[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-070599 Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, as people are spending more time at home due to the expansion of telecommuting, there has been a rise in demand for outdoor activities that can be done in the garden, such as DIY and gardening. In addition, there has been a rise in interest in ideas and methods for enjoying the outdoors, such as using the garden as an extension of the living room, camping in the garden, and having barbecues in the garden. However, despite this growing demand for outdoor activities, it is said that in recent years the number of extremely hot days (temperatures of 35°C or higher) has increased due to the effects of global warming. As a result, measures such as simply covering part of the garden with a canopy make it difficult to carry out outdoor work comfortably on hot summer days, and it is also difficult to casually enjoy the feeling of being outdoors.

[0005] The present invention has been made in consideration of the above circumstances, and its object is to enable work that would normally be done outdoors to be performed comfortably indoors, and to enable the outdoor atmosphere to be easily enjoyed indoors. [Means for solving the problem]

[0006] The invention described in claim 1 is a building 1, and as shown in, for example, FIGS. 1 to 3, an inner terrace section 21 is provided on the indoor side of an outer wall 6 (2, 3, 4) provided on the periphery of the building 1, and a ceiling is provided above the inner terrace section 21. The inner terrace section 21 is disposed adjacent to a room 28 in the building 1 via a partition wall 22. and a front porch portion 20 disposed adjacent to the inner terrace portion 21 inside the building on the outdoor side via the outer wall 6. It is equipped with The exterior wall 6 is formed with an outdoor opening 6a that connects the front porch portion 20 and the inner terrace portion 21, and is provided with a fitting 6b that opens and closes the outdoor opening 6a. The inner terrace portion 21 has an entrance floor portion 23a and work space portions 24, 25 adjacent to and continuous with the entrance floor portion 23a, The floor surface of the inner terrace portion 21 and the floor surface of the front porch portion 20 is composed of 12 earthen floors, The floor level of the front porch section 20 and the floor level of the inner terrace section 21 are set to be approximately the same. The height position of the lower end of the outdoor opening 6a is set to be approximately equal to the height positions of the floor surfaces of the front porch portion 20 and the inner terrace portion 21, The partition wall 22 is characterized in that it has an indoor opening 22a that connects the room 28 with the inner terrace portion 21, and is provided with a fitting 22b that opens and closes the indoor opening 22a.

[0007] According to the invention described in claim 1, the inner terrace section 21 is provided on the indoor side of the exterior wall 6 (2, 3, 4) and has a ceiling above it, so that it is provided as an indoor space in the building 1. Therefore, the inner terrace section 21 is easily recognized as an indoor space of the building 1 by people inside the building 1. On the other hand, the inner terrace section 21 has a dirt floor 12 and is separated from the room 28 by a partition wall 22 and fittings 22b that open and close the indoor opening 22a. Furthermore, the inner terrace section 21 can easily connect to the outdoor space by opening the outdoor opening 6a of the exterior wall 6. This makes it easy for people inside the building 1 to recognize it as an outdoor space. The inner terrace section 21 also includes an entrance dirt floor 23a, which is closest to the outdoor space, and work spaces 24 and 25 adjacent to and continuous with the entrance dirt floor 23a, which serve as work spaces separate from the entrance. This makes it easy for people inside the building 1 to recognize that work that would not normally be performed indoors can only be performed in the inner terrace section 21 (work spaces 24 and 25). In other words, the inner terrace section 21 is easily recognized as an indoor space in which the psychological barrier of performing work that should normally be performed outdoors indoors is somewhat lowered. This allows people inside the building 1 to easily do outdoor work or enjoy the feeling of being outdoors on the inner terrace section 21. Furthermore, if the outdoor opening 6a is closed with the fittings 6b, the inner terrace section 21 is separated from the outdoor space and has an environment similar to that of an indoor space, so outdoor work can be done comfortably even on a hot summer day. Also, if it is not a hot summer day, the outdoor opening 6a can be left open, allowing outdoor work to be done comfortably in an open environment.

[0008] The invention described in claim 2 is, for example, as shown in FIG. 2, in the building 1 described in claim 1, The work space section 24 (first work space section 24) is characterized by having a work table 24a installed therein.

