About this home

Anchored on the Atlantic.... The essence of Hamptons coastal luxury awaits on coveted Dune Road, just moments west of the Jessup Lane bridge. Perfectly positioned between the serene waters of Moriches Bay and the Atlantic Ocean, this extraordinary custom-renovated contemporary offers a rare opportunity to experience one of the most coveted lifestyles in the Hamptons—where every day begins with ocean breezes and ends with unforgettable waterfront sunsets. Set on .52 private acres with exclusive ocean access via your own private pathway to the beach, this spectacular 3,797-square-foot residence seamlessly blends sophisticated design with effortless coastal elegance. Featuring five luxurious ensuite bedrooms, five full baths, and one half bath, every bedroom is thoughtfully designed to capture breathtaking water views and opens to private decking, creating a seamless connection between indoors and out. Designed for elevated entertaining and relaxed seaside living, the chef’s kitchen is beautifully appointed with a Viking six-burner range with grill, Miele dishwasher, built-in Miele espresso station, wine cooler, Library/Media room with 80 inch TV, and exceptional custom finishes throughout. Crowning the home is an extraordinary rooftop deck with panoramic 360-degree views of both bay and ocean—an unrivaled setting for sunrise coffee, sunset cocktails, and stargazing under endless Hamptons skies. Luxury details abound, including copper gutters, central air, Kohler whole-house generator, and integrated Sonos sound system, ensuring both comfort and peace of mind year-round. Outdoor living is nothing short of spectacular. Expansive mahogany decking, lush professional landscaping, elegant new teak furnishings, and a beautifully refurbished heated gunite pool create a private resort-like setting designed for unforgettable summer gatherings or quiet moments of retreat. Offered fully furnished and professionally designed, this turnkey masterpiece embodies the very best of Hamptons living— where private ocean beach access, watching boats on Moriches Bay, and world-class dining in nearby Westhampton Beach become part of your everyday life. This is more than a home—it is Dune Road living at its finest.
