The Flatiron Building, also known as the Fuller Building, is a triangular 22-story, 285-foot-tall steel-framed landmarked building located at 175 Fifth Avenue in the Flatiron District neighborhood of Manhattan in New York City. It was designed by Daniel Burnham and Frederick P. Dinkelberg and completed in 1902. The building was developed as the headquarters of construction firm Fuller Company, which acquired the site from the Newhouse family in May 1901. The buildings facade is divided vertically into three sections, similarly to the components of a classical column, and the three-story base is clad with limestone, while the upper stories are clad with glazed terracotta.
The Flatiron Building has been used for commercial purposes since its construction and has housed various tenants over the years. Currently, it mostly accommodates a few publishing companies, with a handful of stores on the first floor. The buildings owners have stated that it will remain an office building and that they are focused on finding the right tenant for the Flatiron. The Flatiron Building is a popular landmark in the New York landscape and is known for its unique triangular shape. Visitors can see the building by taking bus tours, walking tours, or architecture-specific tours.
