Piee and Eugénie Savoye approached Le Corbusier about building a country home in Poissy in the spring of 1928. The prospective site was a green field on an otherwise wooded plot of land, with a magnificent view of the landscape to the north west that matched the approach to the plot along the road. Other than an initial brief prepared by Emile for a summer house, space for cars, an extra bedroom and a caretaker's lodge, Le Corbusier had such freedom in executing the commission that he was limited only by his own architectural aesthetic. He began work on the project in September 1928. His initial ideas were ultimately manifested in the final building, though between Autumn 1928 and Spring 1929 he drew up a set of alternative designs that were governed primarily by the Savoye couple's concerns regarding cost. The eventual solution to the cost problem was to reduce the volume of the building by moving the master bedroom down to the first floor and reducing the grid spacing from 5 metres to 4. 75 metres.