[0009] According to the invention described in claim 2, the work space section 24 is provided with the work table 24a, which makes it easier for people in the building 1 to recognize the work space section 24 as a space different from the entrance floor section 23a. In addition, when working in the work space section 24, the work table 24a can be used to perform various tasks, making it easy to use.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 1 and 2, in the building 1 described in claim 1, The room 28 has an opening 4a that is configured to be openable and closable and that connects the room 28 to the outdoors, The opening 4a, the outdoor opening 6a, and the indoor opening 22a of the room 28 are arranged in a straight line.

[0011] According to the invention recited in claim 3, the opening 4a, outdoor opening 6a, and indoor opening 22a of room 28 are arranged in a straight line, so that openings 4a, 6a, and 22a can be opened to allow air to pass from the outdoor space on the inner terrace 21 side to the outdoor space on the room 28 side. This allows for efficient ventilation of the inner terrace 21 and living room 28, improving the comfort of the indoor environment in the inner terrace 21 and room 28, especially unless it is a hot summer day.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 1 and 2, in the building 1 described in claim 3, The inner terrace portion 21 and the room 28 are arranged along the north side of the perimeter of the building 1, The opening 4a, the outdoor opening 6a, and the indoor opening 22a of the room 28 are characterized by being arranged on a straight line along the east-west direction.

[0013] According to the invention recited in claim 4, the opening 4a, the outdoor opening 6a, and the indoor opening 22a of the room 28 are arranged in a straight line along the east-west direction, so that openings 4a, 6a, and 22a can be opened to allow air to pass through the building 1 in the east-west direction. Furthermore, the inner terrace 21 and the room 28 are arranged along the north side of the perimeter of the building 1, so air can pass through the building 1 in the east-west direction from the north side, where the temperature is relatively lower than that of the south side, further improving the comfort of the indoor environment in the inner terrace 21 and the room 28.

[0014] The invention described in claim 5 is, for example, as shown in Figs. 1 to 3, in the building 1 described in claim 1, The balcony 16 is provided above the outdoor opening 6a and extends outward. The exterior wall 6 in which the outdoor opening 6a is formed is characterized in that it is located closer to the interior than the tip end (balustrade wall 17) of the upward protruding portion 16 in the protruding direction.

[0015] According to the invention described in claim 5, the exterior wall 6 in which the outdoor opening 6a is formed is positioned closer to the interior than the tip of the upward protrusion 16 in the protrusion direction, so sunlight is blocked by the upward protrusion 16, making it difficult for sunlight to penetrate into the inner terrace 21. This improves the comfort of the indoor environment in the inner terrace 21, especially during the daytime in summer.

[0016] The invention described in claim 6 is, for example, as shown in FIG. 2, in the building 1 described in claim 1, The entrance floor section 23a and the work space sections 24, 25 are arranged side by side in a first direction in a plan view, The entrance floor portion 23a is characterized in that it is formed to extend in a second direction perpendicular to the first direction in a plan view.

[0017] According to the invention described in claim 6, the entrance floor 23a and the work spaces 24, 25 are arranged side by side in a first direction in a plan view, and the entrance floor 23a is formed to extend in a second direction perpendicular to the first direction in a plan view, so that people who enter the building 1 from the entrance can be guided in either the first direction or the second direction. This makes it possible to ensure at least two traffic lines from the entrance 23 to the back, and each traffic line can be used selectively as needed, making it easy to use.

[0018] The invention described in claim 7 is, for example, as shown in FIG. 2, in the building 1 described in any one of claims 1 to 6, The entrance floor section 23a is located adjacent to passages 23b, 26 (entrance hall section 23b, first floor corridor 26) which are formed in a different direction from the work space sections 24, 25, and the passages 23b, 26 are connected to the room 28, allowing access thereto.

