For fans of fab prefab: is a good resource on moderne prefab dwelling. Their list of prefab is insightful.

Predominant mass-market housing programs such as project homes or tract housing largely fail to meet the desires of people who appreciate a modernist design aesthetic. Custom-designed modernist architecture is beyond the financial reach of many people and so prefab is viewed as a design and production ideology that has the potential to deliver affordable modernism. While kit or prefab homes have been available in a range of either "traditional" or "alternative" forms for many years, surprisingly few prefab homes exist that truly embrace modernist ideals.

Modernist prefab is still more of a meme than a marketplace. Most projects are “in development” and relatively few prefabs are available for immediate purchase.

While architects are clearly interested in exploring the use of prefabrication methods in design and construction, this is only one piece of the puzzle. Marketing a turn-key prefab dwelling is as much about understanding a business model as being able to design a structure. “Commercialization” is traditionally the domain of speculative builders and property developers rather than design professionals. So who will successfully bring prefab projects to market? What forms will winning business models take?
