ABSTRACT:
A foldable construction element for forming roof constructions or buildings is described. The foldable element may consist of a polygonal sheet of paper, cardboard, plastic, or other suitable material which is provided with fold-lines in selected areas thereof. The sheet of material is selectively folded along the fold-lines to form a roof construction or building structure of a desired shape. The folded structure may be reinforced by a coating or layer of any suitable material to provide added structural strength to the final construction. Many shapes of the fold-lines, relative, sizes, and orientations can be chosen to form buildings or roof constructions of selected shapes. Methods are described for the controlled folding of the construction elements for either on or off site assembly of the building or roof construction. Foundation systems are also described for use with the folded construction elements.
