434 West 23rd Street is a five story, five unit pre-war co-op in Chelsea, built in 1840 and identified with the historic Fitzroy Townhouses. Its townhouse scale is reflected in a mix of duplex and triplex layouts, with private outdoor space appearing as south facing terraces and roof decks.
The walk up building has an intercom and a pet friendly policy. A recent renovation brought a renewed lobby and digital entry system, while apartment layouts retain pre-war character through high ceilings, hardwood floors, and wood burning fireplaces. Many apartments also have in-unit washer dryers and generous storage.
The most distinctive homes extend across multiple levels, separating living areas from bedrooms and, in some cases, placing a private roof terrace above the residence. South facing outdoor spaces look over treetops, townhouse gardens, and the West Chelsea skyline, while upper level terraces include views toward the Hudson River and the Empire State Building.
The building is on a wide, historic West Chelsea block about half a block from the High Line. The surrounding area includes the West Chelsea galleries, Chelsea Market, the Whitney Museum, Hudson Yards, the Meatpacking District, and restaurants along Ninth and Tenth Avenues. The Fitzroy Townhouses stand on land once associated with Clement Clarke Moore.

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.
