  In the prior art described in Patent Document 1, since the living room is arranged on the south side inside the building, when the building is built on a narrow site in the urban area, a sufficient separation distance from the neighboring house on the south side is provided. It was difficult to secure privacy because it could not be secured. An object of the present invention is to provide a building in which the privacy of a living room can be easily secured.

The building of the present invention is formed on a lower floor, an upper floor arranged above the lower floor, and an intermediate floor located between the lower floor and the upper floor in the vertical direction. A first living room, a blow-out portion that is adjacent to the first living room in plan view and communicates with the first living room, and an outer floor that is adjacent to the blow-out portion in plan view and has a height substantially equal to the upper floor, and a first outer peripheral wall partitioning the and outer floor atrium portion having a first window, outside the floor in a first direction in a plan view, the blow unit is arranged in order of the intermediate floor, the intermediate floor The first staircase that connects the upper floor and the second staircase that is formed on the upper floor and that is adjacent to the stairwell and the external floor in the second direction that intersects the first direction in plan view A second outer peripheral wall having two windows and partitioning the second living room and the outer floor is further provided, and the first outer peripheral wall and the second outer wall in plan view. To form inside corner and perpendicular to the wall, the first stairs is characterized in that it is arranged along a first direction and adjacent to the second room in a blow unit.

  In this building, in addition to the outer floor, the blow-through portion is interposed between the first living room and the adjacent land, and the first living room can be arranged away from the adjacent land. Furthermore, in this building, the floor of the first living room is set lower than the floors of the upper floors, so the floor of the first living room is lower than the external floor located on the adjacent land side, and the first living room It is possible to make it difficult to see the floor surface of, and it becomes easy to secure the privacy of the first living room. Further, since the first window is provided on the first outer peripheral wall that separates the blow-out portion and the external floor, the first window is arranged at a relatively high position when viewed from the first living room. It is possible to take in sunlight through the first window diagonally above one living room. Therefore, the lighting performance can be improved while ensuring the privacy of the first living room. Further, since the first outer peripheral wall having the first window is arranged adjacent to the blow-through portion, the sunlight taken in through the first window reaches the lower floor through the blow-through portion. This improves the lighting performance even in the indoor space on the lower floor. The height substantially equal to that of the upper floor includes a height equal to that of the upper floor, and includes a height slightly lower than that of the upper floor (lower than the upper floor) due to reasons such as rain. For example, it may be about 0 to 100 mm lower than the upper floor.

Here, the first staircase connecting the middle floor and the upper floor, and the first staircase formed on the upper floor and adjacent to the blow-through portion and the outer floor in the second direction intersecting the first direction in a plan view. It further comprises a second living room and a second outer peripheral wall having a second window also serving as a doorway and partitioning the second living room and the external floor, and the first outer peripheral wall and the second outer peripheral wall are orthogonal to each other in a corner when viewed in plan view. And the first staircase is arranged in the blow-out portion adjacent to the second living room along the first direction . In the building having this structure, the first staircase connecting the middle floor and the upper floor can be used to pass through the stairwell in the first direction to reach the second living room from the first living room. Since the second living room can go out to the outer floor through the second window, the first living room is not adjacent to the outer floor, but the outer floor can be easily accessed only by going up by half a floor.

Further, the first staircase may be linear in a plan view and may be arranged so as not to project from the virtual straight line extending from the second outer peripheral wall in the first direction toward the blow-out portion. In addition, the first staircase may be provided with a landing area having a rectangular shape in a plan view at an upper portion, and two sides of the landing area along the first direction and the side surface along the second direction may be in contact with the upper floor.

In addition, the building of the present invention further includes a second staircase that connects the lower floor and the intermediate floor, and the second staircase is arranged linearly in both a plan view and a side view, and the first staircase in the second direction. It may be arranged adjacent to the stairs.

  According to the present invention, it is possible to provide a building in which privacy of a living room can be easily secured.
