf 14a for opening and closing the gate 14, and a delivery box 15 are provided. The gate 14 is arranged facing the entrance and exit 4b, and the delivery box 15 is provided beside the gate 14. The road side of the door 14 and the door leaf 14a is the entrance approach 1E that continues to the access road surface 1D across the south end of the first site 1A and the second site 1B. The entrance approach 1E extends along the east side of the outdoor living area 11 to the access road surface 1D. That is, the courtyard part 12 is located between the entrance and exit 4b of the housing main body 3 and the entrance approach 1E.

[0033] The courtyard part 12 can also be used to enter and exit the outside through the door 14, and since it is surrounded by the shielding wall 13, it is suitable as a place where, for example, children can play or the elderly can sit on the edge 12a and talk. Therefore, this courtyard part 12 is used as a place that is relatively open as a place where residents live their daily lives, has a high degree of publicity, and also has privacy that can effectively block the line of sight from the outside.

[0034] Next, with reference to FIGS. 5 to 8, the interior of the housing main body 3 will be described.

[0035] An entrance 20 is provided at the position passing through the entrance and exit 4b. The entrance 20 has an earthen floor part 20a with a floor surface approximately equal to the height of the above-mentioned porch floor, and an entrance hall part 20b at a position one step higher than the earthen floor part 20a. Note that the height position of the floor in the entrance hall part 20b is equal to the height position of the floor of the entire first floor. A shoe closet is provided on the north side of the earthen floor part 20a. Also, there is a fixed window 20c on the east side of the earthen floor part 20a, and the third site 1C can be seen. That is, this fixed window 20c is provided on the second shielding wall 13b. Note that the indoor side of the fixed window 20c is a sitting part.

[0036] The entrance hall part 20b also functions as a corridor extending in the north-south direction, and an entrance leading to the west part 3a of the housing main body 3 is provided on the west side of the south end. Also, a storage space is provided on the south side of the south end. A toilet 21 is provided on the east side at the north end of the entrance hall part 20b. That is, the toilet 21 is arranged on the north side of the entrance 20. On the west side at the north end of the entrance hall part 20b, a storage space 27a under the staircase 27 which will be described later is provided using the space under the staircase. On the north side at the north end of the entrance hall part 20b, an entrance is provided leading to a backyard zone equipped with a plurality of non-residential rooms 28, 29, 30 and a small room 31.

[0037] A living room 22 is provided in the west part 3a of the housing main body 3 at the end of passing through the entrance provided on the west side surface at the south end of the entrance hall part 20b. The living room 22 is a room in which the functions of a living room 23 (hereinafter referred to as the living 23), a dining room 24 (hereinafter referred to as the dining 24), and a kitchen 25 (hereinafter referred to as the kitchen 25) coexist in one room.

[0038] The living 23 (lower floor living room 23) is arranged at the south end of the west part 3a and is adjacent to the outdoor living 11 through the second outer wall 5 located on the south side. In other words, the second outer wall 5 is provided between the living 23 and the outdoor living 11. An opening 5a (third opening 5a) is formed in the second outer wall 5. The third opening 5a is a sweeping window formed at a height from the floor surface of the living room 22 to the vicinity of the upper end of the second outer wall 5. Also, this third opening 5a is set to an area occupying most of the second outer wall 5 and is a large opening. The outdoor living 11 is provided so as to project from the second outer wall 5, and it is possible to freely move between the living 23 and the outdoor living 11 through the third opening 5a.

[0039] The living room 23 is adjacent to the garden area 12 via the third outer wall 6 located on the east side at the south end of the west side portion 3a. In other words, the third outer wall 6 is provided between the living room 23 and the garden area 12. Since the third outer wall 6 constitutes the east side surface of the west side portion 3a of the housing main body 3, the upper end portion is formed obliquely in accordance with the inclination angle of the first roof portion 8. An opening 6a (the fourth opening 6a) is formed in the third outer wall 6. The fourth opening 6a is a sweeping window formed from the floor surface of the living room 22 to a height position approximately the same as that of the third opening 5a of the second outer wall 5. The edge platform 12a is provided so as to project from the third outer wall 6, and it is possible to freely move between the living room 23 and the edge platform 12a through the fourth opening 6a.

