1009 Fifth Avenue ARCHITECT: Welch, Smith & Provot DATE: 1899-1901 STYLE: Beaux-Arts 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 In recent years the majority of these grand townhouses have fallen victim to rising property values, and have been replaced by apartment buildings.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 remains in the possession of the family of the original owner, and today provides us with a fine example of turn-of-the-century architectural opulence.
