[Figure 5] 2 is a diagram showing details of the configuration of a raised ceiling portion of the building shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of a building according to the present invention will be described with reference to the drawings. The same reference numerals are used to designate common components in the drawings.

[0020] 1 and 2 are side views of a building 100 as one embodiment of a building according to the present invention. The side of the building 100 shown in FIG. 2 shows the side of the building 100 located on the right side in a side view of the building 100 shown in FIG. 1. FIG. 3 is a plan view of the second floor of the building 100. FIG. 4 is a plan view of the rooftop floor of the building 100. FIG. 5 is a diagram showing the details of the configuration of the folded ceiling portion 21b of the building 100.

[0021] First, an overview of the building 100 of this embodiment will be described. The building 100 of this embodiment is a two-story detached house with a steel frame. Although the building 100 of this embodiment is a detached house, it may also be, for example, an apartment building with multiple dwelling units. Furthermore, although the building 100 of this embodiment is two-story, it may also be configured with three or more floors.

[0022] The building 100 of this embodiment comprises a reinforced concrete foundation and a superstructure supported by the foundation, which has a framework made up of framework members such as columns and beams. The superstructure of this embodiment has a steel framework, but may also have a wooden framework, for example, and its structure is not particularly limited. The framework members that make up the framework of the building 100 of this embodiment are standardized in advance and are manufactured in a factory before being transported to the construction site and assembled.

[0023] More specifically, the superstructure of the building 100 of this embodiment includes the above-mentioned framework, an exterior wall 101, and a floor 102.

[0024] The exterior wall 101 is a wall that separates the indoor space from the outdoor space of the building 100. The exterior wall 101 of the building 100 in this embodiment has an exterior finishing layer formed by connecting panel-shaped exterior materials made of lightweight aerated concrete (ALC). However, the exterior materials may also be metal or ceramic siding, extruded cement boards, wood panels, etc.

[0025] The exterior wall 101 also has a heat insulating layer formed by connecting panels of foamed resin heat insulating material such as phenol foam along the inner surface of the exterior finishing layer. However, the heat insulating material may also be made of a fiber-based material such as rock wool.

[0026] Furthermore, the exterior wall 101 has an interior finishing layer made of interior materials that are made up of a gypsum board and a finishing material such as wall paper attached to the surface of the gypsum board. However, the configuration of the interior materials is not limited to the configuration of this embodiment.

[0027] As shown in FIG. 5, the floor 102 of the building 100 of this embodiment includes floor slab materials 201a and 201b. As will be described in detail later, the floor slab material 201a of this embodiment is installed between the first beams 104a of the framework and supported by the first beams 104a. Furthermore, as will be described in detail later, the floor slab material 201b of this embodiment is installed between the second beams 104b of the framework and supported by the second beams 104b. The floor slab materials 201a and 201b may be, for example, ALC panels, but other materials such as folded plates, extruded cement boards, and wood-based panels may also be used. In addition to the floor slab materials 201a and 201b, the floor 102 may also include, for example, ceiling finishing materials 202a and 202b that form the ceiling surface of the lower floor and are attached directly or indirectly to the floor slab materials 201a and 201b. The floor 102 may also include floor finishing materials 203a and 203b that constitute the floor surface of the upper floor and are laminated on the floor slab materials 201a and 201b.

[0028] The roof of the building 100 in this embodiment is a flat roof, and its configuration is similar to that of the floor 102 described above. The floor finishing materials 203a and 203b of the flat roof are waterproof sheets made of, for example, polyvinyl chloride resin. However, the roof of the building 100 is not limited to the flat roof of this embodiment, and may be a sloped roof using roof exterior materials such as slate.

[0029] Next, the second floor of the building 100 of this embodiment will be described in detail with reference to FIGS.

[0030] The second floor of building 100 is provided with a corridor 11, a stairwell 12, a washroom 13, a toilet 14, a study 15 as a living room, a private room 16 as a living room, a living-dining-kitchen 17 as a living room (hereinafter simply referred to as "LDK 17"), and a veranda 18 as a private outdoor space. Note that "living room" means "a room used continuously for residence, office work, work, meetings, recreation, or other similar purposes" as defined in Article 2, Paragraph 4 of the Building Standards Act. Furthermore, "private outdoor space" refers to a veranda, terrace, balcony, etc. that is primarily used by the residents of building 100, for example, if building 100 is a detached house.