[0040] Note that the portion of the second outer wall 5 where the third opening 5a is formed is arranged to retreat inward from the south end surface of the west side portion 3a. In other words, the outer wall facing south in the west side portion 3a of the housing main body 3 has a wall surface extending from the foundation to the first roof portion 8. An opening is formed in a part of this outer wall, and the third opening 5a is formed in the outer wall portion provided at the back of the opening. Therefore, the outer walls provided on the left and right of the portion of the second outer wall 5 where the third opening 5a is formed extend southward. The outdoor living area 11 is provided between such left and right outer walls, and the area of the outdoor living area 11 is defined. Note that the outer wall located on the west side of the outdoor living area 11 is formed with a concave shape on the indoor side in plan view, and the inside thereof can be used as a storage space.

[0041] As shown in FIG. 7, the living room 23 is located directly below the first roof portion 8, and the upper space thereof is a through - blown gradient ceiling 23a up to the vicinity of the first roof portion 8. The lower end of the sloped ceiling 23a is arranged at a position higher than the second floor of the housing main body 3. The upper end of the sloped ceiling 23a is arranged at a height position substantially equal to the upper end of a partition wall 46a to be described later. And the inclination angle of the sloped ceiling 23a is set equal to the inclination angle of the first roof portion 8.

[0042] The dining area 24 and the kitchen 25 are arranged on the north side of the living room 23. A kitchen counter 25a is installed in the kitchen 25. The kitchen counter 25a is a peninsula kitchen that contacts the inner wall 26 on the backyard zone side. A dining table 24a is installed in the dining area 24. In this embodiment, the dining table 24a is provided adjacent to the kitchen counter 25a in the north-south direction, but it may be installed at a distance from the kitchen counter 25a.

[0043] A staircase 27 is provided in the living room 22. By arranging the staircase 27 in the living room 22 in this way, a so-called center living design can be realized. The center living refers to a floor plan where it is impossible to go to other floors without passing through the living room from the entrance. That is, also in the housing 2 of this embodiment, due to the arrangement of the staircase 27 in the living room 22, it has a floor plan where it is impossible to go to other floors without entering the living room 22 from the entrance 20. The staircase 27 of this embodiment is a straight staircase going up from the south to the north, and there is a below-stair storage portion 27a in the space below this staircase 27 as described above.

[0044] The north end of the first floor in the housing main body 3 is a backyard zone extending from the west side portion 3a to the east side portion 3b. The above-mentioned inner wall 26 is provided between the backyard zone and the entrance 20 and the living room 22. In other words, in the first floor of the housing main body 3, the north region partitioned by the inner wall 26 is the backyard zone. On the inner wall 26, there are formed an entrance 26a on the entrance hall part 20b side, an entrance 26b located between the kitchen counter 25a and the staircase 27, and an entrance 26c located on the west side of the kitchen counter 25a. Thereby, a circulation path can be formed around the dining table 24a and the kitchen counter 25a, and around the staircase 27. Note that each of the entrances 26a, 26b, and 26c is opened and closed by a fitting such as a door or a sliding door.

[0045] And as described above, the backyard zone includes a plurality of non-living rooms 28, 29, 30 and a small room 31. The non-living room 28 is a bathroom and is arranged on the easternmost side of the backyard zone. The non-living room 29 is a laundry room and is arranged adjacent to the west side of the non-living room 28 which is a bathroom. The non-living room 30 is a washroom and is arranged adjacent to the west side of the non-living room 29 which is a laundry room. The small room 31 is provided adjacent to the north end of the living room 22, and can communicate with the living room 22 through an entrance 26c (the third entrance 26c) formed on the inner wall 26 between the small room 31 and the living room 22. The plurality of non-living rooms 28, 29, 30 and the small room 31 are arranged side by side in the east-west direction, and the portion along the inner wall 26 can be used as a passage for going back and forth between each of the non-living rooms 28, 29, 30 and the small room 31. Also, fittings are appropriately provided on the passage. The above-mentioned entrances 26a, 26b, and 26c are provided facing the passage.

