Skyscrapers are not skyscrapers from the beginning, but they have gone through a long process of change. The first recognized skyscraper in the world is an insurance building. It was first built in 1885. It is located in Chicago, Illinois, USA. Its chief designer is American designer William Jenny. At that time, the building had ten floors and the height reached 42 meters. Although this height is very low now, many skyscrapers are now fifty or sixty stories, and the height of each floor is more than three meters, so many people will think that it is just like that, but this height was already the tallest building at that time.
Five years later, by 1890, there were two more floors in the building, and the height increased to 55 meters. However, this building is also controversial. Some people think that it is not the earliest building, while others question its technical stability. However, it is undeniable that this family insurance building, which was called the earliest skyscraper by Guinness World Records at that time, was very rare in the United States and even the whole world at that time, so it has always been remembered by people because it is the largest in the world.
But this building didn't always exist. It only existed for nearly forty years and was eliminated at 193 1 But when the First World Building is demolished, there will be more and better works. Until modern times, with the continuous progress of science and technology, construction engineering has become more and more powerful. In some ways, machines can replace manpower. Nowadays, skyscrapers are getting higher and higher, which not only reflects the strength of technology, but also makes people understand the importance of architectural aesthetics.
