Construction of the Willis Tower began in 1970 and was completed in 1974 at the cost of $150 million.

The original building, the Sears Tower, was designed by chief engineer Bruce Graham of Skidmore, Owings & Merrill and structural engineer Fazlur Khan of the same company. The Willis Tower was built on a series of nine independent tube structures, which allowed for increased strength and flexibility. The Willis Tower is clad in stainless steel, bronze, and aluminum and features an open-air observation deck. Additionally, the building was designed to be energy efficient, making use of natural air flow to reduce energy consumption.

The total cost to construct the Willis Tower was an estimated $150 million. This figure includes the cost of materials, labor, construction equipment, and other related expenses. The total cost of the construction was paid for by Sears Roebuck and Company, which occupied the building until 1995. The building itself was sold to Blackstone Group in 2004 for a reported $840 million.

Today, the Willis Tower continues to be a popular tourist destination. Visitors can enjoy the observation deck, ride the Skydeck Ledge, shop in its stores, or take in the 360-degree views of the city. Additionally, the Willis Tower has become the focal point of the Chicago skyline due to its iconic shape and its height.