[0046] This small room 31 is a room located at the position farthest from the outdoor living 11 in the west side part 3a of the housing main body 3, and the entrance 26c between the small room 31 and the kitchen 25 can also be blocked by a fitting. Therefore, the small room 31 is suitable as a place where residents doing housework in the kitchen 25 or the non-living rooms 28, 29, 30 can take a rest or carry out housework while doing telework. Therefore, this yard part 12 is the most closed space as a place where residents spend their daily lives and is used as a place with high privacy. In the small room 31, at least a seating part 31a for the resident to sit is provided so that the resident can spend a comfortable time in the small room 31. In this embodiment, a work counter 31b is provided so that telework can also be performed.

[0047] Subsequently, when going up the stairs 27, there is the second floor of the housing main body 3. The floors of the second floor are all at the same height position. At the end of going up the stairs 27, first, a first corridor 40 extending in the east-west direction is provided. In addition, a second corridor 41 that intersects the west end of the first corridor 40 in a plan view and extends in the north-south direction is provided. Further, the second corridor 41 is arranged along the stairs 27. The first corridor 40 and the second corridor 41 are formed in a substantially L shape by being arranged perpendicular to each other. In addition, a toilet 42 is provided on the north side of the first corridor 40. An entrance with fittings is provided between the first corridor 40 and the toilet 42.

[0048] A first bedroom 43 is provided on the east side of the stairs 27 and the first corridor 40. An entrance with fittings is provided between the east end of the first corridor 40 and the first bedroom 43. This first bedroom 43 is a place where the resident spends daily life and can be used as a so-called master bedroom. The first bedroom 43 is located in the east part 3b of the housing main body 3 and is provided directly below the second roof part 9 of the south roof surface 7b and the north roof surface 4c.

[0049] A second bedroom 44 is provided on the west side of the first corridor 40 and the second corridor 41. An entrance with fittings is provided between the west end of the first corridor 40 and the second bedroom 44. This second bedroom 44 is a place where the resident spends daily life and can be used as a so-called bedroom (children's room). The second bedroom 44 is located in the west part 3a of the housing main body 3 and is provided directly below the first roof part 8 of the south roof surface 7b and the north roof surface 4c.

[0050] On the south side of the second corridor 41 and the second bedroom 44, a first room 46 is provided and used as a multi-purpose space (multi-commons) shared among the residents. An entrance with furniture is provided between the south end of the second corridor 41 and the first room 46. The first room 46 is located directly below the first roof portion 8 and is arranged adjacent to the upper space of the living room 23 on the first floor in the north-south direction. Therefore, a partition wall 46a facing the upper space of the living room 23 is provided on the south side of the first room 46. The partition wall 46a is arranged parallel to the second outer wall 5 in plan view and is arranged perpendicular to the third outer wall 6.

[0051] A first opening 46b that communicates the first room 46 with the upper space is formed in the partition wall 46a. The first opening 46b is formed at a height from the floor surface of the first room 46 to the vicinity of the upper end of the partition wall 46a and has a plurality of small openings formed by vertical and horizontal battens. These plurality of small openings are made to be fixed windows, but are not limited thereto and may be openable windows. Further, the lower end of the first opening 46b may be a waist-high window located at about the height of a person's waist (for example, about 80 to 100 cm from the floor).

[0052] When looking horizontally southward from the first opening 46b, the sloping ceiling 23a of the living room 23 comes into view. Also, as shown in FIG. 8 and the like, when looking obliquely downward southward from the first opening 46b, the living room 23, the third opening 5a formed in the second outer wall 5, and the outdoor living 11 on the outdoor side of the third opening 5a come into view. Further, when looking obliquely downward southeastward from the first opening 46b, the living room 23, the fourth opening 6a formed in the third outer wall 6, and the garden portion 12 (including the edge stand 12a) on the outdoor side of the fourth opening 6a come into view. The first room 46 is equipped with desks and chairs and is located on the second floor, making it a suitable space for work such as telecommuting. Since the first floor and the outdoor space are visible from the first opening 46b as described above, while working or performing duties in the first room 46, the resident can look through the first opening 46b by directing their line of sight towards it, enabling them to peek at the situation on the first floor and the outdoor space.

