100 West 81st Street

This small but prominent 7-story building on Columbus Avenue was created by converting four flats and a commercial building from the 1880s into 16 co-operative apartments between 1978 and 1982. The building is distinguished by its dark gray façades and curved balconies, and is located across from the American Museum of Natural History in the Upper West Side/Central Park West Historic District.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

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.
