This Cornwall-on-Hudson, NY property transformed a steep Hudson River hillside into a dramatic outdoor living space. A custom infinity-edge gunite pool was engineered to visually merge with the river and views of Bannerman Island. Extensive retaining walls, deep foundations, drainage, and site stabilization made the previously “unbuildable” slope possible. An elevated patio with an outdoor kitchen and bar seating maximizes the panoramic views, while layered landscaping, irrigation, and lighting complete this one-of-a-kind custom pool and backyard retreat.