[0053] The ceiling of the first room 46 is divided into a horizontal ceiling portion and a sloped ceiling portion with the position of the dashed line L1 shown in Fig. 6 as the boundary. As shown in Fig. 7, the sloped ceiling of the first room 46 is arranged on the same straight line as the sloped ceiling 23a of the living room 23. In other words, it is in a state where a partition wall 46a is provided in the middle part of the sloped ceiling 23a that continues from the first floor to the second floor.

[0054] At the east end of the first room 46 and on the south side of the staircase 27 is a passage 46c. The passage 46c is arranged adjacent to the second room 47 located on the south side of the first bedroom 43. An entrance with fittings is provided between the passage 46c and the second room 47. Note that the south side of the passage 46c is a storage space using a wall formed in a concave shape in plan view.

[0055] The second room 47 is arranged adjacent to the south side of the first bedroom 43. That is, it is arranged in the east part 3b of the housing main body 3 and is located directly below the second roof portion 9. Such a second room 47 has an outer wall 4 (first outer wall 4) facing the outdoor space, and an opening 4a (second opening 4a) that communicates the second room 47 with the outdoor space is formed in the outer wall 4. In other words, the second room 47 is provided at the south end of the east part 3b in the housing main body 3. Since the second opening 4a is located above the shielding wall 13, it faces the upper space of the courtyard portion 12. Note that the second opening 4a is formed at a height from the floor surface of the second room 47 to the vicinity of the upper end of the outer wall 4, and has a plurality of small openings formed by being partitioned vertically and horizontally. These plurality of small openings are blind windows, but are not limited thereto, and may be windows that can be opened and closed.

[0056] A sliding door 47a configured to be openable and closable is provided between the first bedroom 43 and the second room 47. Therefore, if the sliding door 47a is opened, the first bedroom 43 and the second room 47 are in a spatially continuous state. In other words, the first bedroom 43 and the second room 47 are one room without an entrance, and such one room is partitioned by the sliding door 47a. In the present embodiment, the sliding door 47a is used to partition the first bedroom 43 and the second room 47, but is not limited thereto, and a partitioning device that is configured to be storable along the wall and is deployed from the storage location may be used.

[0057] The second room 47 is mainly a small room that is used as a multi-purpose space (multi-nook) by the resident who uses the first bedroom 43 and the resident who uses the first room 46. The second room 47 is used, for example, as a laundry drying space, a rest space, etc., but is not particularly limited. A resident who uses the first room 46 as a work space such as telecommuting can use the second room 47 as a rest space, check on the children playing in the garden section 12, or perform laundry drying work.

[0058] Since the second opening 4a is located above the shielding wall 13, when the line of sight is directed horizontally southward from the second opening 4a, the road comes into view. Also, when the line of sight is directed obliquely downward southward from the second opening 4a, the courtyard section 12 and the gate 14 come into view. If the door leaf 14a has a transparent configuration, the entrance approach 1E outside the gate 14 also comes into view. Furthermore, since the second opening 4a is arranged orthogonally to the fourth opening 6a in plan view, when the line of sight is directed southwestward from the second opening 4a, the living room 23 comes into view through the fourth opening 6a. Therefore, the resident in the second room 47 can peek at the state of the first floor and the outdoor space through the second opening 4a by directing the line of sight to the second opening 4a while working or resting in the second room 47.