[0019] According to the invention described in claim 7, the entrance floor 23a is disposed adjacent to the passages 23b, 26 formed in a different direction from the work spaces 24, 25, and the passages 23b, 26 are connected to the room 28 for easy access, so that people entering the building 1 from the entrance can be guided to either the work spaces 24, 25 or the passages 23b, 26. This ensures that at least two traffic lines can be secured from the entrance 23 to the room 28, and each traffic line can be used as needed, making it easy to use. [Effects of the Invention]

[0020] According to the present invention, work that would normally be done outdoors can be comfortably done indoors, and the outdoor feeling can be easily enjoyed indoors. [Brief explanation of the drawings]

[0021] [Figure 1] This is a perspective view showing the front part of the building. [Figure 2] This is a plan view showing the first floor of the building. [Figure 3] This is a plan view showing the second floor of the building. DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, although the embodiments described below are subject to various technically preferable limitations for carrying out the present invention, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0023] As shown in FIGS. 1 to 3, the building 1 of this embodiment is a west-facing house with few openings on the north and south sides and with the main openings used for lighting on the west side. The north-side exterior wall 2 and south-side exterior wall 3 of the building 1 are so high that they protrude above the second floor 14 from the foundation, but the height of the parts that protrude above the second floor 14 is set low. In other words, the height is set to be approximately the same as the handrail wall 17 of the balcony 16.

[0024] The roof is a gable roof, with a north roof 8 provided at the top end of the north exterior wall 2 and a south roof 9 provided at the top end of the south exterior wall 3. Although the roof in this embodiment is a gable roof, it is a steeply sloped roof, just like a gassho-style roof, and the attic space under such a roof forms the second floor of the building 1. The type of roof is not limited to a gable roof, but it is assumed to be a roof that has an exposed gable surface like a gable roof and allows the attic space to be used as living space. Furthermore, since the second floor of building 1 is formed below the steeply sloping north roof 8 and south roof 9, the ceiling is a sloped ceiling that utilizes the underside of north roof 8 and south roof 9, and the ceiling height decreases as you move towards the north and south.

[0025] The first east-side exterior wall 4 is an exterior wall on the first floor located on the east side, and the second east-side exterior wall 5 is an exterior wall on the second floor located on the east side. The upper side of the second east-side exterior wall 5 is formed in a triangular shape along the north-side roof 8 and the south-side roof 9. The first east-side exterior wall 4 and the second east-side exterior wall 5 are exterior walls that are provided along the same vertical plane. The first east-side exterior wall 4 and the second east-side exterior wall 5 are provided across the eastern ends of the north-side exterior wall 2 and the south-side exterior wall 3 .

[0026] The first west exterior wall 6 is an exterior wall on the first floor located on the west side, and the second west exterior wall 7 is an exterior wall on the second floor located on the west side. The first west exterior wall 6 and the second west exterior wall 7 are not arranged along the same vertical plane. The first western exterior wall 6 has a portion where a large outdoor opening 6a is formed, a portion that is concave in plan cross section (the first concave space S1 portion), and a portion where an entrance / exit 6c is formed, and forms the outdoor side of the inner terrace portion 21 described later. The upper side of the west-side second exterior wall 7 faces the balcony 16, and is formed in a triangular shape along the north-side roof 8 and south-side roof 9. Furthermore, this west-side second exterior wall 7 is positioned closer to the interior side (east side) than the west-side first exterior wall 6. In other words, because it is positioned further back inside the room than the west-side first exterior wall 6, the eaves of the north-side roof 8 and south-side roof 9 are correspondingly deeper. The balcony 16 is provided below these deep eaves portions 8a, 9a.

[0027] The perimeter of building 1 is roughly formed as described above. Other configurations of the perimeter of building 1 include the following: The western end faces of the north roof 8 and south roof 9 are flush with the western end faces of the north exterior wall 2 and south exterior wall 3. In addition, the eastern end faces of the north roof 8 and south roof 9 are flush with the eastern end faces of the north exterior wall 2 and south exterior wall 3. Also, solar battery panels (not shown) are provided over substantially the entire surface of the south roof 9. On the other hand, skylights (not shown) are provided on the north roof 8. Furthermore, one window 2a is formed on the first floor in the north exterior wall 2, and one window 3a is formed in the stairwell 33 in the south exterior wall 3. In other words, there are very few openings formed in the north exterior wall 2 and the south exterior wall 3. This makes it possible to prevent strong sunlight from entering the building as much as possible in the summer, and to suppress the cold draft phenomenon in the winter.

