About This Home

516 Asharoken Avenue

An extraordinary opportunity to own one of Asharoken’s most iconic waterfront estates. Spanning over 4,000 square feet, this custom contemporary commands approximately 220 feet of pristine, private sandy beachfront along the Long Island Sound—second only to the legendary Morgan Estate—delivering breathtaking, unobstructed 180-degree water views from nearly every room. Designed for elevated coastal living, the home showcases a sun-filled open-concept layout, anchored by a striking chef’s kitchen with custom finishes, expansive entertaining spaces, and refined architectural details throughout. The primary suite is a true retreat, featuring dual private decks, custom closets, and a spa-inspired ensuite bath that rivals a luxury resort. Soaring ceilings, Pella windows, multiple Trex decks, and premium materials enhance the seamless indoor-outdoor lifestyle. Beyond its dramatic beauty, this estate offers rare peace of mind and modern convenience—including separate guest quarters, two gas fireplaces, a walk-out lower level to the garage, a brand-new septic system, new driveway, privacy gate, and professionally enhanced landscaping. Even more exceptional: no flood insurance required and a full-house generator—true rarities for waterfront living. Rated Diamond+++, this is more than a home—it’s a private coastal sanctuary where every day feels like a vacation, set within one of Long Island’s most exclusive and sought-after enclaves.
