    What's special

    Exceptional privacy

    Set at the end of a quiet cul-de-sac between Bridgehampton and Sag Harbor Village, this expansive 4.59-acre property presents a rare opportunity to create a substantial Hamptons estate while building on an impressive collection of existing amenities. The parcel can accommodate a new principal residence and tennis while retaining the existing accessory structure, pool, and spa, providing a strong foundation for a complete private compound. Plans have already been drawn, allowing the next owner to continue the current permitting process or pursue a new design suited to the property. With generous acreage and ample space for indoor-outdoor living, the setting offers exceptional privacy, flexibility, and development potential. Despite its peaceful surroundings, the property is conveniently located near the celebrated restaurants, shops, ocean beaches, and bay beaches of Bridgehampton and Sag Harbor. Whether completing the existing vision or starting fresh, this exceptional offering provides the space, setting, and amenities to create a distinctive Hamptons retreat.
