Guide to John Hancock Center

John Hancock Center – At a Glance

• Designed by Skidmore Owings and Merrill
• Completed in 1970
• The building is 100 stories
• 700 Privately-owned Luxury Residential Condominiums
• 710-car public parking garage
• Building design eliminated the need for inner support beams, greatly increasing amount of available floor space. Design also minimized the use of steel, saving an estimated $15 million.
• The design concept allows only five to eight inches of sway in a 60mph wind; tested to withstand winds of 132 miles-per-hour.
• The center occupies only 40% of site space, creating rare open space on a bustling thoroughfare.
• The outer skin of high-density black aluminum contrasts with 11,459 extra-thick, glare-proof, bronze glass windowpanes.
• The building is shaped like a wedge, creating the illusion that it is even taller. This was drafted to balance the need for extra parking/commercial space below, and, smaller residential areas above.
