Overview of 7 East 78th Street

7 East 78th Street, originally known as The Percival Kuhne House, is a distinguished Beaux Arts mansion designed by the architectural firm Hoppin & Koen. Built as a 25-foot-wide residence, the building was converted into a co-op in the 1950s, comprising eight unique units. The property is ideally situated just steps from Fifth Avenue and Central Park, making it a prime location for those seeking the vibrancy of the Upper East Side.

The featured unit, a duplex with nearly 1500 square feet, offers a spacious layout with 10-foot ceilings and original prewar moldings. The main level includes a large living area, a turret dining space, and a renovated kitchen equipped with Sub-Zero appliances. The primary bedroom is conveniently located on this floor, accompanied by an oversized bathroom adorned with marble tiles. A spiral staircase leads to the lower level, which features a recreation room, a full bathroom, and access to a private outdoor space, ideal for entertaining or gardening.

The building's amenities include a beautifully designed entrance with a double door entry and elevator access. Residents enjoy the flexibility of a pet-friendly policy, while subletting is not permitted. The co-op allows for pied-à-terre arrangements and trust purchases, enhancing its appeal to a diverse range of buyers. With its proximity to cultural landmarks, high-end shopping, and fine dining, 7 East 78th Street represents a unique opportunity to own a piece of New York City's architectural 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.
