Overview of 321 West 78th Street

321 West 78th Street is a 1924 pre-war co-op on the Upper West Side, less than half a block from Riverside Park. The 9 story building contains 54 apartments, with classic five, six, and seven room plans forming much of its housing stock.

Many apartments preserve high beamed ceilings, hardwood or herringbone floors, broad entry foyers, formal dining rooms, and windowed kitchens and baths. Several corner and wing spanning layouts have three exposures, while formal dining rooms in multiple plans can be reconfigured as an additional bedroom. Classic six room homes may retain an original staff room or adapt it as an office, and many renovated homes have in-unit laundry.

The building has a 24 hour doorman, live-in superintendent, package room, central laundry room, resident storage, and bicycle storage. It is pet friendly and permits pied-à-terre ownership. Riverside Park’s promenade and cycling paths are just west, while the 1 train stops at 79th Street and Broadway, near Zabar’s and the commercial corridor along Broadway.

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.
