639 West End Avenue is a distinguished Neo-Renaissance-style cooperative located in the Riverside-West End Avenue Historic District. Built in 1927 and converted to a co-op in 1976, the 15-story, yellow-brick building features 65 units, with just three apartments per floor, offering an intimate living experience.
Architectural details include a limestone base, decorative rope quoins, arched windows, and a scalloped cornice. A canopied entrance and sidewalk landscaping enhance the building’s stately presence. Positioned across from the low-rise Greek Orthodox Church of America, residenes in the building enjoy abundant natural light and open views.
Amenities include a full-time doorman, 24-hour elevator attendants, a live-in superintendent, bicycle storage, and a central laundry room. Private storage units are available for rent. Mail and packages are delivered directly to residents’ doors for added convenience.
The building permits pets and allows up to 75% financing. While there is no health club, roof deck, or garage, the prime Upper West Side location provides easy access to Riverside and Central Parks, as well as top-rated restaurants, shops, and cultural destinations.
Residents benefit from nearby public transportation, including the 1/2/3 and B/C subway lines, multiple bus routes, and CitiBike stations. Trinity School, one of the city's most prestigious private schools, is just a few blocks away.

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.
