The Chicago School's skyscraper experience, translated into a difficult Manhattan triangle.
French Renaissance / Beaux-Arts surface detail on an early steel-frame skyscraper.
The Fuller Company assembled the Fifth Avenue, Broadway, and 22nd Street parcel for a headquarters that would turn an awkward block into a skyline symbol.
The building opened as the Fuller Building, designed by D. H. Burnham & Co. with a French Renaissance / Beaux-Arts exterior over a modern steel frame.
The Landmarks Preservation Commission designated the Flatiron Building as LP-0219 on September 20, 1966.
The building was added to the National Register of Historic Places in 1979 and recognized as a National Historic Landmark in 1989.
The Brodsky Organization, Sorgente Group, and partners advanced a private-residence conversion with Studio Sofield interiors.
