Armco-Ferro House at Indiana Dunes National Lakeshore
The Armco-Ferro House is the only remaining house from the fair that met the Fair Committee's design criteria; a house that could be mass-produced and was affordable for the average American family. This seemingly frameless house boasts a revolutionary construction system: corrugated steel panels that are bolted together. This system resembles a typical cardboard box; it could be placed on its bottom, side, or top without damaging the structure. The corrugated panels are clad with porcelain-enameled steel panels produced by the Ferro Enamel Corporation. This construction system later provided the inspiration for the post World War II prefabricated housing developed by the Lustron Corporation. Several Lustron houses can still be seen in Beverly Shores.
