Location: New York, N.Y. Price: $46,000,000 The Skinny: This 40-foot-wide Neoclassic French townhouse on Manhattan’s Upper East Side possesses a level of grace, charm, and sophistication that only a residence custom-built for a woman who redesigned the White House Rose Garden for her friend Jacqueline Kennedy could achieve. Bunny Mellon (famed horticulturist, member of the International Best Dressed List, granddaughter of the inventor of Listerine) and her husband Paul (heir to the Mellon banking fortune, one of five national designated “Exemplars of Racing”) had the 11,000-square-foot, 14-room mansion built in 1965, to—and this is something of an understatement—exacting standards. The house, which features three exposures, and a garden with a reflecting pool, last sold in 2006 for $22.5M and now finds itself back on the market for $46M, because sure, why not. Thankfully, not much seems to have changed, save, perhaps, an updated kitchen, since the Mellons’ heyday.
