The Skinny: One of Washington D.C.'s most pedigreed mansions has come up for sale for the first time in more than half a century, but has been listed for a very contemporary price, $26M. Designed in 1901 by the legendary architect Stanford White, the 36,000-square-foot limestone pile was built for Nellie and Robert Patterson—she was the daughter of newspaper mogul Joseph Medill and he edited the Chicago Tribune. In 1927, the Patterson's daughter loaned the house to President Calvin Coolidge, who lived here while the White House was undergoing renovation. For the past 52 years, the 16-bedroom mansion has been owned by the Washington Club, but now that the club is disbanding, the property has been hauled onto the market, with brokers hoping an embassy or foundation will come along to use this oversized house as a headquarters.
