The Chrysler Building is often called the world's first skyscraper because it was built before the turn of the 20th century. However, according to some historians, this title should go to Paxton Court in London because it was completed earlier than the Chrysler Building (1898 vs 1904). Either way, these are just some of many examples of how early skyscrapers were built. The truth is that they were built by pioneers who had no idea how things would change over time. As technology advanced, so too did the ways inities were designed and built. In fact, the Sears Tower is an example of this as well. When it was being planned in the 1960s, nobody knew what kind of materials could handle such a task or how efficient the construction process would be.
You may have also heard that the Sears Tower is the third highest building in the world. This isn't true either. The Burj Khalifa in Dubai is actually the highest building in the world. It's also worth mentioning that neither of these buildings are classified as "tall" anymore.
Many people are curious about the rationale for the construction of the Sears Tower, which began in 1970 and continued until 1973. It is regarded as one of the tallest structures in the world. It has 108 stories and is located at 233 South Wacker Drive in Chicago, Illinois. The building was designed by Henry Ives Cobb and Alfred Politz who also designed the Tribune Tower, now known as the Pulitzer Building. The total cost of the project was $50 million at that time. It was originally called the John Hancock Center but it is now known as the Sears Tower after it was purchased by Sears Holdings in 1994.
The building's height makes it a landmark in Chicago and its viewable distance on a clear day extends from the shores of Lake Michigan to the Mississippi River. Its unique shape is due to the need to provide clearance underneath to allow for future expansion of the Chicago 'L' system track lines. The building has been listed on the National Register of Historic Places since 1996.
As with most high-rise buildings, the Sears Tower has different floor plans for its rooms. There are two types of rooms: those on the first nine floors are called "express" or "elevator" floors because they can be reached without going through security, while those above ninth floor require access to a special elevator bank for entry. The number of express floors ranges from 9 to 17.
The Sears Merchandise Building Tower was built on South Homan Avenue in Chicago's Lawndale district, four miles west of where its successor would eventually be built. The first tower was just 15 storeys tall, reaching a height of 249 feet. It was constructed between 1973 and 1976 for $20 million (¥150 million; £120 million) as one of two flagship stores for Chicago's Sears Roebuck & Company. The other store was located in Park Ridge, Illinois.
When it was completed, the Merchandise Building was the tallest structure within 20 miles of the city center. It held this title for only three years, until the Trump Tower was built in Chicago in 1978. The Merchandise Building was also the first skyscraper to be made entirely out of glass, steel, and concrete. Its floor space was equal to about 70,000 square feet, and its base was 100 by 250 feet.
The Sears Tower has been called "the world's first luxury condo building" because it was designed with apartments that sold for as much as $500,000 in today's money. It also represented a new generation of skyscrapers that were intended not only for business but also for entertainment. The top of the tower offered visitors a view for up to 50 miles in every direction, which at the time was considered to be quite an attraction.
