Overview of 333 West 21st Street

333 West 21st Street is a charming pre-war co-op building that was constructed in 1900 and converted to cooperative ownership in 1988. Located on a quiet tree lined block in Chelsea between Eighth and Ninth Avenues, this boutique building contains 54 units spread across 5 stories and is part of a three building cooperative complex. The elevator equipped building maintains the character of its era while offering modern conveniences.

The apartments consistently feature classic pre-war details including exposed brick walls, decorative fireplaces, high ceilings, and original hardwood floors throughout. Many units have been thoughtfully renovated with updated kitchens featuring stainless steel appliances, subway tile backsplashes, and custom cabinetry. South facing apartments offer excellent natural light, while rear facing units provide quiet living spaces overlooking courtyards and neighboring townhouses.

Building amenities include a common roof deck with 360 degree Manhattan views and Empire State Building sightlines, on-site laundry facilities in the basement, bike storage, and storage lockers available for a monthly fee. The building employs a live-in superintendent and features video intercom entry. Recent improvements include renovated hallways and the roof deck, demonstrating the cooperative's commitment to maintaining the property.

The building offers flexible ownership policies, permitting pets, guarantors, co purchasers, pied à terres, and subletting for up to five years after two years of ownership. Residents frequently note the exceptionally low maintenance charges relative to the neighborhood. The location provides easy access to multiple subway lines, the High Line, Chelsea Market, and the area's renowned restaurants, galleries, and cultural attractions.

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.
