The Benjamin N. and Sarah Duke House, also called the Duke–Semans mansion (pronounced / /), is located at 1009 Fifth Avenue in New York, New York. The building was built in 1901. The house was owned by the Duke family until 2006 when they sold it for $40,000,000 to real estate billionaire Tamir Sapir. Carlos Slim, at the time the richest person in the world, bought the mansion four years later in 2010 for $44,000,000.
Built for Benjamin Newton Duke (1855 – 1929), the Benjamin N. Duke House is one of the classic Fifth Avenue townhouses. Two of Duke's neighbors were Vanderbilts, but both of those mansions were torn down in the 1920s and 1930s. When Duke died in 1929, his children inherited the house, who kept it in the family for another 77 years until they sold it in 2006 to Tamir Sapir, who then sold it to Carlos Slim in 2010 for $44,000,000. Slim has said in a recent interview with CNBC that he is planning on using the house as a place to stay when he is in New York for business.
Designed by Alexander M. Welch, the house was built in 1901 in a Beaux-Arts style with French Renaissance interior, decorated mainly with Louis XV furniture. The house is eight stories high, 20,000 square feet and measures 100 feet wide, and 27 feet deep. The mansion also has a private staircase on the top floor that leads to a rooftop balcony. The builders were so ingenious that they even put closets in the same spot in the home on every single level so that when elevators were developed contractors could remove the closets, build elevator shafts, and install the elevators. Benjamin's brother James Buchanan Duke (1856–1925) also built a townhouse on Fifth Avenue, the James B. Duke House, which was designated a New York City Landmark in 1970, and added to the National Register of Historic Places in 1977.
