A structure includes a frame formed of a flexible endless band in an arched figure eight. The band includes roof sections extending from the cross-over point, wall sections extending from the roof sections and foot sections each extending between two of the wall sections. The band has a permanent deformation which may be an abrupt angle at each position between the roof sections and the wall sections. Sheet material extends across the loops of the figure eight frame, between adjacent roof sections to form a pitched roof and between at least three adjacent wall sections. A retainer at the cross-over point in the figure eight is attached to the endless band at two opposed positions and has a fixed position retaining the band at the two opposed positions fixed together. It may have a release position retaining the band at the two opposed positions rotatable relative to one another. The resilient endless band is collapsible into a configuration with six overlying coils. A rigid brace extends from one portion of the band forming one loop to another portion of the band forming the other loop.

[ What is claimed is:] [1.]1.
