The Larchmont Post Office on Chatsworth Avenue is one of those buildings you see so often that it’s rare to give the building any more than a passing glance. But the structure, near the corner of Boston Post Road, actually symbolizes a time and place in American history when Louis A. Simon, the Supervising Architect for the U.S. Department of Treasury, was designing similar structures around the country.
Under Treasury Secretary Henry Morgenthau Jr., Simon in the mid-1930’s supervised the design of the Larchmont Post Office, which opened in 1937, as well as the one in Rye. The Larchmont building reflects Simon’s preference for Colonial Revival architecture. Simon later moved on to work for the Works Progress Administration.
