Nestled on over 4 magnificent acres off a quiet cul-de-sac, this classic young Georgian manor epitomizes "Gold Coast" luxury and gracious living. Reminiscent of an English nobleman's country estate, the approximately 7,000 square-foot manse, with 5 bedrooms and 5.5 baths, is approached by a tree-lined drive and spacious front courtyard. A second drive leads to an equally spacious side courtyard serving the attached 3-car garage. Expansive, level lawns, rimmed with towering trees, create a sense of endless splendor. An expansive bluestone terrace at the rear of the home includes an outdoor kitchen and bar with a seating area. A brick walkway leads to a Roman-style inground Gunite pool with a spa, waterfall, and brick surround, offering an ideal venue for summer enjoyment and entertaining. The home's interior boasts exquisite architectural details and superb craftsmanship. The 2-story entrance foyer features a floating bridal staircase, wainscoting, and high arched doorways. The sunken living room has a high tray ceiling, leading to a welcoming sunroom with French doors to the terrace. The eat-in kitchen includes marble floors, granite-topped custom cabinetry, and high-end appliances. The second floor features two master suites with opulent marble baths. Located in Old Westbury, this stunning home offers convenience to golf and equestrian facilities, superb shopping and dining, beaches, boating, and a half-hour commute to New York City.
