Work is finishing up on the residential conversion of the Flatiron Building, a 22-story landmark at 175 Fifth Avenue in Flatiron, Manhattan. Originally designed by Daniel Burnham and completed in 1902 as the Fuller Building, the 285-foot-tall structure is being redeveloped by the Brodsky Organization and the Sorgente Group, with SLCE Architects serving as executive architect, Beyer Blinder Belle Architects & Planners as historic preservation consultant, and Studio Sofield designing the interiors, and yields 36 condominium units. Remaining residences are expected to be completed by the end of the year, with the full amenity collection to follow in early 2027, according to the development team.
Since our last update in March 2026, when scaffolding removal had begun along the exterior, crews have completed the multi-year restoration of the building’s Beaux-Arts façade. The scope of work included the repair of its limestone, brick, and terracotta cladding, the restoration and replication of thousands of individual terracotta elements, and the replacement of more than 1,000 windows, executed in coordination with the New York City Landmarks Preservation Commission. With construction complete, the first residents have begun moving in, marking the first residential occupancy in the building’s 124-year history.
The steel-framed structure culminates in a 6-foot-tall cornice, which was repaired as part of the restoration. Below it, an LED illumination scheme designed by L’Observatoire International and approved by the Landmarks Preservation Commission will light the upper stories at night for the first time in the building’s history. The refurbished ground-floor frontage along the pedestrianized Broadway plaza will be home to Bar Pisellino Flatiron Building, a restaurant from restaurateurs Rita Sodi and Jody Williams expected to open in 2027.
Residences are shaped by the building’s triangular massing, with north-facing units overlooking Madison Square Park from the prow. Interiors feature private elevator entry vestibules with marble mosaic flooring and kitchens with metal cabinetry, and incorporate historic ironwork, railings, and marble mosaics uncovered during the restoration. Amenities include a 60-foot lap pool, a fitness center, a sauna and cold plunge, a sports and golf simulator, and lounge and game rooms, with private storage and wine cellars also available.
The Flatiron Building spent more than a century as a commercial property, most notably as the home of Macmillan Publishers, which departed in 2019 after nearly 60 years. An ownership group including GFP Real Estate acquired the property for $161.5 million at a March 2023 auction and later brought on the Brodsky Organization to lead the redevelopment.

It seems the ornate exterior requires major repairs every few years. I hope the buyers realize what costs they are assuming.
This isn’t a box though
The Fuller Company invented the general contractor and built many famous buildings, including its own NY office building. Skeptics feared the building would topple and it soon became called the Flatiron for its triangular shape. The company’s next office building at 57th Street, is a sublime Art Deco design that the company was determined would not receive a nickname.
Now, the full floor penthouse is asking for a mere $53 million.
Barely one and half apartments per floor?
Unmentioned is the costly and likely complex addition of modern climate control, replacing individual units mounted in the windows over the years.
