The Business Building is composed of two four-story volumes, the larger housing the undergraduate program and the smaller housing the MBA program. The two masses are unified both functionally and architecturally by the lobby and atrium, Smeal's main gathering and circulation spaces.
The building's formal entry is from tree-lined Shortlidge Road. The entry is marked with a three-story-high canopy and a warm stone façade. Under the canopy, a tall glass wall opens into the lobby and also gives passers-by a view of other activities within the building, especially the adjacent Laboratory for Economics Management and Auctions and the Trading Room.
