Prefab homes are catching on now as a new normal building technique, but the trend was also popular in the '40s with Lustron houses, steel prefab homes for returning WWII veterans. The homes are completely made of porcelain-coated stainless steel, can be cleaned with a power hose, don’t require paint, won’t be damaged by termites, and are immune to decay, rust, and rodents, says Realtor.com's Claudine Zap.

The concept began as a quick way to assemble homes for returning war veterans in the mid-1940s. An Ohio factory mass-produced 3,000 parts per home using 12 tons of steel, including the bathtub, cabinets, and vanities, which were then loaded onto a truck and assembled on-site in less than a week. The company closed in 1950 after producing only 2,500 homes. But a few of these homes still stand today and are even on the market.
