By considering the material processes by which the Horseshoe housing estate in Berlin came into being as aesthetic vision, constructed environment and inhabited living space, this article focuses on the complex manner by which the ideas of planners and architects ‘migrate’ into actual built forms. I evaluate the roles played by emergent technologies and new building methods as well as the managerial directives of state and civic bureaucracies, assessing how co-operative and competing aesthetic visions and the life practices of inhabitants are involved in the coproduction of Weimar public housing.
