100 William Street was built in 1974 in the Financial District. The 21-story building is notable for its monolithic facade cladding of black slate panels with highly uneven surface and joints, differing considerably from the customary polished stone claddings. The stripe windows change mid-facade to two rows of openings for the HVAC equipment. The floor area is 27,880 m². Within the building there is a public arcade leading diagonally through on street level. The 24 m high space is flanked by chrome-clad structural columns that extend up through the three storeys of office floors opening to the atrium. The atrium pioneered the 1974 zoning revision offering development bonuses for public amenities in an enclosed space -- as opposed to open-air plazas -- with its two levels of retail space and an entrance to a subway station. The bonuses resulted in addition of 5,140 m² of extra leasable floor space inside the building.

In 1974 another revision was worked out with with the Office of Lower Manhattan Development and the architects of the 100 William Street, then in design stage, that stated that covered installations for public, such as subway station entrances, enclosed plazas, passageways etc., would bring building area bonuses for the developers in a ratio of 11:1 (open-air arcades "only" yield a 3:1 return). (The difference between the open-air and enclosed bonuses was used to Sony's advantage in the 1992 public space remodelling of the Sony Building.) Also the minimum dimensions of the arcades as well as the frontage size of the retail spaces and the nature of business within were determined.
