[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 and upper floors are connected via an atrium, and a staircase is installed facing the atrium for traveling between the lower and upper floors, a public zone consisting of a living room and dining room connected to each other is provided on the lower floor, and the atrium is provided above that, and a private zone including a bedroom, a child's room and other private rooms is provided on the upper floor, and a corridor for traveling to and from the private zone from the connecting point of the staircase to the upper floor is provided facing the atrium and going around the perimeter of the atrium, At the bending point of the traffic line connecting the corridor and the private zone The structure adopted is such that a portion of the corridor is widened to fit along at least one of the walls surrounding the atrium, and a protruding floor having a triangular shape in plan view is provided protruding above the public zone.

[0008] In addition, the house of the invention disclosed in this application is a house in which the lower and upper floors are connected via an atrium, and a staircase is installed facing the atrium for traveling between the lower and upper floors, a public zone where the living room and dining room are connected to each other is provided on the lower floor, and the atrium is provided above that, and a private zone including bedrooms, children's rooms and other private rooms is provided on the upper floor, a corridor that faces the atrium and goes around it is connected to the staircase, and part of the corridor is used as a traffic route for traveling to and from the private zone, and the end of the corridor opposite the private zone is widened to fit along at least one wall surrounding the atrium, and a protruding floor that is triangular in plan view and protrudes above the public zone is provided.

[0009] In addition, the house of the invention disclosed in this application has a configuration in which a landing is provided in the middle of the staircase, and the extended floor and the landing are positioned in opposing positions when viewed in a plan view of the atrium.

[0010] 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.

[0011] 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

[0012] 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 along the corner of the wall surrounding the atrium, a special place can be created without compromising the open atmosphere of the atrium itself.

[0014] Hereinafter, embodiments of the present invention disclosed in the present application will be described with reference to the drawings. In describing a plurality of embodiments, the same numerals and symbols will be used to designate components that have common spatial characteristics or common usage patterns.

[0015] (First embodiment) 1 to 5 show a two-story detached house according to the first 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 towards the north side of the lot. The main building has a gabled sloped roof with the ridge facing east-west, and large window openings are provided on the south wall 13 and the north wall 14.

[0016] On the first floor (Figure 1), there is a front door 101 and a spacious entrance hall 102 on the east side, and on the north side of the entrance hall 102 is a personal salon 103 where people can enjoy hobbies and invite acquaintances to socialize. A short corridor 131 extending to the west is connected to the entrance hall 102, and this corridor 131 leads to a spacious living room 111 located in the center of the first floor.

[0017] The living room 111 faces a large window opening in the south wall 13, and a terrace 16 that can be accessed from the living room 111 is provided on the outdoor side of the window opening. The living room 111 is a space that is integrated and continuous with the dining room 112 and the skip-style staircase 3 located on the north side, and this space forms the public zone on the first floor. The dining room 112 faces a large window opening in the north wall 14, and an outdoor dining room 17 is provided on the outdoor side of the window opening.

[0018] The kitchen 113 is located between the dining room 112 and the entrance hall 102, and a pantry 121 is provided on the south side of the kitchen 113. A toilet 124 and a storage room 125 are located on the south side of a hallway 131 connecting the entrance hall 102 and the living room 111. A hallway 132 extending west from the dining room 112 is provided on the north side of the staircase 3, and leads to a laundry room 126, a dressing room 122, and a bathroom 123, with a guest room 104 provided on the westernmost side.

[0019] The stairs 3 used to travel to and from the second floor have a wide landing 31 (split-level floor) in the middle, and the stairs 3 below the landing 31 and the stairs 3 above are arranged so that their ascending and descending directions cross at right angles. The landing 31 is a place like a mini stage where, for example, two or three family members can perform music or dance, and a low handrail 32 is provided on the living room 111 side. The stairs 3 including the landing 31 and approximately half the space of the living room 111 are open to the air. In FIG. 1, the open to the air above is represented by a diagonal crossing line made of dashed and dotted lines.

[0020] On the second floor (Fig. 2), corridors 231, 232, and 233 facing the atrium are provided so as to wrap around three sides of the atrium. From these corridors 231, 232, and 233, one can look down over the handrails onto the living room 111, dining room 112, landing 31, and other areas on the first floor. In Fig. 2, the atrium (area without a floor) on the second floor is shown by dots.

