The 1946 Wallace Neff, “Shell House,” is his most significant contribution to the field of architecture. Neff was a true pioneer of the “ferro-cement” substrate, still in it’s infancy.

The east entry ‘eyebrow’ did not have enough steel to suspend the weight of the concrete. The armature was re-built, a closed cell foam was poured into a fiberglass plywood form, instead of concrete. The fiberglass plywood form became part of the finished product. The finished surface was then fiber glassed and then ‘canvas air balled’ to match the existing surface texture.
