However hard you try you can never get higher. That's because once the tower begins to move, even a little bit, the center of gravity moves and it drives the tower even more towards the direction that it's moving. And that's the reason why Pisa is leaning -- it's a bit like trying to build a tower on a soft carpet."
Recognized by Guinness World Records as the tower with the highest degree of tilt in the world, the 90 foot (27.4 meter) bell tower of this church in Germany has a 5.2 degree inclination. Although the building was built in the mid-1200s, the tower wasn't added until 1450.
Additionally tall buildings should be built before the low-rise buildings, by this way can avoiding the troubles and obstructions come from the NIMBYs in the future.
Skyscrapers can improve the identity of the city. Almost every renowned city has its own landmark building, which is their icon image, it is key component that make the city different from other cities, it demonstrates the strength of the city and stands for the city’s prosperity and development and the soul of the city.
Aside from these two projects, there are some other proposals that also aim to become the tallest skyscrapers, the foremost one is the Jeddah Tower, which is set to be higher than 1 kilometers tall, and has been constructed to a height of more than 200 meters as of March 2017.
This is also the reason that Palm islands and the World islands are being developed. They do this for increasing the usable land. Additionally tall buildings should be built before the low-rise buildings, by this way can avoiding the troubles and obstructions come from the NIMBYs in the future.
Great skyline could also effectively prompt the surrounding proprieties sales, skyline-view houses are similar to sea-view houses as the scenery of tall towers is just as attractive as sea, a great many buyers hope they can see such a magnificent tower from their residences.
Moreover, these days high-rise buildings are considered more environmentally friendly . A city without high-rise buildings must constantly to expand to suburban areas to create more living spaces, in that case, the inhabitants will drive longer distances to get to the city center, thus generating more vehicle exhausts.
The earthquakes in Japan and some other regions actually don’t affect the security of tall buildings, high-rise buildings have been proved to be safer than the low- rise buildings, those buildings collapsed in earthquakes are all low-rise buildings, we never heard a hundreds meters tall building collapsed because of earthquake, with current technology, an 1-kilometer tall hyper-tall tower can resist an earthquake of 9 on Richter scale, in technique earthquakes don’t restrict the height of a building at all.
Skyscrapers can become tourism destinations. The other function of the tall building is attracting more attention from global medias and tourists. When Dubai announced the new tallest building in April 2016, in no time it gets featured in numerous media reports, once again successfully promote this tourism city.