[0031] The ceiling surface of the living / dining / kitchen kitchen 17 is a raised ceiling. Specifically, as shown in Fig. 5, the ceiling surface of the living / dining / kitchen kitchen 17 includes a standard ceiling portion 21a and a raised ceiling portion 21b that is located higher than the standard ceiling portion 21a.

[0032] In the living-dining-kitchen-kitchen (LDK) 17 of this embodiment, a raised ceiling portion 21b is located above the center of the living space 17a. Also, in the living-dining-kitchen-kitchen (LDK) 17 of this embodiment, standard ceiling portions 21a are located above the outer edges of the living space 17a, above the dining space 17b, and above the kitchen space 17c equipped with a kitchen set 17c1. Furniture such as a sofa and a television are located in the living space 17a of this embodiment. A dining table is located in the dining space 17b of this embodiment.

[0033] In the LDK 17 of this embodiment, the living space 17a, dining space 17b, and kitchen space 17c are arranged in a substantially L-shape in a plan view (see FIG. 3). More specifically, in the LDK 17 of this embodiment, the living space 17a and dining space 17b are arranged side by side in the left-right direction in the plan view of FIG. 3. In the LDK 17 of this embodiment, the dining space 17b and kitchen space 17c are arranged side by side in the up-down direction in the plan view of FIG. 3. The columns 105 of the framework of the building 100 of this embodiment are arranged at the intersections of the grid lines that are arranged in a lattice pattern in the left-right and up-down directions in the plan view of FIG. 3. In other words, in this embodiment, the left-right and up-down directions in the plan view of FIG. 3 are parallel to the grid lines. Therefore, for the sake of convenience, the horizontal direction in which the living space 17a and the dining space 17b are lined up in the plan view of Figure 3 will be referred to as the "first street core direction A," and the vertical direction in which the dining space 17b and the kitchen space 17c are lined up in the plan view of Figure 3 will be referred to as the "second street core direction B."

[0034] The balcony 18 is disposed adjacent to the living / dining / kitchen area 17 across the exterior wall 101. More specifically, the balcony 18 of this embodiment extends in a substantially L-shape in plan view (see FIG. 3 ) and is disposed facing two sides of the living / dining / kitchen area 17.

[0035] A first opening 101a1 is formed in a portion of the exterior wall 101 that separates the living / dining / kitchen area 17 from the balcony 18, on the side of the building 100 shown in FIG. 2 (hereinafter referred to as the "first exterior wall 101a"). In this embodiment, a folding door serving as a fitting 106 that can be folded to open and close is disposed in the first opening 101a1. The fitting 106 preferably includes a viewing element that allows the outside to be viewed from the living / dining / kitchen area 17. Specifically, the fitting 106 may be, for example, a shoji screen that includes a transparent glass plate as the viewing element and a frame attached to the outer edge of the glass plate. The folding door serving as the fitting 106 in this embodiment may be configured to be opened and closed by folding the above-mentioned shoji screen, for example. By employing such a folding door as the fitting 106, substantially the entire width of the first opening 101a1 can be opened.

[0036] Furthermore, a second opening 101b1 is formed in a portion of the exterior wall 101 that separates the living / dining / kitchen area 17 from the balcony 18, on the side of the building 100 shown in FIG. 1 (hereinafter referred to as the "second exterior wall 101b"). In this embodiment, a sliding door serving as an openable / closable fixture 107 is disposed in the second opening 101b1. The fixture 107 preferably includes a viewing member that allows the outside to be seen from the living / dining / kitchen area 17. The sliding door serving as the fixture 107 in this embodiment may be configured, for example, as a shoji screen having a glass plate and a frame portion attached to the outer edge of the glass plate.

[0037] However, the fitting 106 placed in the first opening 101a1 and the fitting 107 placed in the second opening 101b1 are not limited to the configuration of this embodiment. The fitting 106 placed in the first opening 101a1 may have a different configuration, such as a sliding door. The fitting 107 placed in the second opening 101b1 may have a different configuration, such as a folding door. Furthermore, a fixed-type viewing element that cannot be opened or closed may be placed in part or all of each of the first opening 101a1 and the second opening 101b1.

