The U.S. Steel Building (later known as One Liberty Plaza) was built on the site and completed in 1973. One Liberty Plaza contained per floor, compared with the per floor in the Singer Building's tower. One Liberty Plaza had at least twice the two former buildings' combined interior area. At the time of the Singer Building's demolition, it was the tallest building ever to be destroyed. The record remained until the September 11, 2001, terrorist attacks, which caused the collapse of the nearby World Trade Center. Afterward, the Singer Building remained the tallest building to be destroyed by its owners, until 2019, when deconstruction of the 270 Park Avenue building started in Midtown Manhattan.
