Related Sales just unveiled the nearly 7,000 square-foot triplex penthouse and 6,620 square-foot duplex residence in the Flatiron condo building, One Madison.
Both residences feature half-floor master suites and 360-degree panoramic views from the river-to-river-to-sea. With incomparable postcard views, expansive entertainment spaces and luxurious living quarters, the residences epitomize Manhattan living at its absolute peak.
The slender 60-story bronze glass tower with award-winning architecture by Cetra/Ruddy and interiors by Yabu Pushelberg overlooking Madison Square Park is already over 60% sold with additional units recently coming to market. The triplex penthouse is priced at $50m and the duplex is priced at $37.5m.
The triplex penthouse, poised at the crown of One Madison, spans three full floors and offers nearly 7,000 square feet of interior space and a 586 square-foot wraparound terrace — one of the city’s highest private terraces.
Residents enter the penthouse on floor 58 through a private foyer accessed by a keyed elevator and encounter an expansive double-height Great Room with dramatic floor-to-ceiling windows. The 58th floor also features a corner eat-in kitchen with an oversized island for entertaining, terrace access, a formal dining room, corner library and a sweeping circular staircase along with a private internal elevator to serve the penthouse exclusively.

The second floor of the penthouse, floor 59, features a guest bedroom with adjacent bathroom, corner media room, and staff bedroom with en suite bath and laundry room. Atop the residence on the 60th floor, rests the half-floor master suite with triple-exposure views to the north, east and south and featuring a windowed walk-in-closet and dressing room, and corner master bath with soaking tub and oversized windowed steam shower.
Two additional bedrooms with en suite baths are also located on this floor. The residence presents unparalleled views from every room throughout the day: admire the new World Trade Center at breakfast in the eat-in kitchen; gaze upon six of the city’s most iconic bridges from the master suite; enjoy a close-up of the Empire State Building from the dining room; and marvel at the dramatically changing landscape of Manhattan’s West Side with awe-inspiring sunsets from the media room. The penthouse is available as an unfinished space for personal customization or designed and finished by internationally renowned Yabu Pushelberg.
The four-bedroom duplex residence, on floors 55 and 56, features 6,620 square feet of living space. Residents enter on floor 55, which offers an oversized great room with north, west and east exposures that is perfect for gathering, a spacious corner eat-in kitchen with adjacent formal dining room, corner media room with en suite bath and guest bedroom with en suite bath. Standing in the great room, residents can look north, south, east and west at once. The 56th floor boasts a luxurious half-floor master suite with views to the north, west and south, sitting area, dressing area and walk-in closet, and corner master bath with soaking tub and oversized windowed steam shower, plus two additional en suite bedrooms and an open plan media room.
“One Madison’s penthouse and duplex residences exemplify the very best of Manhattan living. With breathtaking views, expansive layouts and no detail left unattended to, these residences are truly in a class all their own. The boutique nature of the slender and intimate building also offers residents over 10,000 square feet of amenities on the fifth and sixth floors, that will serve as an extension of their home and cater to every need of their lifestyle,” said Leslie Wilson, senior vice president of Related Sales and Director of Sales at One Madison.
“The exceptional pace of sales over the past few months has been amazing, with many sales exceeding $4,000 a square foot and we are thrilled with the response we have received from the marketplace and New York buyers to this unique offering.”
The interiors and amenity spaces, curated by Yabu Pushelberg, set a new standard for intimate urban living. The property offers a vast private amenity space across two full floors, One Club, which will serve as a 10,000-square foot extension of one’s home.
An elegant lounge, parlor and screening room offer space for relaxation or entertaining, featuring beautiful views of Madison Square Park through floor-to-ceiling windows, and private parties in the dining room are facilitated with ease from the catering kitchen and enhanced with butler service.
An additional floor offers a 50-foot indoor pool with bold marble-clad walls, state-of-the-art fitness center, yoga room, a sculptural glass-enclosed steam room, and children’s playroom. One Club also offers 24-hour service including on-site expert concierge and butler staff, to support everyday needs as well as access to the most desirable entertainment destinations, coveted restaurants and lifestyle experiences in New York City and worldwide.
