Nimrod Regev is an architect working on residential and public projects. His professional education was acquired at the Technion Faculty of Architecture. Nimrod worked as an architect at Moshe Zur architects, Jacobs Yaniv architects and is now an architect at Potash architects, where he works on large public and academic structures. On 2019 he started consulting in a Technion course titled “housing for the masses”. .Impact! Mass Housing as the Cornerstone of Bauhaus Contribution to Future Design Methods. * This paper discusses Bauhaus’ impact on the future of design by examining its key role in the formation of four design strategies developed to meet the problem of mass housing. Mass housing was first regarded as a problem for professional designers in the modern context of the industrial city. Yet it was in interwar Bauhaus where housing was first articulated as the centre of all design problems—from the city to the building, to the chair. Bauhaus teachers and students saw housing as an extreme design problem, through which architects and designers developed new design methods for meeting the demands of affordability, functionality, varied needs, and mass production. In this paper , we identify four key design methods articulated for mass housing in the interwar period, and their changes and re-articulation over time: (a) Design rigour; (b) Disassembly and reassembly; (c) Seriality vs. replication; and (d) Democratic design. Our paper opens with a theoretical and technological mapping of the four design methods as articulated in design manuals, syllabi, and designed objects. Afterwards, we trace the evolution of the four methods over time by examining their design articulations in four key periods of modern housing: interwar modernism, post-WW2 mass housing, experimental Avant- garde futurism (1960s–1970s), and contemporary design explorations. The four design methods exemplify Bauhaus’ impact as a modern design laboratory. Likewise, they limn more modern approaches to similar problems, like the move to kit furniture and kit housing.
