The palatial owner’s suite includes a fireplace, sitting room, and exquisite bath. There are two additional guest suites, a Nanny/Chauffeur ensuite quarters, and a private guest house with kitchenette. The living room and family room are enhanced with tremendous views. A beautiful dining room with hardwood floor allows access to the rear grounds and patio. The gourmet eat-in kitchen offers granite counters, Subzero and high-performance appliances. A long private driveway leads to a sweeping circular approach to the home and 4-car garage. Important features include: A 10 year old roof, copper plumbing, 3 A/C units, laundry room, and wonderful mature landscaping. This is a chance to own a one-of-a-kind home designed by a man honored in American History, architect Paul Williams. Thank you for coming.
