About This Home
As of April 2026Welcome to Mountain Brook Estate, an ultra-private, luxurious mountaintop retreat encompassing 26+ acres on one of the highest elevations in the Hudson Valley. An hour from New York City and minutes from West Point, this nearly 8,000 square foot contemporary estate has been meticulously renovated to showcase commanding views of the Hudson River, Storm King Mountain, and the surrounding Catskill and Shawangunk ranges. Blending modern design with timeless elegance, the open-concept residence offers a generous kitchen with two islands, adjacent dining area, 3 great rooms, 4 bedrooms, with a collection of (5) versatile bonus rooms and private offices that can be tailored for additional sleeping quarters, creative studios, or wellness spaces. The open-concept layout is framed by soaring ceilings and walls of glass, allowing natural light and panoramic vistas to flood every corner. Multiple fireplaces and thoughtfully designed living spaces create the perfect balance between comfort and sophistication. Every element of this estate invites rest and restoration. Start your mornings in the carriage house yoga studio, take a swim in the indoor lap pool, or relax in the brand new infrared sauna. Private manicured walking trails wind through the grounds, connecting curated viewing platforms, peaceful gazebos, and secluded seating areas, designed to immerse you in the landscape while offering moments of quiet reflection. Expansive wraparound decks, two outdoor fire pits, organic garden, a rooftop tower, and a broad great lawn provide an ideal setting for elevated entertaining or serene relaxation, all surrounded by nature at its most majestic. A 10-acre meadow on the property offers unlimited development potential.
Additional features include an 1,100 sq ft guesthouse or studio, a radiant-heated Finnish soapstone fireplace, an oversized 3-car garage, and a whole-house generator to ensure complete peace of mind. Whether you're envisioning a world-class weekend escape, a legacy compound, or an exceptional investment property, Mountain Brook Estate delivers unmatched luxury, privacy, and scale, just a short drive from the city, yet truly a world apart.
