ABSTRACT
Le Corbusier's contribution to urbanism during the period following World War II can be characterised as having two great traits: a poetical trait and a theoretical trait. In Le Corbusier's view, the three types of human establishments, that is, settlements that are essential to man, are: the unit for agricultural production; the linear industrial city; and the radio concentric cities of exchanges. Le Corbusier's discourse on the three human establishments can be found in the linear industrial city, the Saint-Dié plan. It is developed as a result of Le Corbusier's reflections on the city, the territory and transports, and emerges as a solution to the suburbs. Le Corbusier, in fact, built only one housing unit with a rooftop such as the one he had designed. However, there were several housing unit projects where Le Corbusier sought to include the design of the rooftop-terrace similar to that of the Marseille Housing Unit.
