Tucked away at the end of a quiet cul-de-sac, this private 4-bedroom, 3-bath home sits on a beautifully landscaped, park-like acre, offering peace, privacy, and effortless living all on one level. A long, 200-foot driveway provides a grand and private approach to the home. Inside, an airy open floor plan is anchored by a dramatic Grand Room with soaring 18-foot ceilings and a striking stone fireplace. A full wall of glass sliders floods the space with natural light and opens to a sprawling deck that wraps around a heated in-ground pool and hot tub-perfect for seamless indoor-outdoor entertaining. The kitchen is thoughtfully designed with a sleek KOBE hood, Samsung appliances, and generous counter space, ideal for both everyday living and hosting. The central air system is controlled by an intuitive NEST thermostat for year-round comfort. Each of the four bedrooms enjoys double exposure, bringing in abundant natural light and views of the surrounding greenery. The primary suite features a spacious bathroom with a soaking tub, separate shower, and double-sink vanity. Adding to the property's appeal is a legal, two-story accessory studio structure offering remarkable flexibility. This bright and spacious outbuilding includes two and a half baths, recreational space on the first floor, a sitting room on the second level, and additional attic storage-or use as a great pool house. Additional highlights include an outdoor shower for post-beach refreshment, a two-car garage, and city water service for ease of maintenance. The pool is both heated and childproofed, making the outdoor space as practical as it is inviting. Ideally located just three-quarters of a mile from the Westhampton train station, a half mile from the Westhampton Tennis Club, and under two miles to the vibrant village center, this property blends quiet privacy with convenience-an ideal Hamptons retreat or full-time residence.
