Overview of 401 Eighth Avenue

401 Eighth Avenue, also known as The Roosevelt Arms, is a 1922 pre-war co-op one block west of Prospect Park. The seven story building contains 31 apartments and occupies an Eighth Avenue site between Fourth and Fifth Streets in Park Slope.

Many apartments pair generous room proportions and formal dining areas with multiple exposures. Renovated layouts often combine kitchen, living and dining spaces, while flexible rooms shift between enclosed sleeping space and expanded living areas. Apartment 3 has an unusual bi-level arrangement, with an internal stair connecting its lobby level rooms to a lower recreation space.

The building has a live-in superintendent, bike storage, basement laundry and individual storage cages. Pets are permitted, and several apartments have in-unit laundry. The address is zoned for PS 321.

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.
