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.