[0059] According to the present embodiment, the following excellent effects can be obtained. That is, among the first roof section 8 and the second roof section 9 that form the same roof surface 7b of the sloping roof 7, the first eaves section 8a of the first roof section 8 can be made longer than the second eaves section 9a of the second roof section 9, so that the area of the roof 7 can be widened accordingly. Thereby, for example, a wider area where a power generation device such as the solar cell array 10 can be installed can be secured, contributing to the realization of a highly environmentally friendly dwelling. Moreover, the living room 23 is located directly below the first roof section 8, and its upper space penetrates near the first roof section 8 to form a sloping ceiling 23a. Therefore, for example, when the ceiling height is set to the height of the total second floor and compared with the case of a horizontal ceiling, the sense of volume can be reduced. Thereby, the air conditioning efficiency in the living room 23 can be improved, contributing to the realization of a highly environmentally friendly dwelling. Further, the first room 46 located directly below the first roof portion 8 has a partition wall 46a facing the upper space of the living room 23, and a first opening 46b that communicates the first room 46 with the upper space is formed in the partition wall 46a. Therefore, the line of sight can pass between the first room 46 and the living room 23. Further, the second room 47 located directly below the second roof portion 9 has a first outer wall 4 facing the outdoor space, and a second opening 4a that communicates the second room 47 with the outdoor space is formed in the first outer wall 4. Therefore, the line of sight can pass between the second room 47 and the outdoor space. Therefore, the resident on the upper floor can peek at the state of the living room 23 or the outdoor space from the first room 46 or the second room 47 while staying in the first room 46 or the second room 47. The resident on the lower floor can peek at the state of the first room 46 or the second room 47 from the living room 23 or the outdoor space while staying in the living room 23 or the outdoor space. Thereby, it is possible to secure a spatial connection in which the family's line of sight passes between the upper and lower floors.

[0060] Further, since the first outer wall 4 is arranged in the same direction as the partition wall 46a, the living room 23 visible from the first opening 46b and the outdoor space visible from the second opening 4a are necessarily arranged in the same direction. Therefore, it becomes easy to make the living room 23 and the outdoor space have a spatial connection. In the house 2 or the site 1 where the house 2 is built, it becomes easy to form a space where residents tend to gather in the direction in which the living room 23 visible from the first opening 46b and the outdoor space visible from the second opening 4a are arranged. Thereby, it becomes easier for the resident on the lower floor to come into view from the first room 46 or the second room 47, and it becomes easier to secure a spatial connection in which the family's line of sight passes between the upper and lower floors.

[0061] In addition, since the first room 46 and the second room 47 are arranged adjacent to each other, the living room 23 visible from the first opening 46b and the outdoor space visible from the second opening 4a will necessarily be arranged adjacent to each other. Therefore, it becomes easier to make the living room 23 and the outdoor space have a spatial connection. Among the house 2 or the site 1 on which the house 2 is built, it becomes easier to form a space where residents tend to gather at the location where the living room 23 visible from the first opening 46b and the outdoor space visible from the second opening 4a are arranged. As a result, it becomes easier for the residents downstairs to come into view from the first room 46 or the second room 47, so it becomes easier to ensure a spatial connection such that the family's line of sight passes between the upper and lower floors.

[0062] In addition, since the upper edge of the first opening 46b is located near the sloped ceiling 23b and the lower edge is located near the floor of the first room 46, it is possible to ensure a long vertical dimension of the first opening 46b. Therefore, it becomes easier for the line of sight to pass between the first room 46 and the living room 23, so it becomes easier to ensure a spatial connection such that the family's line of sight passes between the upper and lower floors.

[0063] In addition, when the first opening 46b is a waist-high window whose upper edge is located near the sloped ceiling 23a and whose lower edge is located above the floor of the first room 46, it is possible to limit to some extent the ease of passing of the line of sight between the first room 46 and the living room 23, which is preferable because it can contribute to privacy protection between the upper and lower floors.

[0064] In addition, an outdoor living area 11, which is an outdoor space allowing access to the living room 23 through a third opening 5a formed in the second outer wall 5 between the living room 23, is provided adjacent to the outdoor side of the end of the living room 23 on the side of the first gable end 8a. Therefore, a line of sight can pass between the first room 46 and the outdoor living area 11 through the first opening 46b, the living room 23, and the third opening 5a. Accordingly, a resident on the upper floor can peek at the state of the living room 23 and the outdoor living area 11 from the first room 46 while staying in the first room 46. A resident in the outdoor living area 11 can peek at the state of the living room 23 and the first room 46 from the outdoor living area 11 while staying in the outdoor living area 11. Thereby, a spatial connection can be secured such that the family's line of sight passes between the upper and lower floors and between the indoor and outdoor areas.

