The 1948 Calvert Manor is one of several distinctive apartment buildings designed by Mihran Mesrobian (1889-1975). Born in Turkey, Mesrobian was trained at the French-based Academie des Beaux Arts in Istanbul. His early projects include the Sheraton-Carlton Hotel, the Hay-Adams Hotel, Wardman Towers, and Sedgewick Gardens in 1920s and 1930s Washington, D.C. Between 1940 and 1950, Mesrobian designed more than a dozen apartment buildings in the expanding suburbs of Northern Virginia. Calvert Manor was built and owned by Mesrobian. The moderately symmetrical and classically organized design is enhanced by Moderne-style detail. There are occuli, raised brick courses, glass block windows, steel-hooded entries, and ornamental concrete panels. The interior public spaces at Calvert Manor feature finely designed metal stairs in the main public entrance areas.
