650 Park Avenue, an elegant 21-story white glazed brick cooperative building, was erected in 1963 and designed by Kokkins & Lyras. The building stands on the former site of the historic Sulgrave Hotel at the southwest corner of Park Avenue and 67th Street, directly across from the landmark 7th Regiment Armory.
The building was specifically engineered with exceptional soundproofing features, including cork-lined concrete floor slabs, mineral wool-filled walls, and specialized kitchen floor construction. These architectural details demonstrate the thoughtful consideration given to resident comfort in the original design.
Comprising 98 cooperative apartments, the building is known for its generous floor plans and well-proportioned rooms. Many units feature terraces, and the building maintains a standard of one bathroom for every bedroom plus a powder room in each apartment. Several apartments offer impressive layouts with formal dining rooms, libraries, and staff quarters.
As a full-service cooperative, the building provides 24-hour doorman service, concierge, live-in resident manager, fitness center, storage facilities, and a rooftop terrace. An on-site parking garage offers reduced rates for shareholders, and all utilities are included in the monthly maintenance.
The building permits pets and pied-à-terres with board approval and allows up to 50% financing. A 2% flip tax is paid by purchasers. The location offers convenient access to Central Park, cultural institutions, high-end shopping, and public transportation.
The property's prestigious Upper East Side address, combined with its thoughtful design elements and comprehensive service offerings, has established it as one of Park Avenue's notable residential buildings.

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.