[0028] The first floor of the building 1 consists of an outdoor earthen floor 11, an indoor earthen floor 12, and an indoor first floor floor 13. The outdoor earthen floor 11 is located at a position up the outdoor staircase 10 from the ground and is an earthen floor located on the outdoor side of the first west exterior wall 6. The indoor earthen floor 12 is an earthen floor located on the indoor side of the west side first exterior wall 6. The outdoor earthen floor 11 and the indoor earthen floor 12 are set to approximately the same floor level, but it is desirable that the outdoor earthen floor 11 and the indoor earthen floor 12 have a water gradient formed toward the outdoors. Furthermore, although not shown, it is even more desirable that the outdoor earthen floor 11 and the indoor earthen floor 12 are equipped with drainage equipment below the finished floor surface that discharges water outdoors or into a drainpipe. The first floor interior floor 13 constitutes the floors of each room provided in the first floor interior, and the floors of each room are formed flat. Furthermore, flooring material is used as the floor finish. The floor level of this first floor interior floor 13 is one step higher than the outdoor earthen floor 11 and the indoor earthen floor 12. The difference in floor level (height of the step) is, for example, 18 to 20 cm, but is not limited to this and may be, for example, about 10 cm or less. The interior of the first floor of the building 1 refers to each room provided on the first floor interior floor 13 or the entire area in which the rooms are provided, and does not include the inner terrace portion 21.

[0029] The second floor of the building 1 consists of a second floor interior floor 14 and a balcony floor 15. The second floor interior floor 14 constitutes the floors of each room on the second floor, and each room has a flat floor. Furthermore, flooring material is used as the floor finish. The balcony floor 15 is a dirt floor located on the outdoor side of the west-side second exterior wall 7. The space between the balcony floor 15 and the eaves portions 8a, 9a of the north-side roof 8 and the south-side roof 9 is a balcony 16. A balustrade wall 17 is provided at the west end of the balcony floor 15. In this embodiment, the second floor interior floor 14 and the balcony floor 15 are set to be at approximately the same floor level, but the balcony floor 15 may be located lower. The balcony floor 15 is also provided with a water gradient and is equipped with drainage facilities such as drains and gutters. Furthermore, the term "indoors" as used herein refers to each room provided on the second floor indoor floor 14 or the entire area in which each room is provided, and does not include the balcony 16.

[0030] Next, the layout of the building 1 will be described. A front porch section 20 having an outdoor earthen floor 11 as its floor surface is provided on the outdoor side of the first western exterior wall 6 of the building 1. The front porch section 20 is provided between the north-side exterior wall 2 and the south-side exterior wall 3. The southern portion of the front porch 20 functions as a front entrance porch. This front entrance porch is provided with a storage area 20a, which can store items such as umbrellas, next to the entrance door 6c formed in the first west exterior wall 6.

[0031] An inner terrace section 21, with the indoor earthen floor 12 as the floor surface, is provided on the indoor side of the west-side first exterior wall 6. Similar to the front porch section 20, the inner terrace section 21 is provided between the north-side exterior wall 2 and the south-side exterior wall 3. The inner terrace section 21 is separated from the indoor side (living room 28) by an indoor-side partition wall 22. The inner terrace section 21 is also provided on the indoor side of the west-side first exterior wall 6, and is separated from the outdoors by this west-side first exterior wall 6. Furthermore, the inner terrace section 21 always has a ceiling or roof above it. In other words, it does not open directly to the sky above. However, the roof may have an openable skylight, chimney, ventilation tower, etc. In this embodiment, there is a ceiling and a roof above the inner terrace section 21. Above the ceiling are the balcony 16, rooms 38, and second-floor corridor 34, which are part of the second floor of the building 1. The inner terrace section 21 is a room located indoors, but is intended for work that would normally be done outdoors or work that is preferably done outdoors (outdoors) (hereinafter referred to as outdoor work), and is recognized as an intermediate area (buffer area) between the outdoor space and indoor rooms. Here, outdoor work includes DIY, gardening, camping with camping gear, barbecues, bicycle and machine maintenance, etc. It can also refer to painting, crafts, sculpting, sewing, etc. In other words, it refers to all work that is done outdoors to avoid getting the indoors dirty.

[0032] The inner terrace section 21 comprises an entrance 23 located indoors through the entrance doorway 6c, a first work space section 24 located north of the entrance 23, and a second work space section 25 located north of the first work space section 24. The entrance 23, the first work space 24, and the second work space 25 are provided on the same indoor earthen floor 12 and are a continuous space without any separation. Therefore, although the first work space 24 and the second work space 25 are described as separate spaces in this embodiment, they may also be the same space.

