Privately set on 1.5 beautifully landscaped acres along a quiet cul-de-sac, this six-bedroom Colonial offers approximately 4,900 square feet of above-grade living space in the Cold Spring Harbor School District. A long driveway, ample parking, expansive front lawn and mature landscaping create a private setting from the moment you arrive. Inside, a dramatic two-story foyer leads to a soaring living room filled with natural light. The spacious layout provides plenty of room for everyday living, working from home and hosting guests. Three of the upstairs bedrooms feature private en-suite bathrooms, including the expansive primary suite and two additional bedrooms, each with its own full bath. A flexible first-floor guest area with a full bathroom and separate side entrance provides additional privacy and versatility. The approximately 1,700-square-foot finished walk-out lower level adds even more usable space, with a theater/media room, game and recreation areas, a full bathroom, storage, and sliding doors leading outside. The backyard is the true centerpiece. An expansive Trex deck overlooks an in-ground pool with spa, koi pond and multi-sport court offering basketball, tennis and badminton options—all surrounded by greenery and privacy. Additional features include a two-car garage, central air conditioning, public water and sewer, and solar panels that are nearing full payoff. A rare combination of space, privacy and outdoor amenities in Cold Spring Harbor.
