First time on the market in over 40 years, the Captain Walter Abraham Sammis House is a rare and distinguished offering in Cold Spring Harbor. Built in 1830 and impeccably restored by its current owners with meticulous attention to detail and expert craftsmanship, this remarkable residence offers a compelling blend of historic character, timeless elegance, and thoughtful modern refinement. Set on just shy of an acre with western water views overlooking Cold Spring Harbor, this sun-filled Colonial offers 5 bedrooms, each with water views, and 5.5 baths, all surrounded by beautifully landscaped gardens. Every principal room is filled with natural light, and many capture serene water views and beautiful sunsets. Early architectural details have been carefully preserved, including the classic three-bay side-hall plan, raised brick basement, Federal-style doorway with sidelights and decorative surrounds, Victorian-era front porch, Southern Yellow Pine wide-plank hardwood floors, clapboard siding, shutters, and exterior lanterns. Rich in character and designed for both gracious entertaining and everyday living, the home features a formal living room with porch access, a formal dining room with French doors opening to a bluestone patio, a den, a full finished walkout basement, and five wood-burning fireplaces. Custom cabinetry and beautifully updated kitchen and baths honor the home's original integrity while enhancing comfort and livability. Modern amenities include a chef's kitchen with built-in seating, recessed lighting, central air conditioning, and a 3-car garage. Ideally located just moments from Cold Spring Harbor Village, Huntington, the beach, and the train station, this exceptional historic residence offers a rare opportunity for those drawn to the beauty, craftsmanship, and legacy of a truly special home.
