Description

AN ICONIC NEW YORK LOFT, UNTOUCHED FOR 45 YEARS Some New York apartments have a story. This is one of them. Offered for the first time in 45 years, Residence 10N at 40 West 24th Street is an extraordinary opportunity to create a one-of-a-kind home from one of the increasingly rare authentic loft spaces that define downtown Manhattan living. Spanning approximately 3,000 square feet in the heart of the Flatiron District, this sprawling prewar loft has remained in the same ownership for nearly half a century. Idiosyncratic, deeply personal and unmistakably New York, it is a home shaped over decades rather than designed for a moment. Eleven enormous arched windows stretch across the residence, filling the loft with natural light and giving the space its remarkable architectural presence. Approximately 12-foot ceilings, exposed brick, original columns and expansive open proportions provide the bones of a classic Manhattan loft and an exceptional canvas for architectural transformation. Adding to its distinctly old New York character, the residence also has its own private elevator, currently out of service, with the potential to be restored as part of a future renovation. For a buyer searching for a true NYC renovation opportunity, 10N offers the chance to start with the things that simply cannot be recreated: scale, volume, history and authentic architectural character. The existing three-bedroom, two-bath residence can be completely reimagined into a spectacular custom home, whether envisioned with a dramatic great room, expansive chef's kitchen, serene primary suite, additional bedrooms, home office, library or studio. And perhaps the most exciting possibility lies directly above. More than 1,000 square feet of private outdoor space and exclusive roof rights sit directly above the residence. Subject to all required cooperative and governmental approvals, there is the potential to create direct access from the apartment to the private roof, transforming the property into an extraordinary indoor-outdoor New York City home. Imagine an architectural staircase rising through the loft to a landscaped private rooftop retreat. Gardens, outdoor dining, entertaining and open sky above; approximately 3,000 square feet of quintessential New York loft living below. Taken together, it is an opportunity that is increasingly difficult to find in Manhattan: a large-scale Flatiron loft with soaring ceilings, oversized arched windows, exposed brick, original architectural details, a private elevator, more than 1,000 square feet of private outdoor space, and the potential for a directly connected private rooftop. This is not a newly renovated apartment designed around someone else's taste. It is a chance to work with an architect, preserve what makes a true New York loft special and create a home entirely your own. 40 West 24th Street is a boutique prewar cooperative with keyed elevator access, ideally positioned in the heart of Flatiron, moments from Madison Square Park and at the crossroads of NoMad, Chelsea and Greenwich Village. After 45 years with the same owner, this singular piece of New York is ready for its next chapter. Bring your architect. Bring your imagination. Create your dream New York loft.
