SOM Transforms the Skydeck of Willis Tower

After an extensive renovation, Skidmore, Owings & Merrill (SOM) completes the transformation of the Willis Tower observation deck and inaugurates a new interactive exhibition showcasing how architecture shaped Chicago’s identity through the city’s history. Now reopened to the public, the Skydeck is part of SOM’s ongoing design stewardship of Willis Tower, which started with the building’s conception and continued in 2009 with the addition of the Ledge.
