About This Property

Set majestically on nearly three gated acres in Armonk's coveted Wrights Mill Estates, this extraordinary hand-cut stone manor with over 12,000 sq ft of classic architecture, artisan craftsmanship, and resort-caliber living. A breathtaking foyer leads to the two-story great room with an impressive window wall and fireplace.  A richly paneled study and sunlit conservatory offer space for dual home offices. A family room, dining room, chef's kitchen with pantry and breakfast room, complete the main level. The upper level offers a grand primary suite, a luxurious retreat featuring a fireplace, dual spa baths, separate dressing rooms, and a third-floor private wellness space with sauna. Additionally, upstairs, four ensuite bedrooms, laundry room and den are joined by a dramatic enclosed bridge leading to a private guest wing. The lower level rivals a private club with lounge, wet bar, wine cellar, theater, gym, hot yoga studio, bedroom, bath and second laundry. Outdoor amenities are designed for both relaxation and entertaining, featuring a beautifully integrated pool, an independent spa, expansive terraces and patios and a built-in outdoor grill. The flat, beautifully manicured grounds are complemented by an elegant courtyard with eight garage bays providing generous space for prized automobiles and collections alike. Combining timeless-inspired grandeur with modern luxury, this remarkable estate presents a rare opportunity to enjoy a private country-club lifestyle just minutes from downtown Armonk and Greenwich, with convenient access to New York City. A truly exceptional opportunity for the most discerning buyer.
