An extraordinary 3.2-acre opportunity in North Haven, just steps away from Sunset Beach, Long Beach, and even a short hop to Sag Harbor Village. The existing three-bedroom cottage offers immediate use while you design your Hamptons estate. Concept plans by Lang Architecture illustrate one possible 4,600± SF vision with pool and tennis - yet the property's generous acreage and zoning allow for a significantly larger build, offering the flexibility to maximize both scale and value. Recent nearby sales and new construction activity underscore the investment potential, with smaller parcels trading in the mid-$2M range and new homes in the area being developed in the $7-10M range. With its rare size, natural privacy, and proximity to Sag Harbor's beaches and marinas, this property stands out as one of the most compelling land-value offerings in North Haven.
