Since the side panels 21A, 22A, 21B are engaged by the lower frames 11A, 12A, 13A, the side panels 21A, 22A, 21B can be securely fixed to the lower frames 11A, 12A, 13A. Further, the side panels 21A, 22A, 21B are fitted to each other by the stepped portions 21c, 22c and the recessed grooves 22d, so that the side panels 21A, 22A, 21B can be securely fixed by the lower frames 11A, 12A, 13A.

In this embodiment, the second side panel 22A and the third side panel 21B are connected along the X direction. However, it is not always necessary to provide two side panels along the X direction in this manner, and only the second side panels 22A may be arranged at both ends of the first side panel.
In this case, as shown in FIG. 11, the knockdown residential unit 100A can employ a second side panel 22B that is longer in the X direction. Also, the first side panel 21A and the second side panel 22B may be assembled using the first lower frame 11A and the second lower frame 12A. However, it is preferable to use the third frame 13 as the second lower frame 12A used in this case.

It should be noted that the present invention is not limited to the above-described embodiments, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, numerical value, form, number, location, etc. of each component in the above-described embodiment are arbitrary and not limited as long as the present invention can be achieved.

For example, in the above embodiment, the third side panel 21B has the same configuration as the first side panel 21A, and the first side panel 21A can be used. The first side panels 21A are not necessarily identical. For example, the first side panel 21A and the third side panel 21B may differ only in the position, number, shape, etc. of the through holes.

Further, in the above embodiment, the first upper frame 11B, the second upper frame 12B, and the third upper frame 13B are respectively the first lower frame 11A, the second lower frame 12A, and the third lower frame. Although it has the same configuration as 13A, it does not necessarily have to be the same.

Furthermore, in the above embodiment, the mounting grooves 11c, 12c and 13c are provided with the engaging projections 11e, 12e and 13e, and the first to third side panels 21A, 22A and 21B are provided with the engaging grooves 21b and 22b. However, the present invention is not limited to this, and engagement grooves may be provided in the mounting grooves 11c, 12c and 13c, and engagement projections may be provided in the first to third side panels 21A, 22A and 21B.