[0033] The entrance 23 has an entrance dirt floor section 23a, the floor surface of which is the indoor dirt floor 12, and an entrance hall section 23b, which is adjacent to the entrance dirt floor section 23a and located on the indoor side. The floor surface of the entrance hall section 23b is the first floor indoor floor 13. Here, the inner terrace portion 21 includes only the entrance earthen floor portion 23a of the entrance 23, which has the indoor earthen floor 12 as the floor surface. The entrance floor section 23a extends from the entrance doorway 6c to the staircase room 33 (described later) and is elongated in the depth direction perpendicular to the width direction. However, this is not limiting, and the entrance floor section 23a may extend from the entrance doorway 6c to an extension of the interior partition wall 22.

[0034] On the north side of the entrance hall 23b, an entrance storage section 23c is provided, which includes a wall that is perpendicular to the indoor partition wall 22. The entrance 23 is an open-ceiling section with an open upper space that extends all the way up to the south roof 9. However, although the entrance 23 has an open upper space in this embodiment, it does not have to be an open space. In other words, there may be a ceiling above the entrance 23.

[0035] The first work space 24 refers to the area located between the first recessed space S1 formed in the west side first exterior wall 6 as a concave space in a plan cross section and the second recessed space S2 formed in the indoor partition wall 22 as a concave space in a plan cross section. A workbench 24a and a chair 24b are installed in the first recessed space S1, and outdoor work can be done while sitting on the chair 24b. The second recessed space S2 is divided into left and right storage sections 24c and 24d, which can store machines, tools, materials, etc. necessary for outdoor work carried out in the inner terrace section 21. The space between the first recessed space S1 and the second recessed space S2 serves as a work space and passageway, connecting the entrance 23 and the second work space portion 25.

[0036] The second work space section 25 is a space where tables, benches, etc. can be set up to relax or where camping equipment can be spread out, and a larger work space than the first work space section 24 can be secured. The second work space 25 is located between an outdoor opening 6 a formed in the west-side first exterior wall 6 and an indoor opening 22 a formed in the indoor partition wall 22 .

[0037] The outdoor opening 6a is opened and closed by a folding door 6b. The folding door 6b allows the outdoor opening 6a to be opened widely. The folding door 6b is provided with a translucent material such as glass on the shoji screen, allowing sunlight to enter from outside and allowing the outdoor scenery to be seen.

[0038] The indoor opening 22a is opened and closed by two sliding doors 22b. Because they are sliding doors 22b, when the indoor opening 22a is opened, they do not protrude toward the second working space 25 or the inside of the room, unlike folding doors. The sliding door 22b is made of a translucent material such as glass, allowing sunlight to enter from outside and allowing views of the first work space 24, the second work space 25, and the outdoors.

[0039] When the outdoor opening 6a and the indoor opening 22a are opened at the same time, the outdoor space and the indoor space (living room 28) can be connected to each other.

[0040] The inner terrace 21, which includes the entrance 23, first work space 24, and second work space 25, is located outside the indoor partition wall 22, but is located inside the west first exterior wall 6. In other words, the inner terrace 21 is strictly an indoor space. Therefore, the inner terrace 21 has a different configuration from a sunroom that juts out onto the outdoors. An air conditioner may be installed in the inner terrace portion 21, or by opening the indoor opening 22a, air conditioning can be performed using the air conditioner in the room (living room 28).

[0041] To the east of entrance hall 23b is first floor corridor 26. That is, when one enters the house through entrance doorway 6c and moves from entrance floor 23a to entrance hall 23b, there is a passageway that includes entrance hall 23b and first floor corridor 26. On the north side of first floor corridor 26, which is such a passageway, there is a living room entrance / exit 27 formed in a wall perpendicular to indoor partition wall 22. This living room entrance / exit 27 is opened and closed by double swinging doors 27a.

