Completed in 1902 by Daniel Burnham, the Flatiron Building was a prime architectural design at the advent of steel skyscraper construction in the United States. Known for its triangular design at the intersection of 5th Ave. and Broadway, the Flatiron Buildings iconic presence has transformed an entire area of Manhattan into the Flatiron District.

Built around a skeleton of steel, the Flatiron Building is fronted with limestone and terra-cotta and designed in the Beaux-Arts style, featuring French and Italian Renaissance influences and other trends seen at the 1893 World’s Columbian Exposition.

The building is faced by limestone and glazed terracotta and was designed in the Beaux-Arts style, with Italian and French Renaissance influences. The building was also supposed to feature a clock face on its façade, which was never executed.

The architecture of the Flatiron consists of all aspects of the Chicago school. It has classical Greek column-work and the façade is made up of limestone at the ground level and changes to glazed terra-cotta tiling as the tower moves up.
