His impressive career spanned five decades, with his buildings constructed throughout Central Europe and in North and South America. He was a pioneer in studies of modern high design and was dedicated to provide better living conditions for the residents of crowded cities.
It was Le Corbusier's Villa Savoye (1929–1931) that most succinctly summed up his five points of architecture that he had elucidated in the journal L'Esprit Nouveau and his book Vers une architecture, which he had been developing throughout the 1920s.
First, Le Corbusier lifted the bulk of the structure off the ground, supporting it by pilotis – reinforced concrete stilts. These pilotis, in providing the structural support for the house, allowed him to elucidate his next two points: a free façade, meaning non-supporting walls that could be designed as the architect wished, and an open floor plan, meaning that the floor space was free to be configured into rooms without concern for supporting walls. The second floor of the Villa Savoye includes long strips of ribbon windows that allow unencumbered views of the large surrounding yard, and which constitute the fourth point of his system. The fifth point was the roof garden to compensate for the green area consumed by the building and replacing it on the roof. A ramp rising from ground level to the third floor roof terrace allows for an architectural promenade through the structure. The white tubular railing recalls the industrial "ocean-liner" aesthetic that Le Corbusier much admired. As if to put an exclamation mark after Le Corbusier's homage to modern industry, the driveway around the ground floor, with its semicircular path, measures the exact turning radius of a 1927 Citroën automobile.
All in all Le Corbusier was at his most influential in the sphere of urban planning, and was a founding member of the Congrès International d'Architecture Moderne (CIAM).
