Description
A rare opportunity to create your own full-floor loft in the heart of Flatiron. Accessed via key-locked elevator, this sprawling 4,100-square-foot residence occupies the entire third floor of an intimate prewar cooperative. Residence 3 presents an exceptionally rare chance to craft a bespoke floor-through home tailored to your vision and lifestyle. Defined by its extraordinary proportions, the loft features 11.5-foot beamed ceilings and nine oversized south-facing windows spanning nearly 50 feet across the building's facade. Natural light pours into the space throughout the day, accentuating the loft's volume & original features, while creating an atmosphere that is dramatic yet inviting. The scale offered here is increasingly difficult to find in today's market - expansive entertaining area, multiple living spaces, and private quarters of unmatched proportions. The flexible footprint can accommodate a variety of layouts, including three to four bedrooms, a home office, media room, library, and multiple baths. Whether conceived as a classic, wide-open downtown loft or a more contemporary residence, the possibilities are virtually limitless. Alternate floorplans are available and illustrate the potential to transform the space into one of Flatiron's most distinctive homes. Built in 1906, 15 West 24th Street is a boutique cooperative comprised of just ten residences. Perfectly positioned where Flatiron, NoMad, and Chelsea converge, the building offers an exceptional downtown lifestyle just moments from Madison Square Park. Residents enjoy unparalleled access to some of Manhattan's most celebrated dining destinations, as well as an ever-evolving collection of acclaimed restaurants, cafés, and boutiques. Everyday conveniences are equally close at hand, with Eataly across the street, and both Whole Foods & Trader Joe's nearby. The location is exceptionally connected, with multiple subway lines accessible from the 23rd Street stations (4/5/6, R/W, F/M & 1). Building amenities include a full-time superintendent, communal roof deck, video intercom, and Verizon FiOS connectivity. This pet-friendly cooperative permits pieds-à-terre ownership and allows subletting on a case-by-case basis.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
