His later architectural work was extremely varied, and often based on designs of earlier projects. In 1952–1958, he designed a series of tiny vacation cabins, in size, for a site next to the Mediterranean at Roquebrune-Cap-Martin. He built a similar cabin for himself, but the rest of the project was not realized until after his death. In 1953–1957, he designed a residential building for Brazilian students for the Cité de la Université in Paris. Between 1954 and 1959, he built the National Museum of Western Art in Tokyo. His other projects included a cultural centre and stadium for the town of Firminy, where he had built his first housing project (1955–1958); and a stadium in Baghdad, Iraq (much altered since its construction). He also constructed three new "Unités d'Habitation", apartment blocks on the model of the original in Marseille, the first in Berlin (1956–1958), the second in Briey-en-Forêt in the Meurthe-et-Moselle Department; and the third (1959–1967) in Firminy. In 1960–1963, he built his only building in the United States; the Carpenter Center for the Visual Arts in Cambridge, Massachusetts.
