Part of a series that aims to place buildings within their historical context, this text considers Gropius' Dessau Bauhaus, Le Coubusier's Unite de Habitation and Kahn's Salk Institute. It includes specially produced technical drawings that explain how the buildings were detailed and put together. The text explains how all three buildings are the product of great social vision and humanism and that by studying these pivotal buildings together, the approaches of three different architects to building for specific communities can be examined.