[0038] Furthermore, first opening 101a1 and second opening 101b1 are provided at positions visible from a position covered by raised ceiling portion 21b in living / dining / kitchen 17 (which in this embodiment is the center of living space 17a). With this arrangement, from a position directly below raised ceiling portion 21b, the balcony 18, which is the private outdoor space, can be seen through first opening 101a1 and second opening 101b1. In other words, a person using living / dining / kitchen 17 as a living room can easily sense the spaciousness to the outside through first opening 101a1 and second opening 101b1 while feeling the spaciousness in the vertical direction due to raised ceiling portion 21b from a position directly below raised ceiling portion 21b.

[0039] In addition, in a front view of the first opening 101a1 (see FIG. 2), the width W1 of the first opening 101a1 is preferably at least half the width W2 of the raised ceiling portion 21b, more preferably at least two-thirds the width W2 of the raised ceiling portion 21b, and particularly preferably approximately equal to the width W2 of the raised ceiling portion 21b, as in this embodiment. By configuring the first opening 101a1 to be wide in this way, the unity between the living room / dining / kitchen area 17 as a living room and the veranda 18 as a private outdoor space can be further enhanced through the first opening 101a1. Furthermore, by making the width W1 of the first opening 101a1 not wider than the width W2 of the raised ceiling portion 21b, the privacy of the living room / dining / kitchen area 17 can be ensured.

[0040] Furthermore, in a front view of the first opening 101a1 (see FIG. 2), it is preferable that the arrangement area AR1 in the width direction of the first opening 101a1 (in this embodiment, the same direction as the second street center direction B) and the arrangement area AR2 in the width direction of the folded-up ceiling portion 21b (in this embodiment, the same direction as the second street center direction B) at least partially overlap. This arrangement makes it easier to see the outside through the first opening 101a1 from a position directly below the folded-up ceiling portion 21b (in this embodiment, the center of the living space 17a). In other words, a person using the living / dining / kitchen area 17 as a living room can easily sense the spaciousness of the space in the vertical direction created by the folded-up ceiling portion 21b from a position directly below the folded-up ceiling portion 21b, and can also more easily sense the spaciousness of the space to the outside through the first opening 101a1.

[0041] In particular, in this embodiment, when viewed from the front of the first opening 101a1 (see FIG. 2), the arrangement area AR1 of the first opening 101a1 and the arrangement area AR2 of the folded-up ceiling portion 21b overlap substantially entirely. In other words, in this embodiment, when viewed from the front of the first opening 101a1 (see FIG. 2), the arrangement area AR2 of the folded-up ceiling portion 21b overlaps substantially entirely with the arrangement area AR1 of the first opening 101a1. This arrangement makes it easier to see outside through the first opening 101a1 from a position directly below the folded-up ceiling portion 21b (in this embodiment, the center of the living space 17a). In other words, a person using the living / dining / kitchen area 17 as a living room can feel the vertical expansion of the folded-up ceiling portion 21b from a position directly below the folded-up ceiling portion 21b, and can also more easily feel the expansion to the outside through the first opening 101a1. In this embodiment, as shown in Figure 3, the placement area AR1 of the first opening 101a1 and the placement area AR2 of the raised ceiling portion 21b both extend over approximately the entire area between the two pillars 105 of the frame structure of the building 100.

[0042] Furthermore, in a front view of second opening 101b1 (see FIG. 1), width W3 of second opening 101b1 is preferably at least half the width W4 of coved ceiling portion 21b, more preferably at least two-thirds the width W4 of coved ceiling portion 21b, even more preferably approximately equal to width W4 of coved ceiling portion 21b, and particularly preferably wider than width W4 of coved ceiling portion 21b, as in this embodiment. By configuring second opening 101b1 to be wide in this way, the unity between living / dining / kitchen area 17 as a living room and veranda 18 as a private outdoor space can be further enhanced through second opening 101b1.

