Like Walter Gropius, who saw housing as a mass demand that could be satisfied only by mass production, most architects of the Modern Movement regarded industrial prefabrication as the solution to the major problems of their time. “Housing for everyone” was the slogan after the First World War, and it was mainly for social reasons that planners advocated serial production and the rationalization of building. Euphoria for the automobile and the methods used in its manufacture suggested parallels in the fabrication of housing.
