Set atop 5.37 lush and private acres with water views of Oyster Bay Harbor, this magnificent three-story Colonial offers more than 7,000 square feet of historic elegance, gracious living, and exceptional entertaining spaces. Built in 1888, the six-bedroom, 7 -bath (5,2) residence embodies the classic grandeur and architectural character of a bygone era, beautifully complemented by an extraordinary floor plan. From the moment you enter, the home’s remarkable craftsmanship is on full display. High ceilings, exquisite custom woodwork, graciously scaled rooms, and historic architectural detailing create an atmosphe

The home’s covered porches span both the first and second floors, providing idyllic spaces to relax, entertain, and take in the surrounding landscape and harbor and pond views. The property’s elevated setting and mature grounds offer a rare combination of privacy, natural beauty, and proximity to the water. Exceptional outbuildings further distinguish this remarkable estate. A detached four-car garage features guest quarters above, while a separate detached two-car garage provides additional parking and storage.
