[0005] In a house with an atrium as described above, the layout of the upper floors is generally composed of a corridor facing the atrium and private rooms separated by walls and fixtures, but in such a space, it is difficult to sense the presence of family members on the floor below from the upper floor. Therefore, the invention disclosed in this application aims to create a special place from a different perspective than before, where the presence and behavior of family members on the floor below can be sensed through the atrium from the upper floor, creating a soft sense of connection with the family. The problem solved by this invention is to realize such a special place with the minimum necessary area and a rational structure that does not spoil the open atmosphere of the atrium itself. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the house of the invention disclosed in this application is a house in which the lower floor and the upper floor are connected via a void, and a staircase is installed facing the void for traveling between the lower floor and the upper floor, the lower floor is provided with a public zone where a living room and a dining room are connected, and the void is installed above the public zone, and the upper floor is provided with a private zone including a bedroom, a child's room and other private rooms, and a corridor is installed facing the void from the connecting point of the staircase and the upper floor for traveling to and from the private zone, and at least one private room in the private zone on the upper floor has a protruding floor that is triangular in plan view and protrudes above the public zone via an entrance that is not directly connected to the corridor, and is installed along the inner corner of two walls surrounding the void. The edge of the protruding floor is inclined with respect to the two walls forming the recessed corner and also with respect to the movement direction of the stairs and the corridor. , the following configuration is adopted.

[0007] In addition, the house of the invention disclosed in this application is In a house in which the lower and upper floors are connected via a void, and a staircase facing the void is installed for traveling between the lower and upper floors, a public zone consisting of a continuous living room and dining room is provided on the lower floor, and the void is installed above it, and a private zone including bedrooms, children's rooms and other private rooms is provided on the upper floor, and a corridor for traveling to and from the private zone is provided facing the void from the connecting point between the staircase and the upper floor, and at least one private room in the private zone on the upper floor has a triangular-shaped protruding floor that protrudes above the public zone through an entrance that is not directly connected to the corridor, and is installed along the corner of the two walls surrounding the void,The configuration adopted is such that a landing is provided in the middle of the staircase, and the extended floor and the landing are positioned opposite each other when viewed from above in the atrium.

[0008] Furthermore, the entire ceiling surface above the atrium is made into a sloped ceiling that slopes downward in two directions from just below the ridge, and the ceiling surface that slopes downward in at least one direction is connected to one of the wall surfaces surrounding the atrium.

[0009] It is more preferable that a window opening facing the outdoors is provided in the upper floor portion of the wall where the downwardly sloping ceiling surface is connected, and that the protruding floor is positioned with at least one edge along the wall surface in which the window opening is provided. Effect of the Invention

[0010] The house according to the invention disclosed in this application is equipped with a protruding floor that faces the atrium and protrudes above the public zone, so that by looking down from this protruding floor, one can sense the presence and behavior of the family on the floor below from an appropriate distance. This protruding floor becomes a special place that creates a soft sense of connection with the family. By making the planar shape of this protruding floor triangular and fitting it to the corner of the wall surrounding the atrium, a special place can be created without compromising the open atmosphere of the atrium itself and without straining the structural frame around the atrium.

[0012] Hereinafter, embodiments of the present invention disclosed in the present application will be described with reference to the drawings.

[0013] 1 to 4 show a two-story detached house according to one embodiment of the invention disclosed in the present application. This house 1 has a garden 11 and a garage 12 on the south side of the lot, and the main building is located toward the north side of the lot. The main building has a gabled sloped roof with the ridge facing east-west, and a large window opening is provided on the south wall 13.

[0014] On the first floor (Figure 1), an entrance hall 101 is located on the west side, and a Japanese-style room 103 is located on the north side of the entrance hall 102. In the center of the first floor, a public zone where a living room 111, dining room 112, and kitchen 113 are integrated and connected is provided facing the south wall 13. A terrace 16 that can be accessed from the public zone through a window opening is provided on the outdoor side of the south wall 13. A pantry 121 is attached to the south side of the kitchen 113, and a washroom 122 and a bathroom 123 are located to the north of the kitchen 113.

[0015] Located on the north side of the living room 111 is a staircase 3 used for travel between the living room 111 and the second floor. This staircase 3 is a return staircase with a wide landing 31 (split floor) in the middle. A corridor 131 leading to the toilet 124 is located between the landing 31 and the Japanese-style room 103. The landing 31 is surrounded by a low handrail wall 32 on both the living room 111 side and the Japanese-style room 103 side. A counter desk 33 where two or three people can sit and read and write is provided inside the handrail wall 32, and can be used as, for example, a study space for children.

[0016] An open void is formed above the staircase 3 including the landing 31, the living room 111, and part of the dining room 112. In FIG. 1, the open void is indicated by a diagonal crossing line made of dashed dotted lines.

[0017] On the second floor (Fig. 2), corridors 231, 232, 233 connect to the staircase 3 and run around the atrium. These corridors 231, 232, 233 are routes leading to a private zone consisting of the master bedroom 211 and toilet 221 located on the west side, and two children's rooms 212, 213 located on the east side. A walk-in closet 214 is attached to the master bedroom 211.

