A armchair is a machine to sit down. the washbasins are machines to wash. The world of our task has created its things: the clothes, the fountain pen, the blade to shave, the typewriter, the telephone. the limousine, the steamer and the airplane. " Thus, then, it was absolutely necessary to also create a new architecture, and it founded it to Le Corbusier around five basic points: use of pilotis (sustenation elements), gardens in the tile roof, free conformation of the plants, continuous large windows and frees formation of the facade, all this within a strict geometric order like unique generator of " volumes puros". These solutions would happen to be the fundamental and paradigmatic characteristics of the architectonic rationalism.
The utopia of Le Corbusier was to create a new urban reality, a city that outside a synthesis between nature and technological development. For it, architecture and urbanism had to be perfectly integrated. Le Corbusier conceived urbanism like interaction of the space of the civilization in the space of the nature and its ideal city, projected in 1922, it is constructed in vertical, leaving free great zones of the surface of the ground, that become green zones to reason below the buildings. These rise on pilotis, leaving the ground floors like spaces of free communication. The tile roofs, turned into gardens, stop being useless spaces; the streets are of ample dimensions and the traffic is organized in great routes of fast circulation, net separated of the zones for pedestrians. Before the chaos of the great centers urban, incapable to absorb the unstoppable agglomeration of vehicles and people, Le Corbusier dreamed a city of skyscrapers connected by gardens and freeways, but their dreams were only of paper and, although it projected tens of skyscraper, never constructed no. In the Twenties, it even had to be satisfied to the construction of isolate houses; one of these, that have happened to history like magnificent example of the corbuseriano rationalism, is the Ville Savoye (1928-1929, Him Possy), an application of the house sustained by pilotis, related to the outside through great cristaleras and the connected nears space.
