Overview of 450 West 23rd Street

450 West 23rd Street is a five story, five unit co-op in Chelsea, occupying one of the Fitzroy Townhouses built in the mid 1850s. Its apartments retain the proportions and vertical organization of townhouse living, while the building operates as a small residential co-op.

The Fitzroy row was built on land once owned by Clement Clarke Moore and was known in the nineteenth century as “Millionaire’s Row.” The townhouses were converted to multifamily co-op apartments in the twentieth century and are now protected as part of a New York City Landmarks Preservation Commission historic district. Their Italianate façades and 23rd Street setting remain central to the building’s identity.

Apartment layouts include duplexes and triplexes, with high ceilings, hardwood floors, fireplaces, and interior staircases recurring across the homes. Private outdoor space is another defining feature of the apartment mix, taking the form of terraces, balconies, gardens, and roof decks; south facing exposures and views toward the Fitzroy Gardens also appear in several layouts.

The pet friendly co-op has completed capital improvements including a new roof, boiler, and hot water heaters. The High Line, Hudson River Park, Chelsea Piers, Chelsea Market, Little Island, Hudson Yards, and the West Chelsea gallery district are all close to the building, along with restaurants, shops, and cultural institutions in Chelsea and the Meatpacking District.

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.
