Harrison collected works by Calder and Léger and commissioned new ones for buildings that he designed, including his Long Island country house in West Hills, New York; a pavilion at the 1939 New York World's Fair; parts of Rockefeller Center; and the United Nations headquarters. Léger waited out part of World War II by painting a mural at the bottom of Harrison's swimming pool. Léger also created a large mural for the home's circular living room and sculpted an abstract form to serve as a skylight. Calder's first show is said to have taken place at the home. In 1965, Harrison was appointed to a commission to choose modern art works for the Governor Nelson A. Rockefeller Empire State Plaza Art Collection in Albany, NY.
