Overview of 35 West 23rd Street

35 West 23rd Street is a four unit condominium in the Flatiron District, occupying a restored pre war building originally constructed in 1879. Less than half a block from Madison Square Park and within the Ladies' Mile Historic District, it received the 2024 Lucy G. Moses Preservation Award for its restoration.

The residences are expansive full floor lofts, generally measuring about 3,400 to 3,500 square feet, with ceiling heights ranging from roughly 12 to 14 feet. Their defining architectural elements include exposed brick, timber beams, cast iron columns, oversized south facing windows, and flexible layouts that have been configured as two, three, or four bedroom homes. Private planted terraces or balconies appear in the building's larger loft layouts, along with substantial private storage.

Building features include a restored lobby, video intercom security, porter service, and a planned common roof deck. The condominium also has an arrangement with the neighboring Flatiron House granting residents access to its full time doorman and concierge service and fitness center. Pets and pied à terre use are permitted.

The address is a few doors from Eataly and close to Whole Foods, Trader Joe's, Union Square, NoMad restaurants, and the High Line. The R and W trains stop at 23rd Street on Broadway, while the 6 train stops at 23rd Street and Park Avenue South; the F and M trains stop at 23rd Street and Sixth Avenue.
