the Unité in Marseille (1945-1952) was a pioneering achievement at a time when social housing in the post WWII years posed an immense problem. Freed from restrictive regulations for the first time Le Corbusier was able to put into practice his concept of modern social housing. A milestone of modern architecture and subject of controversial debate, the Unité in Marseille continues to attract numerous visitors and students of architecture. This volume is the latest addition to Birkhäuser's series of guides to Le Corbusier's most acclaimed buildings, and includes an additional chapter on his Unités in Rezé-les-Nantes, Briey en Forêt, Firminy and Berlin. The author, a practising architect and well known le Corbusier specialist, lives in Marseille and teaches at the Ecole d'architecture de Marseille-Luminy.
