ABSTRACT:
A method of constructing a shell-formed structure including the steps of first constructing a base, such as concrete slab, having a retention means defining the area of contact of the finished wall of the building with the base, the retention may be in the form of a recessed notch formed in the concrete pad, supporting a top yoke centrally above the base, positioning a plurality of spaced apart flexible slats between the base retention means and the yoke, lowering the yoke to cause the flexible slats to bow uniformly in a generally quarter circular or quarter elliptical configuration so that the bow slats generally define the exterior wall shape of the building, attaching a covering to the bowed slats, applying a layer of settable material, such as concrete, to the covering and allowing the settable material to harden to thereby form the structure.
