The first case of these manufactured which are reviewed in this paper.

These about today’s process of production, which shelters had timber panel floors, walls, and implies both design and fabrication with roofs.

This decision sparked much effort for architectures in post-war housing. Lustron Corporation started producing all-steel prefabricated houses in the airplane factories. The houses were simple and traditional in form. The innovation of these prefab homes was related to their construction with complete enamel steel on the interior and exterior. In 1930, Carl Strandlund who was an industrialist suggested the concept of automobile process with metal sandwich panel technology. This method was fashioned after automobile manufacturing. At the beginning, the size of manufactured sheet metals did not fit to each other which caused many wasted materials. Fig. 1. Iron Prefab [15] Thus, the cost of these prefab homes was very However, there are some unsuccessful high and the company, stopped working after experiences about prefabricated homes. As an only 2500 hours working on it, in 1950 [16, example, builder George Fred Keck designed 17, 19].
