A neoclassical skyscraper in the Gramercy neighborhood. The 26-story building, designed by Warren and Wetmore and Henry Janeway Hardenbergh, occupies the western two-thirds of the block bounded by 14th Street, Irving Place, 15th Street, and Third Avenue. It serves as the headquarters of the energy company Consolidated Edison (Con Ed). The site previously housed Tammany Hall and the Academy of Music, along with the offices of Con Ed's predecessor, Consolidated Gas. The company initially operated from its headquarters at 15th Street and Irving Place but needed more space by the 1910s. Hardenbergh designed an expansion for the original building, constructed from 1911 to 1914. This expansion was later integrated into a larger structure built by Warren and Wetmore between 1926 and 1929. Upon its completion, the building's design was praised by local media, and its "Tower of Light" became a notable feature of the skyline. In 2009, the building was declared a New York City designated landmark.
