Description

Rare and unparalleled opportunity to build your ultimate compound. Boasting 16.8 acres with 2000 feet of direct waterfront along the Long Island Sound in the exclusive, incorporated Village of Nissequogue. This sprawling legacy estate offers a rare combination of absolute privacy and endless coastal possibilities. Enjoy unparalleled, direct beach access via a staircase, allowing you to step off your estate and directly onto the sand to launch a kayak, paddleboard, or stroll the shoreline at sunset. Meandering trails, mature specimen trees, and stone paths complete this magnificent blank canvas. The expansive 11,000+ sq. ft. foundational footprint provides the perfect bones to recreate a world-class, 6-bedroom, 7-bathroom modern masterpiece, complete with structural footprints for both an all-season indoor pool and a sweeping outdoor pool oasis. A stone pathway leads you to the tennis court that is ready to be restored. Located in The Village of Nissequogue, Long Island’s best-kept luxury secret where unparalleled privacy meets pristine coastal living. This incorporated sanctuary offers a tranquil, estate-driven refuge just 50 miles outside Manhattan. Surrounded by StonyBrook Harbor, and the Long Island Sound. Residents also enjoy exclusive access to restricted shorelines like Short Beach and Long Beach, as well as the protected trails of the 150-acre David Weld Sanctuary.
