FORMER SHOW HOUSE: A Southampton mansion with ties to the Vanderbilt family has gone into contract. The asking price for the Great Plains Road home is $14.25 million, according to the The Corcoran Group’s website. Westlawn, the former summer cottage of Mrs. Edward Tiffany Dyer, granddaughter of tycoon Cornelius Vanderbilt, is a six-bedroom, 5 ½-bath traditional home designed by architect F. Burrall Hoffman. The mansion has been owned for many years by the family of the late businessman Emmet Blot. In 2003, the home served as the location for that year’s Hampton Designer Showhouse. The three story dwelling features a 60 foot Gunite pool and a three-car garage. The listing agent is Corcoran’s Tim Davis.