[0043] Furthermore, in a front view of the second opening 101b1 (see FIG. 1), it is preferable that the arrangement area AR3 in the width direction of the second opening 101b1 (in this embodiment, the same direction as the first centerline direction A) and the arrangement area AR4 in the width direction of the folded-up ceiling portion 21b (in this embodiment, the same direction as the first centerline direction A) at least partially overlap. This arrangement makes it easier to see the outside through the second opening 101b1 from a position directly below the folded-up ceiling portion 21b (in this embodiment, the center of the living space 17a). In other words, a person using the living-dining-kitchen-kitchen 17 as a living room can feel the vertical expansion of the folded-up ceiling portion 21b from a position directly below the folded-up ceiling portion 21b, and can also more easily feel the expansion to the outside through the second opening 101b1.

[0044] In particular, in this embodiment, when viewed from the front of the second opening 101b1 (see FIG. 1), substantially the entire arrangement area AR4 of the folded-up ceiling portion 21b overlaps with the arrangement area AR3 of the second opening 101b1. This arrangement makes it easier to see the outside through the second opening 101b1 from a position directly below the folded-up ceiling portion 21b (in this embodiment, the center of the living space 17a). In other words, a person using the living / dining / kitchen area 17 as a living room can feel the vertical expansion of the folded-up ceiling portion 21b from a position directly below the folded-up ceiling portion 21b, and can also more easily feel the expansion to the outside through the second opening 101b1.

[0045] Furthermore, the first opening 101a1 and the second opening 101b1 preferably have a height equal to or greater than two-thirds of the inner surface of the exterior wall 101 facing the living room, and more preferably have a height substantially equal to that of the inner surface. In this embodiment, the inner surface of the exterior wall 101 facing the living room refers to the inner surface of the exterior wall 101 facing the living-dining / kitchen-kitchen 17, and the height of the inner surface refers to the ceiling height L1 (see FIGS. 1, 2, and 5) at the position of the reference ceiling portion 21a of the living-dining / kitchen-kitchen 17. That is, the first opening 101a1 and the second opening 101b1 in this embodiment preferably have a height equal to or greater than two-thirds of the ceiling height L1 at the position of the reference ceiling portion 21a of the living-dining / kitchen-kitchen 17, and more preferably have a height substantially equal to the ceiling height L1 at the position of the reference ceiling portion 21a of the living-dining / kitchen-kitchen 17. In this way, by increasing the height of the first opening 101a1 and the second opening 101b1, the unity between the living room / dining / kitchen area 17 as a living room and the balcony 18 as a private outdoor space can be further enhanced through the first opening 101a1 and the second opening 101b1.

[0046] In this embodiment, both the first opening 101a1 and the second opening 101b1 have a height substantially equal to the ceiling height L1 at the position of the reference ceiling portion 21a of the living / dining / kitchen area 17, but this is not limiting. For example, only the first opening 101a1 may have a height equal to or greater than 2 / 3 of the ceiling height L1.

[0047] As shown in FIG. 3 , the veranda 18, serving as a private outdoor space, is provided with a privacy wall 31 having a height L2 (see FIGS. 1 and 2 ) of 1,700 mm or more relative to the floor of the living / dining / kitchen kitchen 17, located in a position visible through the first opening 101a1 from a position covered by the coved ceiling 21b in the living / dining / kitchen kitchen 17 (living space 17a in this embodiment). By providing such a privacy wall 31, the space between the first exterior wall 101a and the privacy wall 31 on the veranda 18 is difficult to see from the outside, ensuring privacy. Furthermore, providing the privacy wall 31 limits visibility into the living / dining / kitchen kitchen 17 from the outside through the first opening 101a1. In other words, providing the privacy wall 31 on the veranda 18 ensures privacy for the living / dining / kitchen kitchen 17, serving as a living room with the coved ceiling 21b, and for the veranda 18, serving as a private outdoor space.

[0048] In this way, in building 100, living / dining / kitchen room 17 as a living room with raised ceiling portion 21b and veranda 18 as a dedicated outdoor space are integrated through first opening 101a1, while privacy is ensured in living / dining / kitchen room 17 and veranda 18 by providing balcony 18 with a screen wall 31. In other words, building 100 can achieve both integration of living room (living / dining / kitchen room 17 in this embodiment) with raised ceiling portion 21b and dedicated outdoor space (veranda 18 in this embodiment), and ensuring privacy in living room (living / dining / kitchen room 17 in this embodiment) with raised ceiling portion 21b and dedicated outdoor space (veranda 18 in this embodiment).