[0065] In addition, since the inclined roof 7 is provided with a power generation device 10, if the power generation device 10 is a power generation device that utilizes renewable energy such as a solar cell array 10, etc., it can contribute to realizing a house with high environmental performance.

[0066] Moreover, the outdoor space facing the first outer wall 4 has a courtyard 12 surrounded by a shielding wall 13 within the site 1. The living room 23 has a third outer wall 6 facing the courtyard 12, and a fourth opening 6a communicating the living room 23 and the courtyard 12 is formed in the third outer wall 6. Therefore, a line of sight can pass between the living room 23 and the courtyard 12 through the fourth opening 6a. Thereby, a spatial connection can be secured such that the family's line of sight passes between the indoor and outdoor areas. Moreover, if, for example, the first opening 46b or the second opening 4a is arranged at a position visible from the fourth opening 6a, a spatial connection can be secured such that the family's line of sight passes between the upper and lower floors and between the indoor and outdoor areas through the fourth opening 6a. Furthermore, since the courtyard 12 is surrounded by the shielding wall 13 within the site 1, it is difficult to be seen from outside the site 1 and is easy to be seen from the second opening 4a. Therefore, the courtyard 12 has high security and is suitable as a space for children to play, for example.

[0067] In addition, the courtyard portion 12 is located between the entrance doorway 4b of the housing main body 3 and the entrance approach 1E. On the portion of the shielding wall 13 on the entrance approach 1E side, a gate 14, a gate leaf 14a for opening and closing the gate 14, and a delivery box 15 are provided. Therefore, from the second opening 4a, it is possible to peek at the state of people entering and leaving the gate 14 and the state of storing luggage in the delivery box 15.

[0068] In addition, since the second opening 4a and the fourth opening 6a are arranged in directions orthogonal to each other in plan view, a line of sight will pass between the second opening 4a on the upper floor side and the fourth opening 6a on the lower floor side. Thereby, through the second opening 4a and the fourth opening 6a, it is possible to secure a spatial connection such that the family's line of sight passes between the upper and lower floors and between the indoor and outdoor spaces.

[0069] Also, a living room 23, an outdoor living area 11 as an outdoor space provided adjacent to the outdoor side of the south surface at the south end of the living room 23 and allowing passage to and from the living room 23 through a third opening 5a formed in a second outer wall 5 between the living room 23 and the outdoor living area 11, a garden area 12 as a semi-outdoor space provided adjacent to the outdoor side of the east surface at the south end of the living room 23 and allowing passage to and from the living room 23 through a fourth opening 6a formed in a third outer wall 6 between the living room 23 and the garden area 12 and surrounded by a shielding wall 13 within the site 1, and a small room 31 as an indoor space provided adjacent to the north surface at the north end of the living room 23 and allowing passage to and from the living room 23 through an entrance / exit 26c formed in an inner wall 26 which is a partition wall between the living room 23 and the small room 31 are provided. Since the south end of the living room 23 is arranged on the side of the access road surface 1D in the site 1, the outdoor living area 11 is arranged closest to the road, the garden area 12 is arranged close to the road but shielded by the shielding wall 13, and the small room 31 is arranged farthest from the road. Thus, when the resident lives with the living room 23 as the center, in addition to the option of spending time in the living room 23, the resident can choose an arbitrary place from the options of spending time in the highly public outdoor living area 11, the garden area 12 having both public and private properties, and the highly private small room 31. Therefore, the variety of ways of spending time with the living room 23 as the center can be enriched, and the comfort in living with the living room 23 as the center can be improved.

[0070] In addition, the outdoor living area 11 has a floor portion 11a that projects from the outer surface of the housing main body 3 and a handrail 11b disposed at the leading end of the floor portion 11a in the projecting direction. Since the upper end portion of the handrail 11b is constituted by a counter plate 11c, the position of the handrail 11b is arranged at a position farther from the housing main body 3. That is, it will be arranged on the side closer to the road. Therefore, when working or the like on the counter plate 11c, the work will be carried out in an open space. Thus, for the residents, the outdoor living area 11 is recognized as the most open space among the living areas in the house 2 as a place where the residents spend their daily lives and as a place with a high degree of publicity, and can contribute to enriching the variations in the way of living centered around the living room 23.

