A Rare Blend of Privacy, Luxury & Convenience in Cold Spring Harbor. Set on two private acres on a quiet cul-de-sac, this exceptional Colonial home offers a truly rare combination: complete privacy and seclusion just four minutes from Cold Spring Harbor train station. While many private estates are located farther from the station, it is unusual to find a property that offers this level of tranquility while remaining so conveniently close to the train, shopping, dining, major roadways, and Huntington Village. Completely rebuilt in 2008 and offering approximately 6,500 square feet, this sophisticated five-bedroom, five-and-a-half-bath residence combines generous living spaces with an extraordinary collection of amenities designed for both everyday living and grand-scale entertaining. The spectacular grounds are highlighted by an in-ground heated saltwater gunite swimming pool with waterfalls and LED lighting, all controlled by an app, a newly resurfaced championship tennis court with pickleball lines, using the same surface coating found at the US Open, and an expansive outdoor entertaining area. The resort-like setting also features a fully equipped outdoor kitchen with pizza oven, barbecue, sink, dishwasher, and refrigerator, a grand outdoor fireplace, and a spacious fire-pit alcove. Inside, the updated kitchen is appointed with Thermador ovens, a Sub-Zero refrigerator, and a new Miele dishwasher. Additional amenities include a private home theater with seating for 10, a wine cellar, a gym with virtual running routes for the treadmill, three fireplaces, and a luxurious primary bathroom with steam shower. Thoughtful architectural details include front and rear staircases, a second-floor laundry room, and a large second-floor bonus room. The home features central air conditioning and heating, each with four zones, along with a central vacuum system and 300-amp electrical service. The attached three-car garage provides ample space for vehicles, storage, and level 2 EV charging, while an Eagle Dock Beach (with dues) offers an additional opportunity for enjoying the area's waterfront lifestyle. Located in the highly regarded Cold Spring Harbor School District, the property is a private estate with resort-style amenities, remarkable entertaining spaces, and an exceptionally rare location—secluded in a quiet cul-de-sac, yet minutes from the train.
