Overview of 425 East 78th Street

425 East 78th Street is a 1910 Lenox Hill co-op created by merging two brownstones. The six story building contains 34 apartments, with multiple duplex and loft style layouts in the mix.

Sunken living rooms, high ceilings, exposed brick and hardwood floors recur, while several homes face the tiered rear garden. Two residences have wood burning fireplaces. Apartment 1C is organized as a duplex beneath a cathedral ceiling, with sleeping space on the upper level and three separate entrances.

The landscaped rear garden is joined by a laundry room, live-in superintendent, virtual doorman and security cameras. Maintenance covers heat, water and gas. Pets up to 25 pounds and pied-à-terre ownership are permitted, while joint purchases, gifts, parental purchases and subletting are subject to board review.

The building is on East 78th Street between First and York avenues. John Jay Park is one block south at East 77th Street, and Carl Schurz Park begins at East 84th Street along East End Avenue. The Q train stops at 72nd Street and Second Avenue; the 86th Street Q station has an entrance at 83rd Street and Second Avenue.

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.
