A brand-new architectural masterpiece on Sag Harbor Cove in the enviable Bay Point area of Sag Harbor, thoughtfully designed by the world-renowned Turkel Design. This striking waterfront residence spans 4,050 +/- SF and is meticulously crafted to harmonize contemporary design with its extraordinary natural setting. A dramatic two-story foyer opens into an expansive open-concept great room, where walls of floor-to-ceiling glass frame uninterrupted panoramic water views. The chef's kitchen is both refined and functional, featuring marble waterfall countertops, custom cabinetry, a butler's pantry, and a premier suite of professional-grade appliances by Wolf, Sub-Zero, and Bosch designed for both entertaining and everyday luxury. The home offers 5 beautifully appointed bedrooms and 5.5 baths, including a serene first-floor junior primary suite and a showstopping upstairs primary retreat. Here, a sleek freestanding soaking tub sits before a wall of glass, delivering breathtaking views over Sag Harbor Cove and creating a spa-like experience unlike any other. Outdoors, the residence transforms into a private waterfront resort. A free-form saltwater gunite pool and spa are surrounded by expansive tallowwood decking, anchored by a wood-burning fireplace overlooking the water. Indigenous landscaping enhances privacy, while a brand-new bulkhead and private dock place boating, paddleboarding, and coastal exploration right at your doorstep-offering effortless access to the bays, coves, and waterfront destinations of Shelter Island and the North Fork. Modern systems and smart-home features elevate comfort and peace of mind, including a 4-zone dual-hybrid heat pump system, heated bathroom floors, power window shades, solar panels, a whole-house generator, and an attached two-car garage with mudroom access.