[0049] The height L2 of the privacy wall 31 is preferably 1800 mm or more, and more preferably 1900 mm or more, which can further enhance privacy in the living room, dining room, and kitchen 17 as a living room with the raised ceiling portion 21b and the veranda 18 as a private outdoor space.

[0050] On the other hand, the height L2 of the privacy wall 31 is preferably 2300 mm or less, more preferably 2200 mm or less, and particularly preferably 2100 mm or less, which can reduce the oppressive feeling caused by the privacy wall 31 on the balcony 18 as a private outdoor space.

[0051] As in the present embodiment, the privacy wall 31 may have the same configuration as the exterior wall 101. Furthermore, although the privacy wall 31 of the present embodiment does not have an opening and does not have a portion through which view can be seen in the thickness direction, an opening may be formed in the privacy wall 31. However, it is preferable that the opening in the privacy wall 31 be located at a position that can prevent a decrease in privacy through the opening in the privacy wall 31, for example, at a height of 1,400 mm or more from the floor of the living, dining, and kitchen area 17. Furthermore, privacy may be ensured by reducing the area occupied by the opening in the privacy wall 31, for example, by occupying an area of ​​23% or less of the entire in-plane area of ​​the privacy wall 31.

[0052] The privacy wall 31 of this embodiment includes a wall main body portion 31a extending in the extension direction of the first exterior wall 101a (the same direction as the second street-center direction B in this embodiment) in a plan view (see FIG. 3), a first extended wall portion 31b extending from one end of the wall main body portion 31a toward the first exterior wall 101a in a plan view (see FIG. 3), and a second extended wall portion 31c extending from the other end of the wall main body portion 31a toward the first exterior wall 101a in a plan view (see FIG. 3). The first extended wall portion 31b of this embodiment is located opposite the first opening 101a1 in a plan view (see FIG. 3). The first extended wall portion 31b extends from one end of the wall main body portion 31a toward the first opening 101a1 and terminates at a position opposite the first opening 101a1. In contrast, the second extended wall portion 31c in this embodiment is provided at a position that does not face the first opening 101a1 in a plan view (see FIG. 3). The second extended wall portion 31c extends from the other end of the wall main body portion 31a toward the first outer wall 101a and is continuous with the first outer wall 101a. In other words, the wall main body portion 31a and the second extended wall portion 31c extend along the outer edge of the balcony 18.

[0053] Furthermore, the veranda 18 serving as a private outdoor space in this embodiment is provided with a handrail 32 that is located in a position that is visible through the first opening 101a1 from a position covered by the raised ceiling 21b in the living / dining / kitchen kitchen 17 serving as a living room (living space 17a in this embodiment) and that is lower than the privacy wall 31, but does not overlap with the privacy wall 31. The height L3 of the handrail 32 is set to, for example, 1000 mm to 1500 mm from the floor surface of the living / dining / kitchen kitchen 17 serving as a living room. By providing such a handrail 32 in addition to the privacy wall 31, the outside can be seen from inside the living / dining / kitchen kitchen 17 through the first opening 101a1 over the handrail 32. That is, by using the privacy wall 31 to control visibility from the outside and ensuring the privacy of the LDK 17 and the veranda 18, while providing the handrail portion 32 in a position where the privacy wall 31 is not provided, it becomes possible to see the outside from the LDK 17 and the veranda 18 through the first opening 101a1 and over the handrail portion 32, thereby enhancing the sense of openness of the LDK 17 and the veranda 18. That is, by providing the privacy wall 31 and the handrail portion 32, it is possible to ensure the privacy of the LDK 17 and the veranda 18 and to improve the sense of openness of the LDK 17 and the veranda 18 at the same time.

[0054] More specifically, the handrail portion 32 of this embodiment includes a first handrail portion 32a extending in the extension direction of the first exterior wall 101a (the same direction as the second street center direction B in this embodiment) in a plan view (see FIG. 3), and a second handrail portion 32b extending in the extension direction of the second exterior wall 101b (the same direction as the first street center direction A in this embodiment) in a plan view (see FIG. 3). The first handrail portion 32a and the second handrail portion 32b of this embodiment are connected in an L-shape along the outer edge of the balcony 18 in a plan view (see FIG. 3).