[0018] In Figure 2, the atrium (area without a floor) on the second floor is shown by dots. The north corridor 231 is surrounded by a balustrade wall 234 facing the atrium, and from here it is possible to look down on the living room 111, dining room 112, landing 31, etc. on the first floor. The east corridor 232 and the west corridor 233 are separated from the atrium by walls 51, 52 that rise up to the ceiling, and it is not possible to look down on the atrium from these corridors 232, 233. A large window opening is provided in the south wall 53 of the atrium, just like on the first floor, and a balcony 56 is provided on the outdoor side of the window opening.

[0019] The ceiling above the rectangular area (area surrounded by walls 51, 52, 53, 54) in plan view that includes the atrium and the northern corridor 231 is a boat-bottom sloping ceiling 6 that slopes downward from directly below the east-west-oriented building to the north and south like a roof, as shown in Figure 3. In Figure 2, the upper sloping ceiling 6 is represented by a diagonal crossing line made of dashed and dotted lines. In this way, by providing various types of places to stay under the large open space that extends from the lower floor to the sloping ceiling 6, a sense of security is created in the family members in each place, as if they are being embraced as one.

[0020] The main part of the invention disclosed in this application is the overhanging floor attached to the private room of the private zone and overhanging above the public zone on the lower floor. The overhanging floor 4 in the example form is a right-angled isosceles triangle in plan view, and is provided along the corner of the wall 51 that separates the master bedroom 211 from the atrium and the south wall 53. It is large enough to accommodate one chair and a small table, and a handrail is attached to the edge part 41 that is arranged diagonally to the atrium. This overhanging floor 4 is not directly connected to the corridors 231, 232, and 233, and is entered and exited through the entrance 511 provided on the wall 51 that separates the master bedroom 211 from the atrium. However, in the example form, it is also possible to enter and exit from the balcony 56 side through a window opening (floor window) provided on the south wall 53.

[0021] Figure 4 is an image of the interior looking towards the overhanging floor 4 from near the junction of the staircase 3 and the corridor 232. By separating the traffic line to the overhanging floor 4 from the everyday traffic line and hiding it behind the wall 51, the overhanging floor 4 becomes a place like a "detached house" that is psychologically distant from the everyday living space. When seen from the opposite side of the atrium or from the floor below, the overhanging floor 4 that protrudes above the atrium from the wall 51 creates a sense of exclusivity, like the box seats located to the side of the stage at an opera house.

[0022] From this overhanging floor 4, one can look down at the family members in the living room 111, dining room 112, and landing 31 of the stairs 3 on the lower floor. During the day, one can see the bright open atrium space with one's back to the south-facing window opening, which further enhances the sense of security gained by sensing the presence of the whole family.

[0023] Furthermore, because the landing 31 of the staircase 3 and the overhanging floor 4 are positioned opposite each other in a plan view of the atrium, the difference in height between the floor surface of the landing 31 and the floor surfaces of the living room 111 and dining room 112 is emphasized from the overhanging floor 4, making the entire public zone look even more three-dimensional. And you can see what the family on the landing 31 is doing and talk to them from a fairly close distance.

[0024] However, even family members may feel less relaxed if they face each other directly, as they may feel nervous and embarrassed about being watched. In this respect, the edge 41 of the protruding floor 4, where the handrail is attached, is inclined to the direction of movement of the walls 51, 52, 53 surrounding the atrium, the stairs 3, and the corridors 231, 232, 233, so that even though they share the space, their gazes do not face each other directly, but pass each other to a certain extent, reducing the sense of tension and embarrassment. In this way, by deliberately adopting a positional relationship that is not directly in front of the family, family members can feel each other's presence, but can easily immerse themselves in their own world without being disturbed by it.

[0025] In addition, by connecting the diagonal floor beams that support the triangular edge portion 41 to the structural frame of the two walls 51, 53 that form the inside corner, this protruding floor 4 can be installed with a simple structure without placing a structural burden on the structural frame or requiring any extra columns, etc.

[0026] With the above-mentioned configuration, it is possible to create a special space where people on the upper floors can sense the presence and behavior of family members on the lower floors, creating a soft sense of connection between the family members, with a minimal amount of area and a rational structure that does not spoil the open atmosphere of the atrium itself.

[0027] The technical scope of the invention disclosed in this application should not be interpreted as being limited by the exemplified embodiment, but should be interpreted conceptually based on the description of the claims. When implementing the invention disclosed in this application, the shape, structure, size, use, relative positional relationship, azimuth, etc. of the components (spatial elements) not specifically specified in the claims may be modified within a range in which substantially the same or better effects as those of the exemplified embodiment are obtained. For example, the lower floor and the upper floor are not limited to the first floor and the second floor, but may be the basement and the first floor, or the second floor and the third floor. The public zone may include a Japanese-style hall, a reception room, etc., and the private zone may include a study, a work room, a guest room, etc. The upper floor corridor facing the atrium may be in the form of a connecting corridor that passes through the atrium. In addition, modifications that do not deviate from the gist of the invention are possible as appropriate depending on the size and shape of the house. [Industrial Applicability]

[0028] The invention disclosed in this application can be widely used as a spatial configuration for a house having two or more floor levels. [Explanation of symbols]
