The USG Corporation developed the 35-story 1.1-million-square-foot (100,000 m2) structure originally known as the USG Building as its corporate headquarters building immediately adjacent to and connected to the AT&T Corporate Center in 1992.[1][14] Located at 125 South Franklin Street, the same developers, architects and design teams were chosen, and the two buildings were built jointly as a block-long complex on an 85,000-square-foot (7,900 m2) site.[3][4] They share a 16-story atrium which houses a grand arcade and serves as a common base to the two separate towers.[2] When USG Corporation moved to a new facility in 2007, the building was renamed Franklin Center.[5]
