ABSTRACT:
A folding building structure has a fixed roof formed by joining a plurality of identical triangles which have two equal side edges, a base edge and an apex opposite the base edge. All these apexes meet at a common point. To each roof base edge is hingedly joined the coextensive base edge of a wall triangle having two equal side edges. Each side edge of a wall triangle has hingedly joined thereto the hypotenuse edge of a right triangular wall panel. Each right triangular wall panel has a side edge equal to the height of the wall triangles having two equal side edges, and adjacent side edges of the right triangular wall panels are hingedly joined.
