Since 1902, 165 East 70th Street has held court on New York City’s Upper East Side, when it was first constructed as a carriage house and stable by renowned architect, C.P.H. Gilbert, for banker Henri P. Wertheim. The limestone Neo-Italian Renaissance structure was built exceptionally wide (33 feet by 100 feet, to be exact), in order to provide everyday access to transport via horse and carriage. In 1920, the home was converted into chauffeur’s quarters for Stephen C. Clark, heir to the Singer Sewing Machine fortune, before being purchased by banking heir Paul Mellon and his wife, Bunny, in 1965.