[0021] Corridor 231, which is connected to staircase 3 and located on the north side of the atrium, is a traffic line leading to toilet 221, closet 222, and work room 215 located on the north side. Corridor 232, which curves from north corridor 231 and runs along the east side of the atrium, is integrated with lounge 216 located on the east side. This lounge 216 is a large space where several family members or guests can gather together in a relaxed atmosphere with music playing, and serves as a second public zone on the upper floor. Large window openings are provided on south wall 53 and north wall 54 of lounge 216, and balconies 56, 57 are provided on the outdoor side of each window opening.

[0022] A corridor 233 on the south side of the atrium extends along the south wall 53 and is connected to the children's rooms 212, 213. The children's rooms 212, 213 are each divided into spaces for two people by a walk-in closet 214 in the center of the space, surrounded by a partition wall 241 that does not reach the ceiling.

[0023] A master bedroom 211 is provided on the east side of the lounge 216, via a wall 52. The entrance to the master bedroom 211 is hidden behind a partition wall 242 that does not reach the ceiling and is erected on the east side of the lounge 216. A walk-in closet 217 and an inner balcony 218 are attached to the master bedroom 211.

[0024] The wall 51 that separates the atrium from the children's rooms 212, 213, and the wall 52 that separates the lounge 216 from the master bedroom 211, both rise up to the ceiling. The ceiling above the large space sandwiched between these two walls 51, 52 is a boat-shaped sloped ceiling 6 that slopes downward from directly below the east-west ridgepole to the north and south as if it were a roof, as shown in Figure 3. In Figure 2, the sloped ceiling 6 above is represented by a diagonal crossing line made of dashed and dotted lines. In this way, by providing various types of living space below the large atrium that extends from the lower floor to the sloped ceiling 6, the whole family in each space feels a sense of security as if they are enveloped by the large sloped roof on both sides.

[0025] The main part of the invention disclosed in this application is the overhanging floor, which is provided by widening a part of the corridor and overhanging it above the public zone on the lower floor. The overhanging floor 4 in the example form is in the shape of a right-angled isosceles triangle in plan view, and is provided along the wall surface 51 at the bending point of the traffic line where the corridor 233 on the south side connects to the entrance 511 of the children's rooms 212 and 213. The overhanging floor 4 integrated with the corridor 233 is large enough to accommodate two or three chairs and a small table, and a handrail is attached to the edge part 41 arranged diagonally to the atrium. This overhanging floor 4 is a place like a "hangout" provided in the middle of the traffic line leading to the private zone, and is also a "viewing place" where the situation on the lower floor can be viewed from the upper floor through the atrium. During the day, the bright atrium space can be seen with one's back to the window opening on the south side, so the sense of security gained by feeling the presence of the whole family is further amplified.

[0026] 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, as shown in Figures 4 and 5, 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.

[0027] 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, 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.

[0028] Second embodiment 6 and 7 show a detached house according to a second embodiment of the invention disclosed in the present application. This house 1 has a two-story main house 1A with a gabled sloped roof, which is located on the north side of the site with its ridge facing east-west, and a one-story shed 1B extending southward is connected to the middle part of the main house 1A, with the roof of the shed 1B hanging over the extended surface of the roof of the main house 1A. The east side of the shed 1B is an entrance zone 18, and a roofless garden space (loggia) 19, partly enclosed by a wall, is provided on the west side of the shed 1B.

[0029] On the first floor of the main building (Figure 6), there is an entrance hall 102 and an earthen floor hall 105 on the east side, and a Japanese-style room 106 is located on the west side of the earthen floor hall 105.

[0030] A skip-style staircase 3 used for travel between the second floor and the entrance hall 102 is installed on the west side, and from the south side of the staircase 3 to the lower shed 1B is a living room 111 that is full of an open feeling to the outdoors. The living room 111 faces a large window opening on the south wall 13, and on the outdoor side of the window opening there is a semi-outdoor terrace 16 with a deep eaves that can be accessed from the living room 111.

[0031] On the west side of the staircase 3 are a dining kitchen 114 and a studio 107 that can be used for hobby projects, etc., and a pantry 121 is attached to the dining kitchen 114. The dining kitchen 114 and the entrance hall 102 are also connected via a corridor 133 provided on the north side of the staircase 3.

