The Flatiron Building was designed by Chicago's Daniel Burnham in the Beaux-Arts style. Like a classical Greek column, its limestone and glazed terra-cotta façade is separated into three parts horizontally. Since it was one of the first buildings to use a steel skeleton, the building could be constructed to 285 feet (87 m), which would have been very difficult with other construction methods of that time.
The initial design by Daniel Burnham shows a similar design to the one constructed, but with a far more elaborate crown with numerous setbacks near the pinnacle. A clock face can also be seen. However, this was later removed from the design.