[0042] Beyond the living room entrance 27 is a living room 28 that combines the functions of a kitchen, dining room, and living room. The living room 28 is located on the east side of the second work space 25. The easternmost part of living room 28 is a kitchen, and kitchen counter 28a is installed along east-side first exterior wall 4. An opening 4a that can be opened and closed is formed in east-side first exterior wall 4 in a portion located above kitchen counter 28a. To the west of the kitchen is the dining room, where dining table 28b is installed. To the west of the dining room is a living room equipped with a sofa 28c, and this living room is adjacent to the second work space section 25 via an interior partition wall 22. In addition, a refrigerator storage area 29 is provided on the east side of the living room entrance / exit 27.

[0043] To the east of the first floor corridor 26 and refrigerator area 29, there is a bathroom / dressing room 30 with a sink and washing machine area. The bathroom / dressing room 30 has an entrance / exit 30a on the first floor corridor 26 side and an entrance / exit 30b on the living room 28 side. This creates a circulation route that allows people to move around the refrigerator storage area 29 between the first floor corridor 26, living room 28, and bathroom / dressing room 30. In addition, a bathroom 31 is provided on the south side of the washroom 30. In addition, a toilet 32 ​​is provided to the west of the bathroom 31 and on the south side of the first floor corridor 26.

[0044] On the south side of the first floor corridor 26, and on the east side of the entrance 23 (west side of the toilet 32), there is a stairwell 33 equipped with a circular staircase. The wall of the stairwell 33 facing the entrance 23 is a handrail wall, and the stairwell 33 and the open space of the entrance 23 are connected to each other.

[0045] At the top of the stairs in the stairwell 33, there is a second floor corridor 34 that runs east-west. A desk 34a and chairs are provided on the southern edge of the second floor corridor 34, and can be used for teleworking or children's study.

[0046] On the east side of the second floor corridor 34 are two rooms 35, 36, which may be used as children's rooms, and a second floor toilet 37. Of the two rooms 35, 36, the northern room 35 has a desk 35a and a chair along the northern exterior wall 2.

[0047] A room 38, which may be used as a master bedroom, is provided on the north side of the second floor corridor 34. A desk 38a and a chair are also provided along the north exterior wall 2 in this room 38.

[0048] A balcony 16 is provided on the west side of room 38 and second-floor corridor 34 via west-side second exterior wall 7. This balcony 16 is an upward protrusion that juts out west from west-side first exterior wall 6, and also functions as a canopy for the outdoor opening 6a. A balustrade wall 17 is provided at the tip of the protrusion of this balcony 16, and this balustrade wall 17 is located further west than any part of west-side first exterior wall 6. The second west exterior wall 7 is formed with a first entrance 7a that connects the balcony 16 to the room 38, and a second entrance 7b that connects the balcony 16 to the second floor corridor 34.

[0049] Next, the inner terrace portion 21 will be described in more detail. The inner terrace section 21, particularly the second work space section 25, is adjacent to the living room 28, and can be easily used as an extension of the living room 28. When the indoor opening 22a is opened, the second work space section 25 and the living room 28 can be easily recognized as a single room. Furthermore, since the first work space section 24 is also located in a position that can be seen from the living room 28, it is easy to recognize the first work space section 24, the living room 28, and the second work space section 25 as one continuous room.

[0050] The inner terrace portion 21 and the living room 28 are respectively provided between the east-side first outer wall 4, the indoor partition wall 22, and the west-side first outer wall 6, which are arranged parallel to each other. Furthermore, an opening 4a is formed in the east-side first exterior wall 4, an indoor opening 22a is formed in the indoor partition wall 22, and an outdoor opening 6a is formed in the west-side first exterior wall 6, and these openings 4a, 22a, 6a are directly opposite each other. In other words, the opening 4a, the indoor opening 22a, and the outdoor opening 6a are arranged in a straight line. Therefore, by opening these openings 4a, 22a, and 6a, wind can pass through in the east-west direction. Also, wind can pass through in the east-west direction on the north side, where the temperature is relatively lower than on the south side.

[0051] If the fittings that open and close the outdoor opening 6a and the fittings that open and close the indoor opening 22a are so-called double sashes (triple sashes are also acceptable), it will be difficult for the heat of the afternoon sun to be transmitted to the living room 28. For this reason, the folding door 6b and the sliding door 22b in this embodiment are double sashes. Furthermore, because the afternoon sun passes through second work space section 25, which is a buffer space, before reaching living room 28, if folding door 6b and sliding door 22b are tightly closed, second work space section 25 will provide some degree of insulation. Therefore, in the summer, if folding door 6b and sliding door 22b are tightly closed, living room 28 can be prevented from getting too hot, and in the winter, if sliding door 22b is left open, living room 28 can be warmed by the heat of the afternoon sun.