[0055] In this embodiment, the privacy wall 31 and the first handrail portion 32a are erected opposite the first exterior wall 101a at different positions in the extension direction of the first exterior wall 101a (the same direction as the second street center direction B in this embodiment) in a plan view (see FIG. 3). More specifically, the first handrail portion 32a in this embodiment is arranged adjacent to the privacy wall 31 along the extension direction of the first exterior wall 101a in a plan view (see FIG. 3). In particular, the first handrail portion 32a in this embodiment is arranged so as to be linearly continuous with the wall main body portion 31a of the privacy wall 31 along the extension direction of the first exterior wall 101a.

[0056] 2 and 3, a portion of the privacy wall 31 and a portion of the first handrail portion 32a in this embodiment are disposed opposite the first opening 101a1 of the first outer wall 101a. That is, in the side view shown in FIG. 2, a portion of the privacy wall 31 overlaps the first opening 101a1. Also, in the side view shown in FIG. 2, a portion of the first handrail portion 32a overlaps the first opening 101a1.

[0057] The configuration of the handrail section 32 is not particularly limited. For example, the handrail section 32 may be a waist wall having the same configuration as the exterior wall 101. The handrail section 32 may also be configured to include handrail bars, balusters, and posts. Furthermore, the handrail section 32 may be configured to include a transparent panel material such as glass or resin, as in this embodiment.

[0058] As shown in FIG. 1 and other figures, the building 100 of this embodiment includes a eaves portion 41 that protrudes from a position above the first opening 101a1 and the second opening 101b1 of the exterior wall 101 toward the balcony 18 in a plan view (see FIG. 3). More specifically, the eaves portion 41 of this embodiment includes a first eaves portion 41a that covers the balcony 18 on the first opening 101a1 side and a second eaves portion 41b that covers the balcony 18 on the second opening 101b1 side. The first eaves portion 41a and the second eaves portion 41b of this embodiment are formed by portions of the flat roof floor 102 that protrude beyond the exterior wall 101, but the configuration of the first eaves portion 41a and the second eaves portion 41b is not limited to this configuration. The first eaves portion 41a and the second eaves portion 41b may be formed, for example, by eaves members that protrude from the exterior wall 101.

[0059] By providing the eave portion 41, the horizontal continuity and unity between the living room, dining room, and kitchen 17 as a living room and the veranda 18 as a private outdoor space can be further emphasized.

[0060] The first overhanging portion 41a in this embodiment protrudes to a position where it covers the upper part of the privacy wall 31. More specifically, the first overhanging portion 41a in this embodiment protrudes to a position where it covers the upper part of a part of the wall main body portion 31a of the privacy wall 31 and the entire first extension wall portion 31b. However, the first overhanging portion 41a does not have to protrude to a position where it covers the privacy wall 31.

[0061] Furthermore, in this embodiment, the space between the first exterior wall 101a and the privacy wall 31 of the balcony 18 serving as a private outdoor space in a plan view (see FIG. 3) includes a first space 18a covered by the first eaves portion 41a and a second space 18b not covered by the first eaves portion 41a. This configuration creates a sense of openness varying in the space between the first exterior wall 101a and the privacy wall 31. In this embodiment, the portion of the space between the first exterior wall 101a and the privacy wall 31 facing the first opening 101a1 of the first exterior wall 101a is defined as the first space 18a, and the portion of the space not facing the first opening 101a1 of the first exterior wall 101a is defined as the second space 18b.

[0062] In this embodiment, the second eaves portion 41b covers the entire space of the balcony 18 facing the second exterior wall 101b, but is not limited to this configuration. The second eaves portion 41b may cover only a portion of the space of the balcony 18 facing the second exterior wall 101b.

[0063] Next, the ceiling surface of the living / dining / kitchen area 17 of this embodiment will be described in detail.

[0064] As described above, the ceiling surface of the living-dining-kitchen-kitchen (LDK) 17 serving as a living room in this embodiment includes the standard ceiling portion 21a and the raised ceiling portion 21b. The standard ceiling portion 21a is lower than the raised ceiling portion 21b. As shown in FIG. 3, the standard ceiling portion 21a in this embodiment is located between the raised ceiling portion 21b and the first and second openings 101a1 and 101b1 in a plan view. With this configuration, a portion of the living-dining-kitchen-kitchen (LDK) 17 covered by the raised ceiling portion 21b (living space 17a in this embodiment) is sandwiched between the balcony 18 serving as a private outdoor space and a portion of the living-dining-kitchen-kitchen (LDK) 17 covered by the raised ceiling portion 21b (living space 17a in this embodiment), which creates a sense of openness, thereby creating a sense of openness that varies in intensity.

