  As shown in FIGS. 3 to 5, the building unit 1 has a recess 16 configured to be recessed on the indoor side. The recessed part 16 is provided in the floors other than the top floor of a house, and is provided in the 1st unit 11 which comprises a first floor part in this embodiment. In addition, the recess 16 is provided so as to recess a part of the outer surface of the first unit 11. Specifically, the recess 16 is provided so as to dent the remaining portion of the outer side surface of the first unit 11 except for the pair of side walls 18 b facing the upper portion 18 a. The amount of recess (the amount of retraction) to the indoor side in the recess 16 is, for example, 600 mm.

  The recessed part 16 is comprised by the frame of the building structure 11a. Specifically, the recess 16 is formed by providing a part where there is no shaft set and floor set in a part of the building structure 11a. In addition, in the building unit 1, the outer side surface in which the recessed part 16 was formed is a surface of the outdoor side. That is, the outer wall is provided on the inner surface of the recess 16.

  And an outdoor unit is installed in crevice 16 constituted in this way. Specifically, as shown in FIGS. 3 to 5, the air conditioner outdoor unit 42, the water heater 60 and the power storage device 70 are accommodated in the recess 16 so as to be accommodated in the space of the recess 16. . Thus, the recessed part 16 can be used as a space for installing the outdoor unit of a housing installation. In the present embodiment, all the outdoor units connected to the equipment incorporated in the building unit 1 are disposed in the recess 16. In addition, installation to the recessed part 16 of an outdoor unit is performed at a construction site, for example.

  Thus, the building unit 1 in the present embodiment has the recess 16 in which the outdoor unit is installed. Thus, when the building unit 1 is installed on a housing construction site, an outdoor unit can be installed in the recess 16. Therefore, the vacant 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 next house, the outer wall of the home can be obtained by providing the recess 16 on the side next to the building unit 1 (that is, the land boundary between the home site and the next site). Since it is not necessary to install an outdoor unit in the narrow space in the site between the land and the land boundary (next house site), installing the outdoor unit outdoors can avoid narrowing the empty space between the next house . In addition, since the empty space (passageway) between the outer wall of the home and the land boundary does not narrow, maintenance of the outdoor unit can be easily performed.

  Further, in the present embodiment, an upper portion 18 a is present as an upper surface portion on the recess 16, and the upper portion 18 a functions as a canopy. Thus, even if the outdoor unit is not provided with a hood or the like, by installing the outdoor unit in the recess 16, the outdoor unit can be prevented from being exposed to wind and rain and direct sunlight, so the outdoor unit breaks down. It is possible to suppress the shortening of the life and the reduction of the functional performance.

  Further, by installing the outdoor unit in the recess 16, the outdoor unit can be hidden in the recess 16. Thereby, it can avoid that the appearance of a house is impaired by installing an outdoor unit in the wall of a house. That is, even when the 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 products 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 has a recessed part 16, it will become possible to ensure largely the indoor space in the building unit 1. FIG. In addition, by arranging a plurality of outdoor units close to each other, more outdoor units can be installed in the recess 16.

  In the present embodiment, no foundation such as a concrete foundation is provided under the recess 16. By not providing the foundation in the recess 16, the height of the building unit 1 can be used effectively. In addition, even in the case where the base is not provided under the recess 16, concrete with a degree of consolidation may be hit. That is, in order to install the outdoor unit, concrete may strike the ground of the recess 16. Alternatively, a base such as concrete may be provided in the recess 16 and the outdoor unit may be installed on this base.

  Moreover, as shown in FIG.3 and FIG.5, in this Embodiment, the recessed part 16 is provided with the door 19 which leads indoors. This allows indoor and outdoor access through the door 19.
