The Lustron homes were built in the 1950's by Chicago based Carl Strandlund. After World War II, Carl obtained government loans to produce homes of steel with porcelain coated exterior panels, steel framing and steel interior walls and ceiling. He founded the Lustron Corporation and built approximately 2,498 Lustron Homes in a former aircraft plant in Columbus, Ohio. The Lustron homes were designed to be maintenance free and were produced in 1949 and 1950. These homes were considered to be three times stronger than a traditional stick built home and were advertised as being rodent proof, fire proof, lightning proof and rust proof.
