31 Fort Hill Drive, Lloyd Harbor, NY, 11743 | $19,000,000

Welcome to 31 Fort Hill Drive, a landmark estate perched atop 10 private acres in the prestigious enclave of Lloyd Harbor. Set across two parcels with 1, 800 feet of private beachfront and a deep-water dock, this extraordinary compound offers uninterrupted, panoramic views of the Long Island Sound—widely regarded as among the finest vantage points on the North Shore. Steeped in natural beauty and rich American history, the estate sits on Fort Hill, a site of Revolutionary War significance where signal beacons once watched over the Sound. Today, the same elevated terrain offers a rare sense of seclusion, grandeur, and sweeping coastal vistas that change with every season and every tide. This custom brick residence is a masterwork of craftsmanship and scale, featuring 13 bedrooms, 10 full bathrooms, and four half baths. Elegant interior spaces include a sunlit solarium, a stately library, and an expansive, exquisitely detailed ballroom designed for unforgettable gatherings. Seven fireplaces, intricate millwork, and curated architectural details throughout add a sense of timeless refinement. A fully renovated gourmet kitchen anchors the home’s living spaces, offering high-end appliances, classic finishes, and effortless flow into formal and informal dining areas. Whether you’re hosting intimate family dinners or large-scale entertaining, the home rises to every occasion. Additional amenities include staff quarters, a 16-car garage with guest apartment suites above, a state of the art geothermal system, and flexible bonus rooms ideal for a private theater, wellness space, or art studio. Outdoors, a 3-acre curated garden with a greenhouse, invites peaceful strolls and moments of serenity amidst manicured plantings. From sunrise over the water to evenings under the stars, this is a home where every day is defined by natural splendor, privacy, and possibility. Just moments from Huntington Village and the train to NYC and located within the award-winning Cold Spring Harbor School District, 31 Fort Hill Drive is more than a home—it’s a legacy estate where history, beauty, and lifestyle converge.
