This elegant five-bedroom colonial is set on a flat, private two-acre property with water views from the front of the home. Offering nearly 4,000 square feet of gracious living space, the residence blends classic colonial architecture with an exceptional North Shore lifestyle. The main level features a beautiful eat-in kitchen, ideal for everyday living and entertaining, along with a formal living room, spacious family room, and a large formal dining room perfectly suited for holiday gatherings and dinner parties. A first-floor bedroom with access to a full bath provides flexibility for guests or extended family and may also be reimagined as a home office or playroom. The second level offers a primary suite with multiple configuration options for the next owner. Currently arranged with an additional room and two separate walk-in closets—previously used for a home business—this space, combined with the bedroom, walk-in closet, and large bath with cathedral ceilings, presents the opportunity to create an approximately 750-square-foot private retreat. Three additional generously sized bedrooms and a well-appointed updated bath are filled with natural light. The home is enhanced by owned solar panels, delivering significant energy savings of approximately $10,000 annually. As a member of the Quail Hill Beach Association, residents enjoy deeded beach rights, breathtaking western sunsets, and the rare opportunity to keep a boat directly off the private beach. Village amenities include a private police force, a resident-only beach with summer camp, and close proximity to Caumsett State Historic Park Preserve and Target Rock National Wildlife Refuge. Located within the Cold Spring Harbor School District and convenient to the Huntington area’s shops, dining, and cultural amenities, this is North Shore living at its finest.
