The Georgian estate dates back to 1680. It was built for the Cocks, a farming family. The 27-room manor sits on 11.4 acres of rolling lawns and rose gardens. Two huge bushes at the front entrance have been there since before the American Revolution, says Patrick Mackay of Piping Rock Associates. The house also has six bedrooms, 9.75 bathrooms, a two-story columned porch, decorative moldings throughout the house, fireplaces in the living room, dining room and library, and a large solarium. It is listed at $7 million with Piping Rock Associates, Locust Valley.
