The main building for the Fulton Center project, referred to as the Fulton Building by the MTA in its Requests for Proposals in August 2012, is a three-story building clad in glass, with an oculus atop that draws natural light into the main building and the uptown platform of the Lexington Avenue Line station. It is designed by Nicholas Grimshaw and James Carpenter Design Associates. Its construction replaced four buildings along the eastern side of Broadway, which were demolished during 2007.
