Set on 1.29 acres of lush, manicured grounds with a pool, hot tub, and century-old evergreens, this 16-room residence offers a rare blend of architectural history, elegance, and resort-style living. A true one-of-a-kind legacy property. Serving as a model home for the development, it initially functioned as a guest quarters for the club before being sold in 1904. Believed to be the work of Trowbridge & Livingston-the esteemed architects behind the original Ardsley Country Club, Newport Casino, B. Altman Building, & St. Regis Hotel. Inside, grand formal spaces unfold with soaring 10-foot ceilings, exquisite architectural details, and magnificent fireplaces. A wall of windows floods the expansive living room with natural light, showcasing fluted Ionic columns that exude timeless sophistication. The richly wood-paneled library, complete with a fireplace, invites intimate gatherings, while the stately formal dining room, also with a fireplace, opens to a private terrace-perfect for elegant entertaining. A striking solarium/family room features soaring cathedral ceilings and panoramic windows, creating a light-filled sanctuary. The renovated chef's kitchen preserves its historic charm with an original built-in hutch, a sunny breakfast area, and doors leading to the rear grounds. A graceful staircase ascends to the second level, revealing a serene bedroom suite with a fireplace and private bath, plus three additional bedrooms and a spacious deck with breathtaking golf course views. The primary suite enjoys a secluded wing overlooking the pool, boasting custom closets, an en-suite bath, and a fireplace. The third level offers three additional bedrooms, two connecting playrooms, a luxurious bath with a soaking tub, a cedar closet, and generous storage. Nestled in the heart of Dobbs Ferry's prestigious Ardsley Park, this home enjoys a prime location-just an eight-minute stroll to the village's charming restaurants and boutiques. For commuters, the 38-minute Metro-North ride to NYC provides effortless access to city life while preserving the tranquility of this historic estate.
