17 East 84th Street is a boutique cooperative built in 1925 between Madison and Fifth Avenues. The pet-friendly building features a live-in superintendent and bike room.
17 East 84th Street is a 1925 pre-war cooperative in Carnegie Hill, designed by George F. Pelham and organized as an intimate nine story building with 24 apartments. Located between Fifth and Madison Avenues in the Metropolitan Museum of Art Historic District, it has just two apartments per floor, giving its classic layouts a relatively private scale.
The apartments reflect the building’s original residential planning, with recurring classic six and classic seven configurations, formal dining rooms, windowed kitchens, high ceilings, hardwood floors, and quiet courtyard or tree lined street exposures. Several homes have been adapted with washer and dryer installations, while larger layouts often retain staff rooms or studies, gallery entries, and separate bedroom wings. Wood burning fireplaces, stained glass, built in bookcases, and other pre-war details appear alongside renovated kitchens and bathrooms.
A distinctive penthouse residence is wrapped by landscaped terraces, with outdoor access extending from the living areas and skyline views above Fifth Avenue. The building also has a live-in superintendent, video intercom, basement laundry, storage, and a bike room; pets are permitted, and financing of up to 50 percent is allowed under the cooperative’s rules.
The address is on a tree lined block just off Fifth Avenue, with Central Park and the Metropolitan Museum of Art at the end of the block. Madison Avenue’s shops and restaurants are close by, while the surrounding historic district supplies the building’s immediate architectural setting.

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.
