To prove that hurricane-proof homes can be built Mel Adler, president of Mel Adler & Associates Inc., Miami, recently erected a prototype all-concrete house in Homestead, Fla., that is designed to stand up to 600-mph winds as well as wind-blown debris. At the home's grand opening celebration last April, sponsored by the Florida Concrete & Products Association, Adler demonstrated his confidence in the home's indestructibility by crane-lifting a 3-ton pickup truck onto the steel-reinforced concrete roof. The home recently earned the 1995 Gold Prism Award for concrete structure design from the Gold Coast Builders Association of Southeast Florida.

No lumber was used in the home's construction. The foundation, walls, and roof of the 2,600-square-foot structure contain 250 cubic yards of 3000-psi concrete reinforced with polypropylene fibers and about 9 tons of reinforcing steel. Despite the fortresslike security offered by the concrete home, its contemporary, attractive design blends well with the traditional home styles in the neighborhood. The estimated cost of the three-bedroom home ranges from $175,000 to $250,000, depending on options added by the owner.
