In the late 1990s, master planning studies were executed to determine the future of the Cooper Union campus. Over the next few years, it was decided that, in order to secure the institution’s financial future, land under the Astor Place parking lot site between Lafayette Street and Fourth Avenue, as well as land under the Albert Nerken School of Engineering Building at 51 Astor Place should be leased to generate income. The Abram S. Hewitt Memorial Building, a two-story structure located on Third Avenue between 6th and 7th Streets, was deemed unsound for the addition of upper levels. The trustees decided to raze the building to make way for a new academic building on that site.

In 2003, architect Thom Mayne was selected to design the new academic building to be located on the site of the Hewitt Building at 41 Cooper Square. Three years later, demolition began. In 2007, a groundbreaking ceremony for the new academic building took place. Two years later, the institution celebrated its 150th anniversary and opened its new academic building at 41 Cooper Square, occupied primarily by the Albert Nerken School of Engineering, the School of Art, and the Faculty of Humanities and Social Sciences.
