A sprawling 165-acre estate in New York’s Hudson Valley is on the market for $20 million, offering a rare blend of luxury and equestrian living. Owned by hotelier and polo enthusiast Philip Mactaggart, the property features a designer-built modern mansion, a regulation-size polo field, and serene views of the Taconic Mountains. Mactaggart bought the land for $3.5 million in 2014 and commissioned Resolution: 4 Architecture to construct the five-bedroom, eight-bath retreat, completed in 2019.

The 7,500-square-foot home unfolds across dual wings connected by a pivoting glass door and includes a soaring living and dining area anchored by a black steel fireplace, a library with a rolling ladder and hidden bar, and an all-white chef’s kitchen with a large butler’s pantry. A fireside media room, private office, mirrored gym, wine cellar, and rooftop deck with a bar and lounge enhance the living experience. The primary suite includes a meditation room, two dressing areas, and dual bathrooms.

Landscape architect Wagner Hodgson designed the grounds, which feature a vanishing-edge pool, spa, cabana with kitchen and lounge, croquet court, and an alfresco dining terrace. Equestrian amenities include two barns with 48 stalls, four pastures, fenced paddocks, and the polo field. Additional structures include two staff cottages and a three-car garage with a Belgian block motor court. Located near Amenia, Millbrook, and Wassaic, the property combines privacy with convenience in one of the Hudson Valley’s most scenic areas.
