Overview of 348 12th Street

348 12th Street is a 1920 pre war, four story co op with eight apartments at the corner of 12th Street and Sixth Avenue in Park Slope. The building includes a structurally unusual residence organized around a ground floor layout with a private entrance, 15 foot cathedral ceilings, and a lofted upper room that connects to the main living areas.

Apartment layouts include three bedroom homes, with high ceilings, wood burning fireplaces, hardwood floors, and in-unit laundry recurring among the residences. Shared amenities include basement storage and a patio, while the building has recently redone its roof and well maintained mechanical systems.

The co op is self managed and has no underlying mortgage. Cats are permitted, and dogs are subject to board approval. The building's small scale and pre war construction are paired with renovated apartment interiors, including updated kitchens and baths in the homes represented here.

Prospect Park is about three blocks away, and the building sits one block from both Fifth and Seventh avenues, the neighborhood's main restaurant and shopping corridors. Nearby establishments include Bar Toto, Piccoli Trattoria, Cafe Grumpy, Union Market, and Brookvin, with additional cafes, boutiques, and services along the surrounding Park Slope blocks.

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.
