Overview of 260 Park Avenue South

260 Park Avenue South stands as a distinguished example of adaptive reuse in Manhattan's coveted Flatiron District. Originally constructed in 1917 as an 8-story neo-Classical building, it served as the headquarters for the United Federation of Teachers for 30 years before being sold in 2003 and expertly converted into an 86-unit luxury condominium by Karl Fischer Architects in 2004. The developers added four floors to the original structure and ingeniously combined it with an adjoining 12-story building at 48 West 21st Street, creating a unique residential complex with a carved-out niche and rock garden that provides enhanced light and air to rear apartments.

The building's 86 residences showcase impressive architectural details, with many units featuring soaring ceilings ranging from 10 to 15 feet, and some boasting dramatic double-height spaces up to 22 feet. Apartments are outfitted with luxury finishes including Calacatta marble countertops, top-tier appliances from Sub-Zero, Viking, and Bosch, and spa-like bathrooms with deep soaking tubs and rain showers. Notable units include duplex lofts with mezzanine levels and corner apartments with expansive living spaces up to 37 feet wide. Many residences offer private terraces, custom built-ins, and the building's signature beamed ceilings that reflect its pre-war heritage.

Residents enjoy white-glove service with a 24-hour doorman and concierge, live-in superintendent, and an impressive array of amenities including multiple landscaped roof decks, a state-of-the-art fitness center, bicycle storage, and parking for approximately 100 cars. The building's prime location at the intersection of Park Avenue South and 21st Street places residents at the heart of one of Manhattan's most dynamic neighborhoods, with immediate access to Union Square's Greenmarket, Madison Square Park, and the area's renowned dining scene, while multiple subway lines provide seamless connectivity throughout the city.
