Abstract: A construction method for fabricating structures and a system of building blocks utilized in the method is presented. The blocks are skeletal and formed from heavy gauge rods or bars with straight and hook projections that permit the blocks to be interconnected. Recesses are provided in the blocks so that an assembly of blocks will accommodate furring strips or stringers which will add to the structural integrity of the block structure and provide a nailing surface.
