Overview of 1815 Foster Avenue

1815 Foster Avenue is a well-maintained six-story Art Deco co-op building located in the heart of Ditmas Park, Brooklyn. Constructed in 1931, the building features a classic brick façade and elegant detailing that reflects its historic charm. With 54 units, it offers a variety of spacious apartments, many of which boast high ceilings, hardwood floors, and abundant natural light. Notable for its generous layouts, some units can be easily converted to two or even three bedrooms, making them ideal for families or those seeking extra space for a home office.

Residents enjoy a suite of amenities including a live-in super, elevator, central laundry, bike room, community/playroom, small gym, and a common courtyard. The building is pet-friendly, allowing cats but not dogs, and features a monthly assessment for ongoing maintenance. Its prime location provides easy access to local shops and eateries along Newkirk Avenue and Cortelyou Road, as well as convenient transit options with nearby B and Q trains, ensuring quick access to Manhattan and other parts of Brooklyn.

The surrounding neighborhood is characterized by tree-lined streets and Victorian homes, offering a blend of charm and urban convenience. Noteworthy local establishments include Coffee Mob, Milk & Honey, and the year-round farmers' market on Cortelyou Road. This combination of historic architecture, modern amenities, and a vibrant community makes 1815 Foster Avenue a desirable place to call home.

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.
