The Equitable Building, viewed from street level

The Equitable Building is a famous 36-story office building at 120 Broadway in the Financial District of Lower Manhattan in New York City. A landmark engineering achievement as a skyscraper, it was designed by Ernest R. Graham and completed in 1915. The controversy surrounding its construction contributed to the adoption of the first modern building and zoning restrictions on vertical structures in Manhattan. Although it is now dwarfed by taller buildings in its vicinity, it still retains a distinctive identity in its surroundings on Lower Broadway.

Description

The building in the neoclassical style, rising 538 ft (164 m) with total floor area of 1,206,501 sq. ft (111.500 sq. m), giving a floor area ratio of 30. Upon its completion the building was the tallest building in the world in both height and total floor area. It rises as single tower with the appearance of two separate identical towers standing side by side, connected by a wing for the whole height of the building, such that it appears in the shape of the letter "H" when viewed from above. A striking feature of the building by modern standards is that it has no setback from the street beyond the depth of the sidewalk, rising vertically for all its floors.

The building has a through-block entrance lobby has a pink marble floor, sand-colored marble walls and a vaulted, coffered ceiling. It has approximately 5,000 windows. It once housed the exclusive Bankers Club on its top three floors.

History

The building was constructed as the headquarters of the Equitable Insurance Company. The site had previously been intended in 1906 for 62-story tower designed by Daniel H. Burnham, but the project had been postponed. When the Equitable's previous headquarters were destroyed by fire in 1912, the site was chosen as the location of its new headquarters. It was originally intended to be 40 stories high, but it was reduced by four floors on the advice of consulting engineer Charles Knox, who determined the lower height as being optimal for its elevators.

Opponents of the buildings were outraged at the unprecedented volume of the building, which cast a 7 acre (28,000 m²) shadow on the surrounding streets. Many New Yorkers feared that further construction of buidings like it would turn Manhattan into an unpleasant and dark maze of streets. In response, the city adopted the 1916 Zoning Resolution which limited the height and setback of new buildings in order to allow the penetration of sunlight to street level. Specifically, new buildings were afterwards required to withdraw progressively at a defined angle from the street as they rose, in order to preserve sunlight and the open atmosphere in their surroundings. As a consequence of the new restrictions, the building remained the largest office building by volume in the world until the construction of the Empire State Building in 1931.

The setback code led to adoption of styles such as that of the Chrysler Building and Empire State Building with tiered architecture in its top floors. By the 1960s, many architects had responded to the code by adopting the plaza style of architecture, in which vertical buildings rose from the middle of a concrete plaza, such as the Twin Towers of the World Trade Center.

The stretch of lower Broadway where the building sits has since become the traditional route of ticker-tape parades in Manhattan. The route past the building is known colloquially as the Canyon of Heroes, in part because of the sheer verticality of the building and others around it.
