Le Corbusier's ideas for city planning focused on large, tall, residential buildings that would each constitute an entire neighborhood. He successfully tried out his idea on modern middle-income housing, but these ideas were criticized by those arguing that his vision for urban life was destructive to the city, alienating people from one another, and elevating the car and the machine over the human. For decades, Le Corbusier tried to get Paris to raze the Marais neighborhood and build one of his city plans. It was his project in Marseilles, “unité d'habitation” that substantiated this vision. Developed in 1945 and commissioned for the rehousing of people left homeless by the war, it consisted of 337 apartments assembled on a reinforced concrete frame with interiors designed by Charlotte Perriand.