[0065] 5, the raised ceiling portion 21b in this embodiment is formed by vertically shifting the floor 102 of the upper floor (a flat-roofed floor in this embodiment). Specifically, the ceiling surface of the living / dining / kitchen area 17 in this embodiment is formed by the underside of the floor 102 of the upper floor. The floor 102 of the upper floor comprises a first floor portion 102a, the underside of which is the reference ceiling portion 21a, and a second floor portion 102b, which is positioned above the first floor portion 102a and has the raised ceiling portion 21b as its underside. The first floor portion 102a and the second floor portion 102b have approximately the same thickness.

[0066] The first floor section 102a is supported by a first beam 104a as a first skeleton of the building 100. The second floor section 102b is supported by a second beam 104b as a second skeleton arranged above the first beam 104a of the building 100 so as to overlap it in a plan view.

[0067] More specifically, the first floor section 102a of this embodiment includes a floor slab material 201a erected and supported between the first beams 104a, a ceiling finishing material 202a constituting the reference ceiling section 21a, and a floor finishing material 203a. The second floor section 102b of this embodiment includes a floor slab material 201b erected and supported between the second beams 104b, and a ceiling finishing material 202b and a floor finishing material 203b constituting the raised ceiling section 21b.

[0068] In this embodiment, the first beam 104a and the second beam 104b are formed of H-shaped steel with a pair of upper and lower flanges connected at their central portions by a web, and are bolted together via connecting fittings 110. The floor slab material 201a of the first floor portion 102a and the floor slab material 201b of the second floor portion 102b are supported by the first beam 104a and the second beam 104b, respectively, directly or indirectly via other members. Although not shown, the interior spaces of the first floor portion 102a and the second floor portion 102b can be filled with airtight plastic insulation material such as phenol foam, fiber insulation material such as glass wool, or sound-insulating (sound-absorbing) material such as rock wool, thereby improving thermal insulation and sound insulation. With this configuration, the second floor section 102b can be reliably supported by the second beams 104b on the upper floor side of the first floor section 102a with a simple configuration, without changing the height of the first beams 104a that make up the structural grid of the building 100. This makes it possible to partially shift the height of the floor 102 upward and partially increase the ceiling height.

[0069] In this embodiment, the first beam 104a and the second beam 104b are used as examples of the first and second frames of the building 100, but frames other than the beams of the building 100 may also be used, and the configuration is not limited to that of this embodiment.

[0070] As described above, by configuring the ceiling surface of the living room / dining / kitchen kitchen 17 as described above, there are fewer restrictions on the installation area and height of the raised ceiling portion 21b compared to a configuration in which a raised ceiling portion is provided inside the pocket space. Therefore, by using the above configuration, it is possible to realize a raised ceiling portion 21b with a high ceiling height without narrowing the pocket space.

[0071] Furthermore, when the ceiling surface of the living room / dining / kitchen kitchen 17 is configured as described above and the first and second eaves 41a and 41b are formed by portions of the flat roof floor 102 that protrude above the exterior wall 101, as in this embodiment, it is preferable that the standard ceiling 21a be positioned between the raised ceiling 21b and the first and second openings 101a1 and 101b1 in a plan view, as shown in Fig. 3. Even if the raised ceiling 21b is provided adjacent to the first and second openings 101a1 and 101b1, the raised ceiling 21b must terminate (lower to the position of the standard ceiling 21a) at the height of the first beam 104a above the first and second openings 101a1 and 101b1, and the first and second eaves 41a and 41b cannot be provided so as to continue horizontally from the ceiling height of the raised ceiling 21b. Therefore, as in this embodiment, by providing a standard ceiling portion 21a at a position adjacent to the first opening 101a1 and the second opening 101b1, and providing a first eave portion 41a and a second eave portion 41b so as to be horizontally continuous from the ceiling height of this standard ceiling portion 21a, the horizontal continuity and unity between the living / dining / kitchen area 17 and the balcony 18 can be further emphasized.
