The building is affectionately referred to as ‘Big John’. It is one
of Chicago’s most revered skyscrapers. Completed in 1970
and
measuring 344 meters (1127 feet) its distinctive design is the
brainchild of Bruce Graham and Fazlur Khan of Skidmore,
Owings and
Merrill. These two renowned architects also designed the
Sears
Tower, the tallest building in Chicago since 1974.
One of the main attractions of this 100-story building is its exterior cross bracing. Over and above its esthetic value, this unique design adds structural stability and helped cut construction costs by 50%. The John Hancock Center gradually rises from 3716 meters squared (40,000 square feet) at the base to 1,672 meters squared (18,000 square feet) at the summit. Offices and stores occupy the lower floors. The top 49 floors are for residential units and apartments. An observatory on the 94th floor provides tourists with a breathtaking view of the city and Lake Michigan.
