The Flatiron Building, originally the Fuller Building, is a 22-story, 285-foot-tall landmark located at 175 Fifth Avenue in the Flatiron District of Manhattan, New York City. Situated on a triangular block formed by Fifth Avenue, Broadway, and East 22nd Street, its distinctive shape resembles a cast-iron clothes iron, hence the name. Designed by Daniel Burnham and Frederick P. Dinkelberg, it opened in 1902 and was initially dubbed "Burnham's Folly". The Flatiron Building anchors the south end of Madison Square and the north end of the Ladies' Mile Historic District. The building was designated a New York City landmark in 1966, added to the National Register of Historic Places in 1979, and a National Historic Landmark in 1989.
The building's facade is designed like a classical Greek column, divided into a base, shaft, and capital. The base is clad in limestone, while the upper stories feature glazed terracotta. The Flatiron Building is known for creating a wind tunnel effect due to its location and shape. As of late 2025/early 2026, the Flatiron Building is undergoing a transformation into luxury condominiums, with sales for the 38 homes expected to launch later in the year and three-bedroom residences starting at $11 million. This adaptive reuse project, led by the Brodsky Organization, involves restoring the building's exterior and completely reimagining the interior for contemporary living, with an expected completion date in 2026.
