Thus, the building unit 1 in the present embodiment has the recess 16 in which the outdoor unit is installed. Thereby, when the building unit 1 is installed on the site for housing construction, an outdoor unit can be installed in the recess 16. Therefore, the free space in the site can be used effectively. In particular, even if the outer wall of the house is close to the land boundary with the neighbor, by providing the recess 16 on the side of the building unit 1 next to the house (that is, the land boundary between the own site and the adjacent site), the outer wall of the house Since it is not necessary to install an outdoor unit in a narrow space in the site between the land and the land boundary (neighboring site), it can be avoided that the open space between the neighboring house is narrowed by installing the outdoor unit outdoors . In addition, since an empty space (passage) between the outer wall of the home and the land boundary is not narrowed, maintenance of the outdoor unit can be easily performed.

Further, in the present embodiment, an upper portion 18a exists as an upper surface portion on the concave portion 16, and the upper portion 18a functions as an eaves. Thus, even if the outdoor unit is not provided with a hood or the like, it is possible to prevent the outdoor unit from being exposed to wind and rain or direct sunlight by installing the outdoor unit in the recess 16, so that the outdoor unit may break down. It is possible to suppress the life from being shortened and the functional performance from being lowered.

Also, the outdoor unit can be hidden in the recess 16 by installing the outdoor unit in the recess 16. Thereby, it can avoid that the external appearance of a house is impaired by installing an outdoor unit in the wall of a house. That is, even if an outdoor unit is installed, a good appearance of the house can be maintained.

In addition, since the allowable installation space for maintaining the function of each outdoor unit is known in advance by making a plurality of outdoor units installed in the recess 16 the product of the same manufacturer, the plurality of outdoor units are within the allowable range. It can be installed close to the limit. Thereby, since the recessed part 16 can be made small, even if it is a case where it has a recessed part 16, it becomes possible to ensure large indoor space in the building unit 1. FIG. Further, by arranging a plurality of outdoor units close to each other, more outdoor units can be installed in the recess 16.

In this embodiment, a foundation such as a concrete foundation is not provided under the recess 16.
