The home, defined by grand proportions, spans over 12,000 livable square feet across three levels plus a guest house. Signature elements include carved stone fireplaces, arched windows and a series of formal and casual spaces designed for both entertaining and everyday living. Amenities are extensive: a luxurious primary suite with dual dressing rooms, steam room and gym; a wine cellar with tasting room; a 10-seat theater; library and billiards room with bar; and a rare 12-car underground garage of over 3,700 square feet finished to a showroom standard. The property includes six bedroom suites in the main residence, along with a two-bedroom guest house with office, ideal for extended stays or multigenerational living.
