This handsome Fifth Avenue mansion, prominently located at the southeast corner of Eighty-second Street, was built during the years 1899 to 1901. It is one of the few surviving houses which once formed part of an almost uninterrupted series of palatial residences facing Central Park. In recent years the majority of these grand townhouses have fallen victim to rising property values, and have been replaced by apartment buildings. No. 1009 is exceptional, as it remained in the possession of the Duke family, the original owner, until 2006 and remains a single-family home. Today it provides us with a fine example of turn- of-the-century architectural opulence.
