Without a national or cantonal policy for the provision of affordable, so-called social housing, Switzerland`s way is unique in Europe. Finding appropriate housing is left to the people themselves. The challenge of building sustainable communities in urban centres in Switzerland has to address the tight housing market due to economic growth, immigration, and the renewed attractiveness of urban living. In the absence of a national low-cost housing policy, every growing city thus has to design its own strategies and implement local policies and programmes in order to counteract such developments. The role of housing cooperatives is important now and in the future. The paper gives an overview on the Swiss situation after the GFC and discusses the successful strategies of the provision and protection of affordable housing in the major city of Zurich.
