Designed by architects Skidmore, Owings & Merrill, the Sears Tower is composed of nine twenty-three-by-twenty-three-m towers bundled together, a type of design which allows for a building to have unlimited altitude. It is the largest private office complex in the world with a gross area of 410,000 square meters and 109 stories. Occupying an entire downtown Chicago block, the tower is comprised of sufficient steel to build fifty thousand cars, has enough concrete to complete an eight-lane, eight-kilometer-long highway, and enough wire to wrap around the earth one and three quarters times.
西爾斯大廈由建筑師史基摩、歐文斯和米瑞爾設(shè)計。大廈由九座23米見方的大樓組成，這種設(shè)計有無限向上延伸的空間。它是全球最大的私人辦公綜合大樓，占地總面積41萬平方米，樓高109層。大廈可以說占據(jù)了整個芝加哥市中心的街區(qū)，建構(gòu)大廈的鋼鐵足以制造五萬部汽車，混凝土足以建造一條八車道八公里長的公路，電線可以繞地球一又四分之三圈。
