Besides the furniture, the pavilion exhibited a model of his 'Plan Voisin', his provocative plan for rebuilding a large part of the center of Paris. He proposed to bulldoze a large area north of the Seine and replace the narrow streets, monuments and houses with giant sixty-story cruciform towers placed within an orthogonal street grid and park-like green space. His scheme was met with criticism and scorn from French politicians and industrialists, although they were favorable to the ideas of Taylorism and Fordism underlying his designs. The plan was never seriously considered, but it provoked discussion concerning how to deal with the overcrowded poor working-class neighborhoods of Paris, and it later saw partial realization in the housing developments built in the Paris suburbs in the 1950s and 1960s.
