The Flatiron Building's facade is divided vertically into three sections, similarly to the components of a classical column. Jacob Garlick agreed to acquire the Flatiron Building at an auction in early 2023, but failed to pay the required deposit, and three of the four existing ownership groups took over the building. Ownership was divided among several companies, which started renovating the building again in 2019. The Newmark Group started managing the building in 1997. Helmsley-Spear managed the building for much of the late 20th century, renovating it several times.

The Equitable Life Assurance Society took over the building after a foreclosure auction in 1933 and sold it to another syndicate in 1945. The Fuller Company sold the building in 1925 to an investment syndicate. A 'cowcatcher' retail space and a one-story penthouse were added shortly after the building's opening.

Construction proceeded at a very rapid pace, and the building opened on October 1, 1902. The Flatiron Building was developed as the headquarters of construction firm Fuller Company, which acquired the site from the Newhouse family in May 1901. The name 'Flatiron' derives from its triangular shape, which recalls that of a cast-iron clothes iron. The building sits on a triangular block formed by Fifth Avenue, Broadway, and East 22nd Street-where the building's 87-foot (27 m) back end is located-with East 23rd Street grazing the triangle's northern (uptown) peak. Dinkelberg, and known in its early days as 'Burnham's Folly', it was completed in 1902 and originally included 20 floors. Designed by Daniel Burnham and Frederick P. The Flatiron Building, originally the Fuller Building, is a triangular 22-story, 285-foot-tall (86.9 m) steel-framed landmarked building at 175 Fifth Avenue in the eponymous Flatiron District neighborhood of the borough of Manhattan in New York City.
