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.
