River House is one of Manhattan’s finest and most discreet addresses. Designed by William L. Bottomly in 1931, this architecturally exquisite art deco building is notable for its elegantly gated entrance court and its inspired, light-filled lobby, which opens onto tiered gardens with views of the East River and beyond. Impeccable service includes two full-time doormen and a concierge, as well as a top resident manager, and private storage. Further, as a shareholder at River House and with the River House Board as one’s sponsor, it is possible to join The River Club, located at the base of River House along the East River and with its own entrance on East 52nd Street (as well as a convenient internal door from the River House lobby). The River Club is an exclusive and storied social and sporting club that offers tennis, squash, a swimming pool and golf simulator, dining (and in-apartment catering and delivery to River House residents), guest rooms, and an array of social programs for adults and children. With sparkling and glorious views of the East River, grand proportions, and a design that lends itself perfectly to an extremely elegant lifestyle, this residence offers extraordinary amenities as access to membership at The River Club, this immensely grand duplex within one of New York greatest prewar buildings is truly an oasis from the brisk pace of the city.
