71 Old Mountain Road S Described in The Hook magazine as "Camelot on the Hudson, " this Hudson River mini-estate evokes the romance of a bygone era reimagined for modern living. Set on 1.37 lush acres, the five-bedroom main residence blends history and design-reclaimed wood floors, soaring ceilings, leaded-glass transoms, and sunlight filtering through tall windows that frame the river beyond. The gracious layout connects elegant entertaining spaces to a chef's kitchen designed for gatherings of family and friends, while the first-floor primary suite-with its fireplace, spa bath, and dressing room-offers a retreat of quiet luxury. Thoughtful updates including a new slate roof, copper flashing, and four Tesla Powerwalls pair sustainability with enduring quality. A detached writer's cottage with wood-burning stove invites creative work or peaceful retreat. Beyond this studio, in the third building on the estate, a separate guest suite with private deck and spa bath provides boutique-hotel comfort atop a heated four-car garage. Step outside onto any of the expansive decks to soak in the Hudson's ever-changing light by day or the magical shimmer of the Tappan Zee Bridge by night. Ride along the riverfront trails, dock your boat nearby, or explore the villages of Nyack and Piermont for dining, art, and live music. Just 15 minutes to Metro-North and 25 to the GW Bridge-riverfront living at its most refined: timeless, private, and effortlessly connected to the world beyond.