[0071] In addition, the access road surface 1D is located outside the outdoor living area 11, and further includes a porch approach 1E provided between the portion of the shielding wall 13 on the access road surface 1D side and the outdoor living area 11 passing through the side of the outdoor living area 11 to the access road surface 1D. Therefore, it is possible to pass through the porch approach 1E while peeping at the state of the outdoor living area 11. Conversely, it is also possible to confirm a person passing through the porch approach 1E from the outdoor living area 11. Therefore, the security of the house 2 can be improved.

[0072] In addition, at least a seat portion 31a for a person to sit is installed in the small room 31, so that the comfort when spending time in the small room 31 can be improved.

[0073] In recent years, the realization of a decarbonized society by promoting carbon neutrality with substantially zero carbon dioxide emissions and the achievement of the goals of SDGs (Sustainable Development Goals) have been demanded. Also in the construction industry, efforts have been made to make buildings wooden structures with low carbon dioxide emissions. Since the house 2 of this embodiment is a wooden single-family house, it can contribute to the realization of a decarbonized society by promoting carbon neutrality and the achievement of the goals of SDGs.

Note that a toilet 92 is provided on the north side of the first corridor 40.

[0091] On the east side of the stairs 77 and the first corridor 90, a first bedroom 93 (second room) is provided. An entrance with fittings is provided between the east end of the first corridor 90 and the first bedroom 93. This first bedroom 93 is a place where the resident spends daily life and can be used as a so-called master bedroom.

[0092] On the west side of the first corridor 90, a second bedroom 94 is provided. An entrance with fittings is provided between the west end of the first corridor 90 and the second bedroom 94. This second bedroom 94 is a place where the resident spends daily life and can be used as a so-called bedroom (children's room).

[0093] On the west side of the southern part in the second corridor 91, a third bedroom 95 located south of the second bedroom 94 is provided. An entrance with fittings is provided between the second corridor 91 and the third bedroom 95. This third bedroom 95 is a place where the resident spends daily life and can be used as a so-called bedroom (children's room). The third bedroom 95 is located directly below the first roof portion 8 and is arranged adjacent to the upper space of the living room 73 on the first floor in the north-south direction. Therefore, a second partition wall 95a facing the upper space of the living room 73 is provided on the south side of the third bedroom 95. An opening 95b that communicates the third bedroom 95 with the upper space is formed in the second partition wall 95a.

[0094] On the south side of the south end of the second corridor 91, a first room 96 is provided, which is located on the east side of the third bedroom 95 and is used as a multi-purpose space (multi-commons) shared by the residents. An entrance with fittings is provided between the south end of the second corridor 91 and the first room 96. The first room 96 is located directly below the first roof portion 8 and is arranged adjacent to the upper space of the living room 73 on the first floor in the north-south direction. Therefore, a first partition wall 96a facing the upper space of the living room 73 is provided on the south side of the first room 96. The first partition wall 96a is arranged parallel to the second outer wall 55 in plan view and is arranged perpendicular to the third outer wall 56. A first opening 96b that communicates the first room 96 with the upper space is formed in the first partition wall 96a.

[0095] The second partition wall 95a of the third bedroom 95 and the first partition wall 96a of the first room 96 are arranged on the same straight line. Also, the opening 95b formed in the second partition wall 95a and the first opening 96b formed in the first partition wall 96a are arranged side by side in the east-west direction. When looking horizontally southward from these openings 95b and the first opening 96b, the sloped ceiling of the living room 73 will come into view. Also, when looking diagonally downward southward from the openings 95b and the first opening 96b, the living room 73, the third opening 55a formed in the second outer wall 55, and the outdoor living room 61 on the outdoor side of the third opening 55a will come into view. Furthermore, when looking diagonally downward southeastward from the openings 95b and the first opening 96b, the living room 73, the fourth opening 56a formed in the third outer wall 56, and the outdoor side (a part of the entrance approach 51E) of the fourth opening 56a will come into view. Since desks are installed in the third bedroom 95 and the first room 96 and they are provided on the second floor, they are suitable spaces for performing various tasks such as telework. And since the first floor and the outdoor space can be seen from the openings 95b and the first opening 96b as described above, the residents can peek at the situation of the first floor and the outdoor space through the openings 95b and the first opening 96b by looking at the openings 95b and the first opening 96b while working or performing duties in the third bedroom 95 and the first room 96.

