Roche's firm has been responsible for devising and executing a masterplan which almost doubled the floor are of the New York Metropolitan Museum of Art in Central Park.

C. Douglas Dillon, Chairman of the Metropolitan Museum of Art, which has several important new wings and additions designed by the Roche-Dinkeloo firm, said in an interview published in the AIA Journal, "They did a great design that is perfect for art. They were not out for the enshrinement of their own very real genius."
