One of the great historic Purchase estates, this prime sub dividable 15-acre property offers idyllic seclusion PLUS an outstanding development opportunity. It can be subdivided into a number of building lots. The grand English manor house, built in 1917, was designed by renowned architects Carrere & Hastings – famous for the NY Public Library and the Standard Oil company buildings, among others. Beautiful original features include hardwood floors, sculpted marble fireplaces, and an exquisite circular stairway. Magnificent high-ceilinged formal rooms with multiple French doors open onto expansive terraces, a brick loggia, and rolling lawns. Other highlights include the opulent billiards room, and an all season sunroom with three walls of arched doors and windows. A light-filled guest suite/studio with separate entrance is ideal for a home-based business. Still owned by the original family, this superb property is a slice of New York history. A once-in-a-lifetime ownership opportunity!
