About This Home
Set on a perfectly scaled .36-acre parcel, this newly constructed modern barn offers 4,333 +/- SF of thoughtfully curated living space, leading the charge with a new Hamptons design.

Soaring 12' ceilings throughout create an airy elegance, while walls of glass invite in natural light and frame tranquil harbor views. The main level is designed for effortless entertaining; a seamless open layout connects the chef's kitchen, dining area, and living room. Clean architectural lines lead into the outdoor living spaces, where a heated pool and spa are surrounded by lush, manicured grounds. The home features five well-appointed bedrooms and five-and-a-half baths, including a serene primary suite with water views, a private terrace, and a spa-like bath. A second-floor terrace offers sweeping vistas, while the lower level is tailored for relaxation and recreation, complete with a bunk room, private gym, sauna, and a temperature-controlled wine room. A 2-car garage with extended height and depth offers flexibility for a golf simulator or additional lifestyle use. Ideally positioned just minutes from East Hampton Village and directly across from Gardiners Marina, with easy access to Three Mile Harbor, this location offers the best of waterfront living, close to beaches, boating, and the Hamptons' most coveted dining destinations. Outdoors, multiple lounging and entertaining areas create a true resort-like setting, equally suited for summer gatherings or quiet coastal evenings.