[0052] Furthermore, the first western exterior wall 6, in which the outdoor opening 6a is formed, is located closer to the interior than the tip of the balcony 16 in the protruding direction (the position of the balustrade wall 17). As a result, sunlight is blocked by the balcony 16, making it difficult for sunlight to enter the inner terrace portion 21.

[0053] Next, the flow of people in building 1 will be explained. In this embodiment, when entering the first floor of the building 1 through the entrance 6c, there are two routes: one from the entrance 23 to the room (first floor corridor 26), and the other from passing through the first work space section 24 and the second work space section 25 to enter the room (living room 28). Furthermore, when entering the building from the outdoor opening 6a, there are two routes: one is to enter the building (living room 28) from the second work space 25, and the other is to pass through the first work space 24 and the entrance 23 before entering the building (first floor corridor 26). As described above, a circulation route is formed around refrigerator storage area 29.

[0054] If the above-mentioned traffic flow is formed on the first floor of building 1, it will be possible for residents to move around while taking into consideration infection control measures, for example. That is, if an infected resident develops symptoms at work or school and returns home to building 1, they enter the building through entrance door 6c, pass through first-floor corridor 26, go to washroom 30, and wash their hands. If necessary, they can also cleanse themselves in bathroom 31. They then pass through stairwell 33 and begin recuperation in their room on the second floor.

[0055] On the other hand, healthy (non-infected) residents should enter the house through the entrance door 6c or the outdoor opening 6a and then through their rooms 28. Hand washing, etc., should be done on the kitchen counter 28a if necessary, or in the bathroom 30 after sufficient ventilation has been achieved. The bathroom 31 should also be used after sufficient ventilation has been achieved. Furthermore, when going to the second floor, the stairwell 33 and second-floor hallway 34 should be used after sufficient ventilation has been achieved.

[0056] This type of resident movement is just one example, but there are several routes that can be used on the first floor of Building 1 to get to the washroom 30 or the second floor, which has the advantage of making it easier to avoid contact between infected residents and healthy residents.

[0057] The building 1 configured as described above is a residence, but is not limited to this and may be a building for various purposes such as a public facility, commercial facility, accommodation facility, childcare / educational facility, or nursing home. Furthermore, the inner terrace portion 21 can be used not only in multi-story buildings but also in single-story buildings.

[0058] Furthermore, the building 1 of this embodiment is constructed using a wooden framework construction method in which a plurality of columns and a plurality of cross members (beams, girders, girder beams, etc.) are assembled to construct the framework of the building, but the construction method is not limited to this. For example, the building may be constructed using a panel construction method in which components such as walls, floors, and roofs are made into panels in advance at a factory and the building is constructed by assembling these construction panels at the construction site, or it may be constructed using a wall construction method, a two-by-four construction method, etc. In this embodiment, the building 1 is made of wood, and the inner terrace section 21 is applied to such a wooden building 1, but the inner terrace section 21 can be applied to buildings of any structure, not just wooden buildings, such as steel-framed buildings and reinforced concrete buildings.

[0059] In this embodiment, the type of fittings that open and close each opening is not particularly limited. For example, although the fittings that open and close the outdoor opening 6a are described as folding doors 6b, they may be of a type other than folding doors 6b. Also, although the fittings that open and close the indoor opening 22a are described as sliding doors 22b, they may be of a type other than sliding doors 22b.

