The Flatiron Building, the historic triangular tower at 175 Fifth Avenue, is nearing a sellout as its transformation from longtime office building to luxury condominium comes closer to completion. According to the New York Post, 82% of the 22 residences that had been publicly offered were already in contract as of mid-August, leaving only a handful of available homes.
It is a notable response for a residential project positioned firmly at the upper end of Manhattan’s luxury market, with prices beginning at just under $11 million and reaching $58.5 million for a full-floor penthouse.
From New York Office Icon to Private Residences
Completed in 1902, the Flatiron Building has been part of the Manhattan skyline for more than a century. The landmark was originally known as the Fuller Building and became famous for its narrow, wedge-shaped footprint where Fifth Avenue and Broadway meet near Madison Square Park.
For most of its history, the building served commercial tenants. Its longtime occupant, Macmillan Publishers, left in 2019, opening the door to a dramatically different future for the property. After a complicated auction process in 2023, the existing ownership group secured the building for $161 million and later brought in the Brodsky Organization as part of its residential redevelopment.
The result is the first opportunity in the building’s history for New Yorkers to actually call the Flatiron home.
Designing Around an Iconic Shape
Turning a turn-of-the-century office landmark into modern luxury residences presented an unusual architectural challenge — particularly because of the building’s famous triangular footprint.
Studio Sofield was brought in to design the interiors, incorporating the Flatiron’s unusual angles rather than attempting to disguise them. Many floors were configured with a north-facing and south-facing residence, while the upper portion of the building includes expansive full-floor homes.
Original architectural character has also been woven into the new interiors. The building’s exposed structural steel, unusual window configurations and historic proportions help distinguish the residences from more conventional new-development apartments.
The conversion is expected to include 38 condominium residences in total.
Luxury Buyers Have Moved Quickly
Sales began quietly before becoming public earlier in 2026, and several high-priced contracts quickly followed.
One of the more notable deals came in March, when a full-floor seventh-story residence asking $30.5 million found a buyer. The approximately 7,700-square-foot home had initially been conceived as two separate apartments before the developers combined the spaces into one expansive residence.
Another residence asking $24.8 million also entered contract earlier this year, while an 18th-floor home asking $15.65 million later found a buyer. At the top of the market is a five-bedroom, full-floor penthouse on the 21st floor asking $58.5 million.
The pace of sales is particularly significant given the price point. Rather than competing solely on newly built architecture or record-setting height, the Flatiron offers something that cannot easily be recreated: the opportunity to own a private residence inside one of New York’s most internationally recognizable buildings.
Historic Architecture Meets Modern Amenities
While preserving the Flatiron’s landmark character has been central to the redevelopment, its interiors are being equipped with the amenities expected in today’s luxury condominium market.
Residents will have access to a wellness and fitness program that includes a 60-foot lap pool, fitness center, sauna and cold plunge, along with spaces such as a billiards room and residents’ lounge.
The restoration work outside the residences has been equally extensive. Approximately 1,000 windows have been replaced in accordance with landmark requirements, while the building’s historic terra-cotta and limestone exterior and prominent rooftop cornice have undergone restoration. The project is also introducing exterior architectural lighting to the Flatiron for the first time.
A New Chapter for a New York Landmark
More than 120 years after it first appeared on the Manhattan skyline, the Flatiron Building is being reintroduced to New York in a completely different way.
Its transformation also illustrates the continued appeal of properties that combine architectural significance, scarcity and modern luxury — particularly at a time when buyers at the highest end of the market have an increasingly wide selection of new developments to consider.
The Flatiron, however, offers something fundamentally different. Buyers are not simply purchasing a luxury condominium; they are purchasing a home inside a piece of New York City history.
Initial move-ins are expected to begin in fall 2026, with the complete amenity offering anticipated to follow in early 2027.
