I began to think about relations between architects and artists on a visit to Paris. In areas like Montparnasse, there’s a concentration of stylish studio-houses around the Parc Montsouris, many of them designed by architects like Le Corbusier, Perret and Lurçat. Twentieth-century architects are often said to have ignored their clients’ wishes in order to pursue their own ideas. But could that be true in buildings which accommodated particular needs and ways of working? They made me wonder about the importance of the artist-client, and whether the studios built for them actually represented a joint project.
