The Lonsdale is a luxury prewar cooperative at 565 Park Avenue developed by Bing and Bing and designed by acclaimed architect Robert T. Lyons in 1912. The 14-story beige brick building was converted to co-ops in 1962, and there are only two units per floor. All apartments boast grand proportions, high ceilings, and excellent natural light.
The full-service building's amenities and staff include a 24-hour doorman, live-in superintendent, live-in resident manager, private basement storage, and a bike room. Central Park, Madison Avenue shopping, Michelin-starred restaurants, and top museums are a short walk away. Pets and up to 50% financing are permitted.

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.
