The Chelsea Warren is a 1938 Art Deco co-op at 155 West 20th Street, designed by architect Horace Ginsberg and converted to cooperative ownership in 1988. The six story building contains 61 residences, and its period character begins in the entrance and lobby, where geometric terrazzo flooring and recessed Deco lighting remain defining elements.
The pre-war layouts are marked by gracious entry foyers, sunken living rooms, windowed kitchens and baths, hardwood floors, and substantial closet space. South and west exposures recur in the corner apartments, while several alcove studios have layouts flexible enough to create separate sleeping rooms. Many renovated homes have added in-unit laundry without removing the building’s original spatial features.
A live-in superintendent and full time porters staff the building, which also has a laundry room, bike room, intercom, and private storage. The lobby and hallways were renovated in 2020, followed by exterior restoration in 2021, roof and sidewalk work in 2022, and new landscaping, tree pits, and guardrails in 2023. Pets are allowed.
The building occupies a tree lined block directly across West 20th Street from Chelsea Green, between Sixth and Seventh avenues. The surrounding section of Chelsea is close to the Flatiron District, Union Square, Madison Square Park, the High Line, and the galleries and restaurants farther west in the neighborhood.

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.
