River House is an iconic 26-story prewar cooperative in Manhattan completed in 1931 and designed by Bottomley, Wagner & White. The complex reads as a center tower flanked by two 15-story wings and contains a small number of large, traditionally proportioned residences—three- to six-bedroom layouts predominate—many with private elevator landings, high ceilings, formal galleries, extensive built-ins, and fireplaces. Interiors preserve classic prewar details (hardwood floors, plaster moldings, mahogany millwork) while many apartments have been upgraded with modern kitchens, multiple baths, laundry rooms and extensive storage. Communal life centers on meticulously planted grounds: a gated cobblestone motor court, manicured gardens, a lawn with children's play area, terraces and roof deck spaces. On-site services are full white-glove: 24-hour doormen and concierge, resident manager and a substantial in-house staff team. Building amenities extend to organized social and sports facilities via the River Club—located within the building—with pool, squash and tennis courts, fitness center, dining room, ballroom, guest rooms and library. Practical features include multiple passenger and service elevators, ample storage, and pet and pied-a-terre policies. Located on a quiet cul-de-sac along the East River in Sutton Place, River House offers a tranquil, service-oriented residential setting with long river and city vistas.
