Overview of The Kensington at 73 Fifth Avenue

The Kensington is an 11 story pre war co op at 73 Fifth Avenue, occupying the northeast corner of 15th Street between Union Square and Chelsea. Built in 1907 as a commercial building designed by Samuel Sass, it was converted to 17 residential co op apartments in 1996, with Joseph Pell Lombardi as architect for the conversion. Its limestone façade is distinguished by rustication, curved window bays, balconies, garlands, lion headed ornament, and a prominent cornice.The apartments have the scale associated with loft living, including high ceilings, oversized windows, open floor plans, and generous living areas. Layouts range from one bedroom homes to large two and three bedroom lofts, with flexible interior walls that allow for reconfiguration. Outdoor space appears in the form of balconies, planting terraces, private roof decks, and other terraces, while a three bedroom duplex places its living spaces on one level and bedrooms above.Building amenities include central air conditioning, resident storage, bike storage, intercom service, and a full time superintendent. The co op is pet friendly and permits live work residences and pied à terres, with co purchasing and gifting considered on a case by case basis. Apartments commonly have hardwood floors, strong southern or western exposures, and private laundry, although these features vary by residence.The building fronts Fifth Avenue one block from Union Square Park and its Greenmarket, with restaurants, shops, and Lower Fifth Avenue close by. The address also sits near the Flatiron District, Greenwich Village, Chelsea, and Gramercy, giving the building a downtown setting anchored by one of Manhattan’s most active public squares.

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.
