Set across nearly four acres on Sagaponack's most exclusive oceanfront street, this estate represents an unprecedented opportunity to acquire a fully realized, turn-key masterpiece in one of the Hamptons' rarest locations. With more than 360 feet of sweeping Atlantic frontage and complete seclusion at the end of a private lane, the property offers a setting of unmatched privacy, serenity, and prestige. The residence is the result of an extraordinary collaboration between leaders in architecture, construction, landscape, and interior design. Robert A.M. Stern Architects, a globally respected firm recognized for excellence, craftsmanship, and enduring architectural language, who also guided key elements of the home's interior vision. Bulgin & Associates, renowned Hamptons builders known for impeccable detail, brought the design to life with exceptional integrity. The interiors were further refined with contributions from Mark Epstein Designs, known for sophisticated, art-informed spaces. Ed Hollander, celebrated for serene, place-driven landscapes, completed this masterpiece. Together, this team has created a home of absolute integrity, elegance, and enduring Hamptons character. Spanning 9,500 square feet, the interiors unfold as a sequence of refined, light-filled living spaces oriented toward the ocean. The heart of the home is an expansive great room with 15' cathedral ceilings - an architecturally significant space with multiple seating areas, a dining area, and fireplaces that bring warmth and sophistication. The elevated, open-format custom kitchen designed with dual islands for both cooking and gathering, serves as a central family space. An oceanfront breakfast nook and an adjoining sitting area with a fireplace create a warm, inviting environment. The oceanside primary suite offers a serene private retreat, complete with a stunning custom office and sweeping Atlantic Ocean vistas that frame each moment. The home is thoughtfully designed to accommodate guests with a collection of beautifully proportioned en-suite bedrooms and inviting lounge spaces. Dedicated wellness amenities provides a spa-like experience, including areas for Pilates, treatments, and restorative relaxation, while a light-filled gym captures the rhythm and serenity of the ocean. Additional recreation and game areas offer refined spaces for gathering and leisure. Across the home, verandas, terraces, and ocean-facing rooms blur the boundary between interior comfort and the surrounding landscape, reinforcing a sense of calm, connection, and coastal luxury. Outdoors, the estate continues to impress with 2,000 +/- square feet of covered porches, a rare luxury in Sagaponack. An oceanside pool and spa, expansive terraces, a Har-Tru tennis court, and sweeping lawns that roll toward the dunes create a resort-like environment, complemented by multiple covered and open-air spaces ideal for elevated entertaining. The neighboring estate spans over 60 acres of land, reinforcing the property's unparalleled scale, privacy, and protected views. This is not simply an oceanfront home-it is a world-class beachfront estate, built to the highest standards. A turn-key Hamptons retreat of this caliber, on a street of this pedigree, is exceptionally rare.
