A refoldable and transportable rigid building which requires no load bearing interior walls and further permits the permanent placement of plumbing and plumbing fixtures almost anywhere within the periphery of the exterior walls. Upon unfolding, the structural components of the building become fast on one another providing a rigid building which is capable of resisting substantial racking and compression stresses without loss of integrity. Folding and unfolding of the building may be accomplished with the use of hand tools only. A sixty per cent volume reduction is achieved on folding and when folded the structure may be handled by a forklift and/or supported on a pair of dollies.
