Broad Exchange Building

The Broad Exchange Building, also known as 25 Broad Street, is a residential building at Exchange Place and Broad Street in the Financial District of Lower Manhattan in New York City. The 20-story building was designed by Clinton & Russell and built between 1900 and 1902. The Alliance Realty Company developed the Broad Exchange Building as a speculative development for office tenants.

The Broad Exchange Building is either 20 or 21 stories tall. its articulation consists of three horizontal sections similar to the components of a column, namely a base, shaft, and capital. The lowest three stories of the facade are clad with rusticated granite blocks; the fourteen-story shaft is clad with brick; and the top stories are clad with granite and terracotta, topped by a copper cornice. Inside, the building originally contained office space, but as of 2019, has 307 residential units. With 326,500 square feet (30,330 m²) of rental space in total, the Broad Exchange Building was Manhattan's largest office building upon its completion.

Due to the Broad Exchange Building's proximity to the New York Stock Exchange Building, many financial firms sought space in the building. The Broad Exchange Building was sold off numerous times in the late 20th and early 21st centuries. The Broad Exchange Building was gutted and renovated into apartments in the late 1990s, and a southern wing of the building was demolished in the early 21st century. The building was added to the National Register of Historic Places (NRHP) in 1998, and was designated a city landmark by the New York City Landmarks Preservation Commission in 2000. It is also a contributing property to the Wall Street Historic District, a NRHP district created in 2007.
