<Actions and effects of the present embodiment>
Next, the operation and effects of this embodiment will be described.

In this embodiment, as shown in FIG. 1, boundary walls 14 are arranged between adjacent dwelling units 12 . A part of the outer wall 22 of the dwelling unit 12 is composed of an outer wall portion 24 . The dwelling unit 12 is provided with a floor portion 20 inside thereof, and the floor portion 20 is arranged so as to partition the inside of the dwelling unit 12 in the building height direction, and the ceiling of the living room 56 on the lower floor 18 of the dwelling unit 12 placed on the side.

By the way, in a configuration in which the floor section 20 is supported from below in the Z direction by the boundary wall section 14, when the building 10 is extended in the Z direction, a boundary wall section is newly installed on the upper side of the floor section 20. 14 would need to be installed, creating constraints on the planning of the building 10 .

Here, in the present embodiment, the floor portion 20 is supported by the outer wall portion 24 from below in the Z direction while being in contact with the boundary wall portion 14 along the boundary wall portion 14 . Therefore, in this embodiment, when the building 10 is extended in the Z direction, the boundary wall 14 can be extended in the Z direction without any restrictions. Therefore, in this embodiment, it is possible to reduce restrictions on planning of the building 10 in the Z direction.

In addition, in this embodiment, the boundary wall 14 is made of masonry or reinforced concrete, and when the building 10 is extended in the Z direction, the boundary wall 14 can be easily extended in the height direction of the building. Become. In addition, the boundary wall 14 can suppress the transmission of sound between one dwelling unit 12 and the other dwelling unit 12 partitioned by the boundary wall 14 . Therefore, in the present embodiment, it is possible to further reduce restrictions on planning of the building 10 in the Z direction, and to ensure the sound insulation performance of the building 10 .

In addition, in this embodiment, the outer wall portion 24 is configured including a steel wall frame 28, and the wall frame 28 acts on the outer wall 22 of the dwelling unit 12 compared to a configuration in which the wall frame 28 is made of wood. The rigidity of the outer wall portion 24 against the load can be ensured. Therefore, in this embodiment, the rigidity of the outer wall 22 of the building 10 against the external force acting on the building 10 can be ensured.

Further, in this embodiment, the floor section 20 of the upper floor 16 is arranged at the boundary between the upper floor 16 and the lower floor 18 of the dwelling unit 12 .

By the way, in a configuration in which the boundary wall portion 14 is separated by the floor portion 20 of the upper floor 16 at the boundary portion between the upper floor 16 and the lower floor 18 of the dwelling unit 12, the boundary wall portion 14 is constructed on the lower floor 18 side. After that, it is necessary to construct the floor section 20 of the upper floor 16 and then construct the boundary wall section 14 on the upper floor 16 side, which may make the process complicated.

Here, in this embodiment, the floor of the upper floor 16 is in contact with the boundary wall 14 along the boundary wall 14, so that the boundary wall 14 can be constructed over a plurality of floors. Therefore, in this embodiment, it is possible to prevent the process from becoming complicated when constructing the building 10 .

In addition, in this embodiment, the floor 20 of the upper floor 16 is configured including a steel floor frame 42, and compared to a configuration in which the floor frame 42 is made of wood, The rigidity of the floor 20 against the load applied can be ensured. Therefore, in the present embodiment, it is possible to suppress the generation of noise caused by the load acting on the floor section 20 of the upper floor 16 of the building 10 .

In addition, in the present embodiment, since the adjacent dwelling units 12 are separated by the boundary walls 14, even if one of the dwelling units 12 undergoes construction such as extension or demolition, the other dwelling unit 12 can be suppressed from being affected by the construction work. Therefore, in this embodiment, restrictions on planning of the building 10 can be further reduced.