[0032] The stairs 3 have a wide landing 31 (split-level floor) in the middle, and the stairs 3 below the landing 31 and the stairs 3 above it are arranged on both the east and west sides of the landing 31 with the same ascending and descending direction. The landing 31 is large enough to accommodate one chair and a small table, making it a place where one can relax while keeping an eye on the family in the living room 111. Below the landing 31 is a storage room 127, which can be accessed from the corridor 133 on the north side.

[0033] The staircase 3, including the landing 31, and the living room 111 are continuous and form the public zone on the first floor, and an open atrium is formed above the staircase 3 and part of the living room 111 (part of the main house 1A). Also, above the south side of the living room 111 (part of the lower house 1B) is a sloped ceiling 61 that slopes downward to the south. In Figure 6, the open atrium is represented by a diagonal crossing line made of dashed and dotted lines.

[0034] On the second floor (Fig. 7), corridors 234, 235 facing the atrium are provided so as to wrap around both sides of the atrium. From these corridors, one can look down over the handrail onto the landing 31 of the staircase 3 and the living room 111 on the first floor. In Fig. 7, the atrium on the second floor (the area without a floor) is shown by dots.

[0035] A corridor 234 that turns around from the connection point with the staircase 3 and runs along the north side of the atrium is connected to private zones located on the north and west sides, such as the children's rooms 212 and 213, the toilet 221, the washroom 223, the bathroom 224, the master bedroom 211, and the walk-in closet 217. Therefore, this corridor 234 is a route along which the whole family frequently travels on a daily basis. The children's rooms 212 and 213 are partitioned into a space for two people with a sense of openness by erecting a partition wall 243 that does not reach the ceiling in a roughly T-shape in plan view in one space facing the corridor 234.

[0036] A corridor 235 along the east side of the atrium from the connection point with the staircase 3 extends to the south wall 53. A large window opening is provided in the south wall 53, and a balcony 56 is provided on the outdoor side of the window opening.

[0037] The walls 51 that separate the atrium, the hallway 234, the children's room 213 from the master bedroom 211 and the washroom 223 rise up to the ceiling. The ceiling above the space sandwiched between these walls 51 and the wall 52 that constitutes the east-side exterior wall of the second floor is a boat-bottom shaped sloped ceiling 6 that slopes downward from directly below the ridgepole arranged in the east-west direction to the north and south like a roof, as shown in Figure 8. In Figure 7, the sloped ceiling 6 above is represented by a diagonal crossing line made of dashed and dotted lines. In this way, by providing various types of places to live under the large atrium space from the lower floor to the sloped ceiling 6, the whole family in each place feels a sense of security as if they are enveloped by the large roofs with both slopes.

[0038] In this second embodiment, the end (dead end) of the east side corridor 235 is widened in a right-angled isosceles triangle shape in plan view along the south side wall 53, and an overhanging floor 4 is provided. The overhanging floor 4 integrated with the corridor 235 is large enough to accommodate one or two chairs and a small table, and a handrail is attached to the edge 41 arranged diagonally to the atrium. This overhanging floor 4 is a special place like a "detached house" on the opposite side of the daily traffic line leading to the private zone, and is also a "viewing place" where the situation on the lower floor can be seen from the upper floor through the atrium. During the day, the bright atrium space can be seen with one's back to the south side window opening, so the sense of security gained by feeling the presence of the whole family is further amplified.

[0039] Like the overhanging floor 4 provided in the house 1 of the first embodiment described above, this overhanging floor 4 is also positioned opposite the landing 31 of the staircase 3 in a plan view of the atrium, so that from the overhanging floor 4, the difference in height between the floor surface of the landing 31 and the floor surfaces of the living room 111 and dining kitchen 114 is emphasized, making the entire public zone on the first floor look even more three-dimensional. And you can see what's going on and talk to the family on the landing 31 from a fairly close distance.

[0040] Furthermore, because the edge portion 41 to which the handrail is attached is angled with respect to the direction of movement of the walls 51, 52, 53 surrounding the atrium, the staircase 3, and the corridors 234, 235, tension and embarrassment between family members sharing the space is alleviated, making it easier for them to be immersed in their own worlds while still feeling each other's presence, just like in the previously described embodiment.

[0041] 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.

[0042] 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]

[0043] 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]
