They gracefully lead the way to a serene 20x50 saltwater gunite pool that is complemented by a spacious, elegant pool house. Sports enthusiasts will appreciate the lighted clay tennis court and a heated, enclosed outdoor structure, perfect for squash or basketball. Adding to the estate’s appeal, a charming three-bedroom, two-bath guest cottage provides comfortable accommodations, while a three-car heated garage with a separate workroom ensures ample space for vehicles and storage.
