870 Fifth Avenue is a distinguished 19 story cooperative built in 1949 by Simon Brothers and designed by William I. Hohauser. Located at the northeast corner of Fifth Avenue and East 68th Street directly across from Central Park, this beige brick building with a three story limestone base replaced the historic mansions of M.C. Inman and Robert L. Stuart (the latter extensively altered by McKim, Mead & White for financier William C. Whitney). The building's curved bays and angled corner windows create a distinctive soft edge, while its side street entrance on 68th Street provides an attractive and discreet entry point.
The cooperative houses 94 apartments (reduced from the original 106) across its 19 floors, with a thoughtful design that eliminates all rear apartments to ensure every unit enjoys either Fifth Avenue frontages overlooking Central Park or 68th Street exposures with southern light. Apartments range from one bedroom units to classic seven layouts and unique duplexes, many featuring direct Central Park views and spacious entertaining areas.
This full service white glove building offers comprehensive amenities including attended elevators, full time doorman and concierge, a fitness center, roof deck with Central Park views, bicycle storage, and central laundry facilities. The cooperative is notably flexible, permitting pied-à-terre ownership, pets, in-unit washer/dryers, and financing up to 50% of the purchase price. Located in the heart of the Upper East Side near Museum Mile, Madison Avenue shopping, and world class dining, the building maintains a 3% flip tax and represents one of the more accessible luxury cooperatives on this prestigious stretch of Fifth Avenue.

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.
