Abstract: A frame structure defines a space capable of accommodating a user, and includes a plurality of outline frames that forms an assembly-type framework for the space, a sheet that is stretched over the framework so as to form a floor surface, a side surface, and a top surface of the space, a support frame that supports the floor surface at a position higher than a base surface where the frame structure is placed, a battery attachment portion that enables attachment of a battery to an under surface side of the floor surface, an outlet provided on any of the floor surface, the side surface, and the top surface, and a battery connecting portion that connects the battery attached to the battery attachment portion and the outlet.

Abstract: A space structure with an interior space, the space structure having a plurality of hexagonal planes and a plurality of triangular planes surrounding the space, in which each of the hexagonal planes and each of the triangular planes are arranged so as to face each other with the space S in between, and, when the space structure is installed so that one of the plurality of hexagonal planes is a bottom surface, other hexagonal planes slope toward the space S side as the other hexagonal planes go from bottom to top.
