Why building skyscrapers and tallest buildings, the purposes, advantages and necessities

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.
And in 2015, the medias reported that a port city in Iraq named Basra plans to build a 1200m tower.
More and more cities are competing to build higher skyscrapers, no matter the population and strength of the city.

However this sort of news raise the questions and critics from some people and groups, including BBC, Daily Telegraph and some so called architecture experts, they doubt the necessity of building the towers that tall, they consider it unnecessary and think it is a waste of money.
Their reason is nothing but something like listed as following, in their eyes, Dubai is a city that has enormous available land to use and no need to cost so much to build the tallest building; Tokyo is regularly influenced by earthquakes then a tallest building built there is inappropriate.
To them building a tallest tower is irrelevant with realistic conditions and have no practicability and necessity.
In fact their statements are complete wrong.

In some cities the usable land is very scare, build higher could maximize the land use rate

First, Dubai seemingly has massive land to build the buildings, but actually usable land is rare, the inland desert is too hot for living, they have to build the building in waterfront spaces and building taller to maximize the space. For this they also build many canals. 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.

Earth quake actually don't affect the security of skyscrapers

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 beautify and modernize the cityscape

In fact the seeming necessity is not the only factor considered by skyscraper developers.
What differentiate us human being from animals is that we are not only after necessity of survival, we also need spiritual enjoyments.
If we just consider what they call necessity then the different styles and colors of our clothes is not needed any more, that is the spiritual pursuit of human make us need those different and colorful styles, and tall building is like such a style, to have a hyper-tall tower added to the city could enriching the skyline to make the cityscape more attractive. Maybe this is why today many star architect is designing skyscrapers more than the traditional buildings.

Some people say the second largest city of America appears like a huge village when they come back from the trip to Los Angeles, feeling that the city lacks of tall buildings.
Although in fact Los Angeles has many skyscrapers, they are generally limit within the downtown area, the overwhelming part of the city consisting mostly of innumerable bungalows. As there’s no traditional tourist attractions before the open of Skyspace on US Bank Tower in downtown, the general foreign tourists can’t notice those downtown towers at all.

Skyscraper is a sign of modern, its existence could deeply affect people’s impression of a city.

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. In short the icon building is an indivisible element of every city.
The most well-known example is Eiffel Tower in Paris. By the time of it was proposed, the tower had been widely criticized by many experts and celebrities, including some familiar people like Maupassant who has been always featured in today’s literature textbooks, but today Eiffel Tower has already become the icon of Paris, and even the symbol of romance.
A landmark building of a city is always a high-rise building, like Eiffel Tower which mentioned above, and such as Empire State Building in New York City, Taipei 101 in Taipei, Petronas Towers in Kuala Lumpur. The intention of Dubai to build a new tallest Tower is to make it become a 21 Century’s Eiffel Tower.
Such landmark buildings could heavily improve the identity of a city, every time someone heard Taipei then think of Taipei 101, heard Dubai then think of Burj Khalifa.

Skyscrapers can improve the value of the land around it

Tower is also an unique addition to landscape, its appearance could significantly boost the value of surrounding proprieties, for instance, a house faces to the sea costs more than ordinary houses and still in great demand, the reason is nothing else than the outside scenery it provided.
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. So a tallest tower is not only providing residences within the tower, but also lots of salable residences surrounding it.

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.
Dubai located at Persian gulf coast, an oil-rich region, the city’s development was mainly relying on oil trade in the past. They realized that oil will be run out sooner or later, began to develop tourism and gradually becomes a pillar industry of the city. The profit brought in by tourism always more obvious, an noted example is Empire State Building in New York City, the revenue generated from its observation is even higher than rental income.

Alongside with the new tallest tower that is being developed by Emaar, some other projects of mega-tall building above 600 meters is also ongoing in Dubai and aimed to be completed by 2020. By constructing so many high-rise towers Dubai is making them as a tribute to the upcoming 2020 World Expo in order to show visitors a new image of the city. In plain words, without these new tall buildings then people come here to see what?
Dubai frequently constructing the tallest towers is closely bound up with its development of tourism industry. As a center of business and tourism in Gulf area, developers in Dubai is developing a quantity of towers for hotels and entertainment, as Dubai plans to double the amount of tourists to 20 million by 2020 from 10 million in 2012.

Skyscrapers can bring numerous job oppotunities

Construction of these skyscrapers could bring the city economic benefit and improving the image of the city, it can also create a multitude of job opportunities, it is estimated that the preparation for upcoming 2020 World EXPO can create 270 thousand employment positions, among them a considerable amount come from construction of high-rise towers.
