1. The Willis Tower

The Willis Tower is considered to be the tallest building in Chicago and the 23rd tallest tower in the world. It is also said to be the 3rd tallest tower built in the Western Hemisphere. Nested in the heart of the United States, the Willis Tower is a 110-story and 1,451-foot skyscraper. It was architect Bruce Graham and engineer Fazlur Rehman Khan who drew the plans for the tower and the tower opened in 1973. The tower is said to be the most popular tourist destination in Chicago.
1.1 The History of Willis Tower:
The tower occupies a site bounded by Franklin Street, Jackson Boulevard, Wacker Drive, and Adams Street, and behind this innovative idea was the acceptance of Matthew J. Stacom, who was the Vice President of Sears.
Now the question arises, what is Sears and what role do they play in building Willis Tower?
Sears, Roebuck, and Co. was a department store that occupied an office complex on the West side of Chicago since 1906. The department store had many office complexes in Chicago and was quite famous. As the years went by, the company gained more status and opened more stores. By 1966, the office complexes were inadequate to hold down employees and the work needed to manage all the stores. This prompted them to look at other sites for another office complex. They were given two options out of which they chose the place where Willis Tower was built, then called the Sears Tower. Their idea was to merge all the office complexes into one building, the Sears Tower.
Sears purchased 15 buildings from more than 100 owners and closed down a block of Quincy Street to acquire the loop site for Sears Tower.
1.2 The Construction and Design of Sears Tower:
Sears contacted and Commissioned the architecture firm Skidmore, Owings, and Merrill, called SOM, to design the tower. Jaros, Baum & Bolles were contacted for MEP engineering.
It was estimated that the tower would need 4.2 million square feet of land split into 70 stories with 60,000 square feet each to make the tower operational.
Sears in their mind wanted to shift its merchandise group into the tower while renting out the remaining space to other people. The top floors were to be given to the executives of the company. This plan raised concerns about the tower’s design which led to an increase in the height of the tower from the already discussed height to meet all the requirements. The firm Saphier, Lerner, and Schindler was contracted to determine Sears’s space and design requirements. This started a year-long process of research into determining how to fit 16 office complexes into one single building.
Sears contracted the diesel construction company as their contractor. Work on the foundation of the building commenced in August 1970 and through many setbacks, the work was finished and made Sears Tower as Chicago’s tallest building in November 1972.
1.3 Change In History:
In 1984, Sears announced that they would renovate the tower to attract tourists on the lower floors, and a visitor building for the Skydeck was constructed. In the renovations, the building’s entrance was to be covered by a four-story glass dome. The first four stories of the tower were converted into a shopping atrium. All the renovations were completed by mid-1985.
After the renovations, by 1988, Sears decided to relocate its office and sell the tower but they couldn’t find a buyer, so instead they decided to refinance the tower by taking loans from Metlife and AEW Capital Management. Metlife was the major mortgage holder and the deal was that the loan would mature in 2005.
In 1994, Metlife and AEW gained ownership of the tower as Sears relocated their office complex. Trizechanh had acquired the holdings of AEW Capital management and they made some successful efforts to attract tourists to the tower. As the currency grew, they couldn’t keep up with major shareholders vacating the tower, so AEW sold its ownership of the tower all to Metlife.
In 2003, Metlife gained sole ownership of the tower and further sold the tower to an investor group. Even after all the ownership changes, the name of the tower wasn’t changed until an
London-based insurance broker, Willis Group Holdings agreed to take a portion of the tower and gained the naming rights of the tower. The tower was officially renamed as the Willis Tower on July 16, 2009.
In March 2015, the tower was yet again sold and was finally purchased by the Blackstone Group and is still in their possession.
1.4 Skydeck

On June 22, 1974, the Skydeck was finally opened. The observation deck is located on the tower’s 103rd floor and is considered to be the highest observation deck in the U.S. A backup observation deck was opened on the 99th floor of the tower. Standing on the deck, one can experience a tsunami of emotions and views. Looking over the city of Chicago, one can feel the winds and see how the city flows with the winds. The Skydeck became one of the most famous tourist attractions and in the heart of the U.S. 1,353 feet above ground, the deck became one of the spirit-freeing experiences.
1.5 The Final Willis Tower:
Willis Tower under the ownership of Blackstone Group is now a corporate office building, home to different condos and apartments, and more than 100 companies including private law, insurance offices, etc. The tower now includes some of the most luxurious fine dining experiences one can see in Chicago and the observation deck just blows one away with the mesmerizing sights of the city.
