Transported to the Gatsby lifestyle from the Gold Coast to the Hamptons...this waterfront mansion overlooking Quantuck Bay is truly one of the grandest ever built on the East End of Long Island. This Shingled Manor exudes a sense of utmost elegance and unsurpassed style on 10.37 acres with 1,000' of water frontage. Originally designed in 1903 for William C. Atwater, a coal baron, he retained architect Henry Bacon, best known for his design of the Lincoln Memorial in Washington DC. The main house on three floors, encompassing 16,000 sf, contains 24 rooms, 9 bedrooms, 6 fireplaces, 9 full and 2 half-baths. From an entry with a three-story staircase, a reception area proceeds to a living room with fireplace and a banquet-sized formal dining room with hand-painted murals and fireplace. A large gourmet kitchen with a breakfast area, billiards room, sunroom, second-floor office, sitting room and a third-floor living room provide the ultimate in luxurious living spaces - with water views. Additional accommodations include the carriage house, with century-old grape vines, and a separate cottage. Sixty-four century-old Catalpa trees line the stately driveway and define the perimeters of this estate, while formal gardens, rolling lawns, a Lord & Burnham greenhouse, Har-Tru tennis court and a 56' gunite pool with spa tempt to enjoy the lifestyle. A deepwater dock on the bay offers excellent boating, with yacht clubs, beaches and the open Atlantic just a quick sail, kayak or motor away. NOTE: Property can be subdivided.
