Про місце

The structural tube design defines the western edge of the Loop.

Sears consolidated scattered metropolitan offices into a single commercial headquarters on the western rim of the Loop. Skidmore, Owings and Merrill planned the complex on a site bounded by Franklin Street, Jackson Boulevard, Wacker Drive, and Adams Street, closing a block of Quincy Street to secure the full perimeter. Architect Bruce Graham and engineer Fazlur Rahman Khan organized the massing to fit corporate departments.

Gradual setbacks taper the upper stories, providing smaller floor plates suited to general office tenants while reserving broad lower levels for corporate operations. High-speed elevators carry continuous streams of sightseers toward the public observation deck, separating regional office workers from heavy tourist traffic. The surrounding streets stay dense during business hours, shifting into quiet commercial corridors by night.
