The Residence at River House
River House, for the first time in the 82-year history of this iconic building, is offering for sale The Residence at River House. The Residence is being offered in its existing condition, enabling the purchaser to create what will truly be one of the grandest urban residences in the world. It will be the largest single family home in New York City – in the proposed renovation plan designed by Tony Ingrao it would comprise over 62,000 square feet on five levels. It is the most important private residential property in New York City history to come to market.

Designed by the classical American architect, William Bottomley, River House epitomized the height of luxurious living when the building opened in 1931. The Residence overlooking the East River will reflect the same qualities updated for 21st century living. Offering a residence at the base of a significant building is very much in keeping with other stately New York cooperative buildings such as the maisonettes at the base of the Carpenter and Candela-designed cooperatives of Fifth and Park Avenues.

A proposed renovation designed by renowned interior designer Tony Ingrao capitalizes on the palatial scale of this incredible home. Residents and guests will enter through a private entrance from the East 52nd Street cul-de-sac into the 8,400 square foot Entrance/Living Level. The major public rooms feature 20’ ceilings and expansive light-filled spaces. The 27,500 square foot Garden/Leisure Level includes an 82’ swimming pool, tennis court, screening room, wine cellar, full spa and gaming room. The 15,000 square foot Bedroom Level features a 27 × 61′ Master Suite, and also includes his and her baths, dressing rooms and closets. The Staff Level offers nearly 6,000 square feet of work areas, bedrooms and lounges.The Residence will maintain self-contained mechanical systems.

Given the unique qualities of the Residence, the River House cooperative corporation has enacted rules to govern its disposition, renovation and utilization.

Floor plans available upon request.
