Here's an interesting article on Prefab housing by Sarah Williams Goldhagen in the latest issue of The New Republic magazine. From the article:
Technologically, there is no reason why houses, like cars, cannot be mass-produced, and in other countries they are constructed that way.

Higher and consistent quality is more easily and reliably achieved, because the product is fabricated in the controlled setting of a manufacturing plant, with all the attendant cost advantages. The Swedish residential building industry has long been dominated by prefabricated construction: nationally uniform building systems made possible an abundance of companies manufacturing high quality kit and modular homes and prefabricated housing components. By the 1980s, prefabrication was used in 85 percent of new residential construction. (Not surprisingly, Sweden-based Ikea offers its own prefabricated house.)
