Public School 9 Annex at 279 Sterling Place is a remarkable architectural conversion that transforms Brooklyn's educational history into distinctive residential living. Designed by James W. Naughton in 1895 in the Renaissance Revival style, this landmarked building is listed on the National Register of Historic Places and stands as one of Prospect Heights' most striking structures. The terra cotta Romanesque Revival building was converted by local artists into a residential co-op in 1989, creating 22 unique units across four floors with elevator access.
The building's former classroom spaces have been transformed into dramatic loft style apartments featuring soaring 13 to 14 foot ceilings and oversized 10 foot windows that flood the spaces with natural light. Many units showcase original architectural details including exposed brick archways, decorative moldings, and maple hardwood floors. The apartments range from studio lofts to sprawling three bedroom homes, with several featuring duplex layouts, loft sleeping areas, and in-unit washers and dryers. Notable amenities in select units include wood burning fireplaces, private terraces, skylights, and extensive built in storage accessed via pulldown attic staircases.
The building offers a full service garage with gated parking, a manicured communal garden courtyard, and video intercom system. Located at the corner of Sterling Place and Vanderbilt Avenue, residents enjoy prime access to Prospect Park, Brooklyn Museum, Brooklyn Botanic Garden, and Grand Army Plaza's Saturday farmers market. The pet friendly co-op provides convenient transportation via the 2/3 trains at Grand Army Plaza and B/Q trains at 7th Avenue, placing residents in the heart of one of Brooklyn's most vibrant cultural neighborhoods with abundant dining and shopping along Vanderbilt and Washington Avenues.

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.
