Sears Tower A Building Book from the Chicago Architecture

The nation's largest retailer wanted the largest headquarters in the nation, and they got it. Designed by Skidmore, Owings & Merrill (SOM), the 110-story anodized aluminum-clad Sears Tower occupies three acres. The bundled-tube construction allowed for more windows and more corner offices per square foot. The total area within the Tower is 4.4 million square feet; the Sky Deck on the 103rd floor offers tremendous views and welcomes more than 1 million visitors yearly. When SOM realized that their design was only ten stories short of what was supposed to the record-breaking height of the World Trade Center then under construction (1,368 feet), they broke the record, coming in at 1,454 feet.Pridmore, Jay is the author of 'Sears Tower A Building Book from the Chicago Architecture' with ISBN 9780764920219 and ISBN 0764920219.
