Panelized houses can be clad with vinyl siding, brick, or stucco, as desired. The final total construction cost, here less than $40 per square foot, is due largely to prefabrication—not only of walls, but also of kitchen cabinets, windows, and porch railings. The results are hardly "glamorous," nor is it likely that they will become so anytime soon. Colin Davies, in his excellent book The Prefabricated Home, explains why. "The strength of the prefabricated house lies in its popularity, its cheapness and the industrial base from which it operates," he writes. "These are precisely the areas in which modern architecture is weakest. Modern architecture is unpopular, expensive and divorced from industrial production. That is why whenever it has tried to extend its field to include the territory of the prefabricated house it has failed and been forced to retreat." The current generation of Modernist prefabs is unlikely to fare any better.
