Overview of 523 8th Street

523 8th Street is a four story pre-war co-op completed in 1920 on a landmarked, tree lined block between Prospect Park and 8th Avenue. The limestone building has a barrel front and nine apartments, with original details such as parquet floors, ornamental moldings, archways, built in armoires, and tin ceilings. The block’s Eighth Street Block Association received the Brooklyn Botanic Garden’s Greenest Block Award in 2012.

The apartments have flexible layouts, including multi room homes with den, nursery, or office spaces that can be reconfigured into additional bedrooms. Listings also show a range extending from studios to larger top floor apartments with open sky or treetop views, along with recurring pre-war features such as high ceilings, hardwood floors, and strong natural light. Several homes have renovated windowed kitchens and bathrooms, while exposures include southern, eastern, western, and southwest orientations.

Building amenities include a central laundry room, private storage, and locked bicycle storage in the basement; some apartments have deeded storage or individual storage cages. The co-op is pet friendly. Prospect Park is one block away, with Harmony and Third Street playgrounds nearby, and the weekend Greenmarket operates at 15th Street and Prospect Park West. The F and G trains stop at 7th Avenue, while 7th Avenue’s restaurants, cafes, bars, and shops are one block from the building.

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.