[0096] The first bedroom 93 is provided on the east side of the first room 96. An entrance with furniture is provided between the first room 96 and the first bedroom 93. The first bedroom 93 has an outer wall 54 (the first outer wall 54) facing the outdoor space, and an opening 54a (the second opening 54a) that communicates the first bedroom 93 and the outdoor space is formed in the outer wall 54. In other words, the first bedroom 93 is provided in the east side portion 53b of the housing main body 53. Note that the lower end of the second opening 54a is a waist-high window located above the floor surface of the first bedroom 93.

[0097] The southern end of the first bedroom 93 is used as, for example, a laundry drying space, a rest space, etc., but is not particularly limited. A resident who uses the first room 96 as a work space for telecommuting or the like can use the southern end of the first bedroom 93 as a rest space to check on children playing outside or to perform laundry drying work.

[0098] When looking horizontally southward from the second opening 54a, the road comes into view. Also, when looking diagonally downward southward from the second opening 54a, the entrance approach 51E comes into view. Furthermore, since the second opening 54a is arranged orthogonally to the fourth opening 56a in plan view, when looking southwestward from the second opening 54a, the living room 73 comes into view through the fourth opening 56a. Therefore, a resident in the first bedroom 93 can peek at the first floor and the outdoor space through the second opening 54a by directing their line of sight towards the second opening 54a while working or resting in the first bedroom 93.

[0099] According to this modified example, among the first roof portion 8 and the second roof portion 9 that form the same roof surface 7b of the pitched roof 7, the first eaves portion 8a of the first roof portion 8 can be made longer than the second eaves portion 9a of the second roof portion 9, so that the area of the roof 7 can be widened accordingly. As a result, for example, a wider area can be secured for installing a power generation device such as a solar cell array 10, contributing to the realization of a highly environmentally performant dwelling. Moreover, the living room 73 is located directly below the first roof portion 8, and its upper space penetrates near the first roof portion 8 to form a sloped ceiling. Therefore, for example, when the ceiling height is set to the height of two floors in total and compared to the case of a horizontal ceiling, it is possible to reduce the sense of volume. This can improve the air conditioning efficiency in the living room 73, contributing to the realization of a highly environmentally performant dwelling. Further, the first room 96 located directly below the first roof portion 8 has a partition wall 96a facing the upper space of the living room 73, and a first opening 96b communicating the first room 96 and the upper space is formed in the partition wall 96a. Therefore, the line of sight can pass between the first room 96 and the living room 73. Further, the first bedroom 93 located directly below the second roof portion 9 has a first outer wall 54 facing the outdoor space, and a second opening 54a communicating the first bedroom 93 and the outdoor space is formed in the first outer wall 54. Therefore, the line of sight can pass between the first bedroom 93 and the outdoor space. Therefore, the resident on the upper floor can peek at the state of the living room 73 or the outdoor space from the first room 96 or the first bedroom 93 while staying in the first room 96 or the first bedroom 93. The resident on the lower floor can peek at the state of the first room 96 or the first bedroom 93 from the living room 73 or the outdoor space while staying in the living room 73 or the outdoor space. Thereby, a spatial connection can be ensured such that the line of sight of the family passes between the upper and lower floors.

[0100] 〔Modification Example 2〕 The house 2 in the above-described embodiment is a two-story house, but the house in this modification example is a three-story house. In that case, the roof balcony in the second floor portion of the house is used as the outdoor living room 11. Further, the courtyard portion 12 whose line of sight from the outside is blocked by the shielding wall 13 may be on the same floor as the outdoor living room 11 or on the ground floor.

[0101] According to this modification example, even if the house 2 has three or more stories, the same effects as those of the above-described embodiment are exhibited.
