Flatiron Building, Fort Worth

The Flatiron Building is located in downtown Fort Worth. At the time of its completion in 1907 it was one of the city's first steel frame buildings and the tallest building in north Texas.

The building was designed by Fort Worth's top architectural firm Sanguinet & Staats in the renaissance revival style. It is constructed of reinforced concrete over a steel frame. The facade is divided into a two-story base supporting a five-story body capped by a heavily ornamented cast iron cornice. The east and west facades are further divided into bays by piers which rise to arches in the top level. The building carries further ornamentation in the form of carved panther heads above the second story and brick lozenges.

Interior design included open floor space to facilitate flexible division into offices. Additionally, "The elevator lobby of the Flatiron, with its handsome Classical details, ceramic tile floor, and marble wainscoting, as well as the ornate iron work of the elevator..." serves to illustrate the attention paid to the public areas of the building in order to entice clients.

The original design specified ten stories, but this had to be scaled back to seven due to budget concerns following the Panic of 1907.

The building is listed in the National Register of Historic Places.
