This 7-story building from 1910 on the Upper East Side features unusual rounded corners and fire escapes with solid metal panels.

Currently, 3 apartments are for sale.
The Sussex, built in 1910 and converted to a cooperative in 1975, is a distinctive seven-story prewar building located at 55 East 65th Street. The 36-unit structure features unique architectural elements including a rounded west corner, pale orange brick façade above a two-story brownstone rusticated base, and distinctive fire escapes with solid metal panels painted to complement the exterior.
The building's architectural character is further enhanced by arched windows on the fifth and sixth floors, a five-step-up entrance stoop, and apartments featuring soaring 10-foot ceilings. Many units retain period details such as wood-burning fireplaces, while others have been modernized with contemporary finishes.
Residents benefit from building amenities including a live-in superintendent, private storage units, bicycle storage, and on-site laundry facilities. The pet-friendly cooperative is fully shareholder-owned, though pieds-à-terre are not permitted.
The location is particularly notable, situated on a tree-lined block between Park and Madison Avenues. The building sits directly across from Daniel, one of New York City's most celebrated restaurants, and holds historical significance being near the former residence of Franklin and Eleanor Roosevelt.
The Sussex enjoys proximity to Central Park, Madison Avenue's designer boutiques, exclusive private clubs, and the Plaza Office District. While the building lacks certain modern amenities like a doorman or roof deck, its prime Upper East Side location offers easy access to multiple transportation options including crosstown bus service and nearby subway stations.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
