Overview of 507 West 111th Street

The Blennerhasset at 507 West 111th Street is a six story, 32 unit pre-war co-op completed in 1915 in the Morningside Heights Historic District. Its tree lined block runs between Broadway and Amsterdam Avenue, with the Cathedral of St. John the Divine and its gardens one block east.

Layouts retain the flexibility associated with larger pre-war rooms: one bedroom homes may use a formal dining room as a second bedroom, while several two bedroom plans can be arranged with three. High ceilings, hardwood floors, original woodwork, pocket doors, windowed kitchens and bathrooms, and multiple exposures recur in the apartments. Some homes overlook the courtyard, and Unit 21 has a Juliet balcony facing its trees.

The building has central laundry, bicycle and private storage, a play and community room, a library, video intercom service, a part time superintendent, and a landscaped courtyard with a basketball hoop. Recent work included Local Law 11 façade requirements and a new roof, with an assessment scheduled through May 31, 2027. The Julia Gabriel People's Garden is at the corner, the Hungarian Pastry Shop is near Amsterdam Avenue, and Columbia University, Riverside Park, and Morningside Park are close by.

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.
