Alfred Lerner Hall is the student center or students' union of Columbia University. It is named for Al Lerner, who financed part of its construction. Situated on the university's historic Morningside Heights campus in New York City, the building, designed by deconstructivist architect Bernard Tschumi, then dean of Columbia's Graduate School of Architecture, Planning and Preservation, opened in 1999, replacing the previous student center, Ferris Booth Hall, which stood from 1960-1996.
