1941 Prefab “Semi-Bombproof” House

1941JunePMprefabSeventy-five years ago, preparedness for war was on everyone’s mind, as shown by this prefabricated three-room house, which was erected in just 23 minutes. The sections were made of concrete which was cast in forms lying on the ground. After drying, cranes lifted them into place, and welders completed the job by welding the sections together. The house was said to be “semi-bombproof,” meaning that it would “stop all but the heaviest flying fragments.” It was designed as quick construction of housing for defense workers.

The company making these, Thermo-Crete Homes, 10846 Ventura Blvd., Los Angeles, California, also made a small A-frame bomb shelter for use in backyards.

The house appeared in the June, 1941, issue of Popular Mechanics.
