This handsome, 16-story, apartment building on the northeast corner of Ninth Avenue at 365 West 20th Street is known as Chelsea Court Tower.
It was built in 1928 and was designed by C. P. H. Gilbert, who built many major Manhattan mansions including the Jewish Museum on Fifth Avenue and 92nd Street, the Convent of the Sacred Heart School on Fifth Avenue and 91st Street, Cartier’s on Fifth Avenue and 52nd Street, and the Polish Consulate General on Madison Avenue at 37th Street.
This building has 74 co-operative apartments. Amenities include a part-time doorman (4 p.m.-midnight), live-in superintendent, porter, shared landscaped roof deck, central laundry room, on-site storage and bicycle room. The building is conveniently located close to the High Line, Chelsea Market, Hudson River Park, Ninth Avenue restaurants and shopping, and several forms of transportation. Pied-a-terre, gifting and co-purchasing permitted on a case-by-case basis.

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.
