The most modern buildings.

The most modern buildings.At the beginning of August 2017, there are 95 ultra-high skyscrapers in the world. Architects around the world are trying to surpass previous achievements. With the development of technologies, the invention of modern building materials and the creation of fundamentally new structures, it became possible to erect buildings above 300 meters. Until the 19th century, increasing the height of buildings meant thickening the walls, which had to support the weight of the structure. Creating elevators and metal frames for walls freed the hands of architects and engineers. Now the tallest buildings in the world are striking in their grandeur and technical novelty.
2017 was a record year for the construction of skyscrapers, according to Designtalk. Last year, the construction of 144 skyscrapers with a height of more than 200 meters was completed. Tall buildings appeared in 69 cities in 23 countries, which is significantly more than in 2016 (54 cities and 18 countries).
