Overview of 1815 Foster Avenue

1815 Foster Avenue is a six story, 54 unit Art Deco co-op built in 1931 in Flatbush. Its defining feature is its adaptable pre-war planning: generous one bedroom layouts have been converted into two bedroom homes, while foyers, raised dining areas and separate flex rooms provide space for offices or dens.

Many apartments retain high ceilings, parquet or hardwood floors, arched openings and moldings, with bedrooms often separated from the main living areas by a central hall. The building has a live-in superintendent, a part time evening doorman, basement laundry, a fitness room, community and play space, bike storage, resident storage and a common courtyard. Cats are permitted, but dogs are not.

Newkirk Plaza, served by the B and Q trains, is about two blocks away, with shops and restaurants extending along Newkirk and Foster avenues. Cortelyou Road’s year round farmers market is also close by, and the surrounding Ditmas Park streets are lined with mature trees and detached Victorian houses.

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.