[0060] According to this embodiment, the following excellent effects are achieved. That is, the inner terrace section 21 is provided on the indoor side of the north-side exterior wall 2, south-side exterior wall 3, first east-side exterior wall 4, and first west-side exterior wall 6, and has a ceiling above it, so that it is provided as an indoor space in the building 1. For this reason, the residents can easily recognize the inner terrace section 21 as an indoor space of the building 1. On the other hand, the inner terrace section 21 has a dirt floor 12 and is separated from the living room 28 by a partition wall 22 and fittings 22b that open and close the indoor opening 22a. Furthermore, the inner terrace section 21 easily connects to the outdoor space by opening the outdoor opening 6a of the exterior wall 6, making it easy for residents to recognize it as an outdoor space. The inner terrace section 21 also has an entrance dirt floor 23a, which is closest to the outdoor space, and work spaces 24 and 25 adjacent to and continuous with the entrance dirt floor 23a, which serve as work spaces separate from the entrance 23. This helps residents recognize that they can perform work that would not normally be performed indoors only in the inner terrace section 21 (work spaces 24 and 25). In other words, the inner terrace section 21 is easily recognized as an indoor space in which the psychological barrier of performing work that should normally be performed outdoors indoors is somewhat lowered. This allows residents to easily do outdoor work or enjoy the feeling of being outdoors on the inner terrace section 21. Furthermore, if the outdoor opening 6a is closed with the fittings 6b, the inner terrace section 21 is separated from the outdoor space and has an environment similar to that of an indoor space, so outdoor work can be done comfortably even on a hot summer day. Also, if it is not a hot summer day, the outdoor opening 6a can be left open, allowing outdoor work to be done comfortably in an open environment.

[0061] In addition, since the work table 24a is installed in the first work space 24, it is possible for the residents to easily recognize the first work space 24 as a space that is different from the entrance floor 23a. Furthermore, when working in the first work space 24, various tasks can be performed using the work table 24a, making it easy to use.

[0062] Furthermore, because the opening 4a, outdoor opening 6a, and indoor opening 22a of living room 28 are aligned in a straight line, opening these openings 4a, 6a, and 22a allows air to pass from the outdoor space (west side) on the inner terrace 21 side to the outdoor space (east side) on the living room 28 side. This allows for efficient ventilation of the inner terrace 21 and living room 28, improving the comfort of the indoor environment in the inner terrace 21 and living room 28, unless it is a particularly hot summer day.

[0063] Furthermore, because the opening 4a, outdoor opening 6a, and indoor opening 22a of living room 28 are aligned in a straight line along the east-west direction, opening these openings 4a, 6a, and 22a allows air to pass along the east-west direction inside building 1. Furthermore, because inner terrace 21 and living room 28 are positioned along the north side of the perimeter of building 1, air can pass along the east-west direction inside building 1 from the north side, where the temperature is relatively lower than on the south side, further improving the comfort of the indoor environment in inner terrace 21 and living room 28.

[0064] Furthermore, the first western exterior wall 6 in which the outdoor opening 6a is formed is located closer to the interior than the tip of the balcony 16, which is the upward protrusion 16, in the protruding direction, so sunlight is blocked by the balcony 16, making it difficult for sunlight to penetrate into the inner terrace 21. This improves the comfort of the indoor environment in the inner terrace 21, especially during the daytime in summer.

[0065] Furthermore, the entrance floor 23a, the first work space 24, and the second work space 25 are arranged side by side in a first direction (frontage direction) in a plan view, and the entrance floor 23a is formed to extend in a second direction (depth direction) perpendicular to the first direction in a plan view, so that people who enter the building 1 from the entrance 23 can be guided in either the first direction or the second direction. This ensures that at least two traffic lines can be secured from the entrance 23 to the back, and each traffic line can be used separately as needed, making it easy to use. In particular, the traffic lines can be used separately when residents move around in consideration of infection control measures or when they have visitors to their rooms 28, making it easy to use.

[0066] Furthermore, the entrance floor 23a is located adjacent to the passageways 23b, 26, which run in a different direction from the work spaces 24, 25. The passageways 23b, 26 are connected to the living room 28 and allow for easy access, so people entering the building 1 from the entrance can be guided to either the work spaces 24, 25 or the passageways 23b, 26. This ensures that at least two traffic lines are secured from the entrance 23 to the living room 28, allowing each line to be used as needed, making it easy to use. In particular, the traffic lines can be used to accommodate resident movements in consideration of infection control measures or when a resident has a visitor in the living room 28, making it easy to use.

[0067] Furthermore, in recent years, there has been a demand for the realization of a carbon-neutral society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and the construction industry is also working to build buildings using wood, which has low carbon dioxide emissions. The building 1 of this embodiment is constructed using the wooden framework construction method, and can therefore contribute to the realization of a carbon-neutral society by promoting carbon neutrality, and to the achievement of the SDGs.
