According to a third aspect of the present invention, in a unit building formed by joining a plurality of building units, the building unit according to the first or second aspect is used as a part of those building units. .

According to the present invention described in claims 1 and 3, the following operational effects are obtained. At least a part of the upper edge portion of the wall structure of the living room of the building unit with a balcony is a sloping upper edge portion capable of supporting a sloping roof. As a result, the living room of the building unit with a balcony has a chamfered shape or a trapezoidal shape, so that it is possible to improve the appearance design of the unit building and improve the adaptability to the diagonal line restriction in the construction method.

According to the present invention described in claims 2 and 3, the following operational effects are obtained. The chamfered shape has a part of the upper edge of the wall structure of the living room of the building unit with a balcony as the inclined upper edge and the rest as the horizontal upper edge. Here, when the maximum height of the wall structure that constitutes the building unit is constant, the under-roof space volume of the chamfered living room becomes larger than the under-roof space volume of the trapezoidal room. Therefore, by constructing a chamfered living room that takes the horizontal upper edge of the living room as large as possible within the range corresponding to the diagonal line restriction in the Building Law, the space under the roof of the living room is maximized as much as possible. , Habitability can be improved.
