About this House
Welcome to Terre Haute
The property was originally part of a 74-acre tract held by the Hewlett family for more than two centuries. When the land was finally opened for development, the wife of the builder personally followed the bulldozer onto the property and selected this exceptional parcel—the first parcel to be sold from the historic Hewlett tract.
That instinctive choice remains evident today.
The custom-built residence was deliberately positioned to embrace the property’s extraordinary natural topography. Its principal living spaces—the Living Room, Dining Room, Kitchen, and Porch—face the dramatic northern slope, allowing the architecture to open naturally toward the land while creating a remarkable sense of space and seclusion.
The bedrooms are oriented toward the steep western boundary, where the natural grade provides an uncommon degree of privacy from neighboring properties. Rather than relying on walls or landscaping alone, the home is protected by the land itself—a remarkable gift bestowed by the glacier millions of years ago.
The expansive lawn stretches gracefully across the property, offering an exceptional setting for outdoor entertaining, recreation, or an informal game of touch football. Generous off-street parking further enhances the property’s convenience.
Perched atop a commanding 2.55-acre hilltop at the end of a quiet cul-de-sac, this exceptional 3,300-square-foot residence offers 4/5 bedrooms, 3 full baths, and extraordinary 360-degree privacy, creating a true estate setting on one of Cold Spring Harbor’s most desirable multi-acre properties.
Enjoy seasonal harbor views through the trees, with the opportunity to add a second story and capture year-round panoramic harbor vistas. Combining luxury, privacy, and remarkable potential, this is a rare offering at an exceptional value.
A gracious, tree-lined entrance drive welcomes you to the beautifully positioned home, where a sun-drenched living room features hardwood floors and oversized windows framing tranquil, park-like surroundings. The main level includes a spacious primary en-suite, a guest bedroom, and a versatile office or den that can easily be converted into a fifth bedroom. Recessed LED lighting throughout.
The generous eat-in kitchen opens to a covered porch, providing the perfect setting for effortless indoor-outdoor living and entertaining.
The ground garden level features two additional bedrooms, a luxurious marble bath, and an expansive recreation and entertainment room—ideal for hosting and entertaining.
Ideally located just five minutes from the Cold Spring Harbor LIRR station, with easy access to Jericho Turnpike and the Long Island Expressway, the property is also moments from Eagle Dock Beach (dues required), scenic state park hiking trails, and is situated within the Cold Spring Harbor Central School District.
A rare opportunity to own an exceptional private estate offering the perfect blend of natural beauty, convenience, and unlimited potential.
Incredible Scenic Vistas with Complete Seclusion a Nature's Lovers Paradise.

NAGreatSchools RatingParent Rating AverageMy son completed his kindergarten at Goosehill, and we are very happy to see how much he had learned and grown in a year. He is now able to read short fiction and non-fiction books on his own, and he begs us to take him to the Cold Spring Harbor Library every week. All parents in his class were very involved, from volunteering in school activities to after-school social events & play dates. Very close knit. Class sizes are small (less than 20) so each kid gets plenty of attention and teachers really tailor their teaching according to my son's specific interests and abilities. This school convinces us that we made the right decision to relocate to Lloyd Harbor. Highly recommended if you are searching for the best school district for your own kids.Parent Review12y ago
