Abstract: A one-story building having a concrete foundation, a wooden roof and interior and exterior walls of precast concrete panel construction, the walls being formed from precast concrete panels and installed in place without benefit of rigid interconnecting joints therebetween. Additionally, the wall panels are connected to the foundation at their bottom ends, and to the wooden roof at their upper ends, by means of nonrigid, as opposed to rigid, connection. Each of the exterior wall panels has an inner, structural slab of steel-reinforced concrete, a thin intermediate layer of a compressive, insulative material and an equally thin outer layer, or skin, of wire-reinforced concrete. The interior walls of the building are interrupted by door openings, or the like, to permit expansion and contraction of each wall segment as an independent unit. Because of the lack of rigid structural ties between the separate panels of the building walls, and between the wall panels and other parts of the building, each of the panels is free to move independently without creating strains in the overall structure that could lead to cracking or spalling of its walls. Also, the intermediate layers of compressive, insulative material in the exterior wall panels cooperate to form a pliable cocoon around the structural inner portion of the exterior wall shell which serves to insulate that portion of the shell from ambient temperature extremes and cushions the outer skin from the force of movements within the wall proper.
