About this property
This is not simply waterfront living. This is a waterfront lifestyle unlike any other. Tucked within the coveted enclave of Sachem's Head, this extraordinary estate commands direct Long Island Sound frontage with unobstructed harbor views and breathtaking sunsets. Masterfully crafted in 2003 and transformed by the current owners with uncompromising quality, the 6,000 SF+ residence is defined by Dramatic walls of glass framing endless water views from virtually every room offering seamless indoor-outdoor living. You will be immediately wowed by the jaw dropping great room with an incredible fireplace & soaring ceiling. At the heart of the home lies a stunning Poliform kitchen, the pinnacle of modern luxury, thoughtfully appointed with premium appliances and designed to delight the most discerning chef. Oversized dining area that effortlessly steps right onto the expansive Ipe deck for additional outdoor waterfront entertaining. The all glass-enclosed family room overlooks the sound as well as the heated saltwater pool. Upstairs, a dramatic suspended gallery leads to an octagonal office and private outdoor captain's walk with endless vistas. The primary suite is a sanctuary with panoramic water views, balcony, fireplace, custom closets, and a spa-inspired bath with oversized shower and infrared sauna. A separate wing offers three en-suite bedrooms with stunning new baths and custom bunks for additional guests. Exceptional boating amenities include a permanent pier of concrete
