Abstract: An underground house includes a dome-shaped structure disposed on a solid floor slab. A plurality of curved arch members extend from the floor slab to a ring structure. A layer of stiff mesh supporting a layer of fabric extends between each arch member and the arch members adjacent thereto. Alternate layers of spaced horizontal and vertical reinforcing rod extend over and generally parallel to the fabric and are supported by the various arch members. The various pieces of reinforcing rod are tied together and to the adjacent mesh by pieces of tie wire to support the mesh and the fabric. The fabric provides support during construction for a layer of gunnite or shotcrete into which various pieces of the reinforcing rod are embedded. Front and rear atriums with vertical, semi-cylindrical walls extend to the lower floor level. The atrium walls extend to adjoin the layer of gunnite to laterally enclose the atriums.
