A portable multiuser sauna includes an enclosure configured as a truncated, regular icosahedron with ten sidewall triangular structural panels and five rooftop triangular structural panels, wherein each sidewall triangular structural panel is compressively coupled to at least two adjacent triangular structural panels.

A foldable building structure is provided that includes a fixed space portion including a first floor portion, a first ceiling portion, and a first wall portion. The structure includes a second ceiling portion and a third ceiling portion each movable between a folded position that is proximate to the fixed space portion and a deployed position. The second and third ceiling portions are movable from their respective folded positions to their respective deployed positions to form with the first ceiling portion a ceiling component of the building structure when in their deployed positions, the ceiling component having a periphery. At least one of the first floor portion, the first ceiling portion, the second ceiling portion, or the third ceiling portion includes at least a section of a closed-loop passageway proximate to the periphery in the interior portion adapted to contain a utility line.

A compactable and portable shelter can include side panels, front and rear panels roof panels and a spine panel that are hingedly connected by continuous hinges in a manner that enables the panels to collapse onto each other and into a small profile unit for ease of transport, deployment and recovery. A window and door can be formed in at least one front or rear wall panel. Support brackets can hold wall panels upright at ninety degrees with respect to floor panels. A solar power system can provide electrical power for lighting and electronic device charging to occupants of the shelter. Adjustable legs connected at exterior corners of the base can level the left base flow panel and the right base floor panel. Panels can be thermally insulated.
