Overview of The Adelaide at 635 Park Avenue

635 Park Avenue remains a sought-after address, combining historical significance, elegant design, and a desirable location for discerning buyers. Throughout its history, 635 Park Avenue has housed notable residents, including horticulturist and philanthropist Harriet Barnes Pratt, Walter Hoving of Tiffany & Co., and Lord Conrad Black, a former publishing magnate.

The elegant  full-service building was designed by renowned architect J.E.R. Carpenter, erected in 1912, and converted to a cooperative in 1946. The distinguished 13-story residence features just 16 apartments, offering an exclusive living experience in a prime Park Avenue location.

The building's light-brown brick façade, styled in Italian Renaissance palazzo, exudes understated grandeur. A canopied entrance, adorned with sidewalk landscaping, leads into a welcoming lobby. Architectural highlights include lunette decorative panels above the second-floor windows, a broad band course above the third floor, and a detailed cornice with arches and multi-paned windows.

635 Park Avenue provides a range of amenities, including a full-time doorman, elevator operator, live-in superintendent, and storage options. The building permits a maximum of 50% financing, enhancing accessibility for prospective buyers.

Apartments within the building are known for their exceptional layouts, often featuring a circular foyer, expansive living rooms measuring up to 30 feet long, and formal dining rooms that enhance the entertaining experience. As noted by Paul Goldberger in The New York Times, the floor plans are skillfully divided into public, private, and service areas, providing a harmonious flow and optimal functionality.

The building replaced the Adelaide, an earlier structure designed by Henry J. Hardenbergh, famed for his work on the Dakota and the Plaza Hotel.

Situated at the corner of 66th Street, the building is conveniently located near the prestigious 7th Regiment Armory and is surrounded by a variety of religious institutions, boutique shops, and fine dining. Excellent public transportation options, including cross-town bus services and nearby subway stations, ensure effortless access to Midtown and beyond.

Carter’s Review

"This understated but grand apartment building at 635 Park Avenue on the southeast corner at 66th Street was erected in 1912 and converted to a cooperative in 1946.

It was designed by J. E. R. Carpenter, the leading architect of luxury apartment buildings in the city of his generation, for Spencer Fullerton Weaver, who was also the developer of 630 and 640 Park 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.
