Skyscrapers are either residential or office buildings with a height no less than 100-150 meters. The idea of skyscrapers first appeared in the United States, marking the beginning of high-rise construction using newly developed technology.  

For a long time, the world had rarely experienced height in constructed buildings. Most buildings at the time were built between a maximum of 6 to 7 floors and that was considered a rare and wondrous site. The end of the 19th century and beginning of the 20th marked the beginning of high-rise construction, when American engineers began to reinforce concrete and steel building frames. The development of high-rise construction was interconnected with new approaches in design, and especially with the invention of safe construction elevators. 

Today, skyscrapers are an integral part of most megacities. High-rise buildings are typically occupied by offices of international companies and banks, business centers, hotels, and residential apartments.

As for the height, there is no concrete definition outlining the exact number of meters needed for a building to be considered a skyscraper. Usually, buildings with the height of 100-150 meters are referred to as skyscrapers. 

Today, there are approximately 4 thousand skyscrapers around the world, especially in the United States. In fact, Chicago and New York were the first states to ever  have high-rise buildings built and were even the first to ever nickname them ‘skyscrapers’. The famous Empire State Building (449 meters), built in 1931 in New York, is among the top five highest towers in the world. However, the highest skyscraper today is actually considered to be Burj Khalifa in the United Arab Emirates, standing at the height of 828 meters. Currently, China, Hong Kong, Macau, Singapore, Australia and other countries are actively building up skyscrapers.

Russia has its own skyscrapers, including the complex of towers known as ‘Moskva-City’. Other famous towers include the Stalinist skyscrapers, such as the Moscow State University tower that exceeds 240 meters.

The cost of buying or renting an office (or dwelling) in skyscrapers usually depends on the floor level. The higher the floor, the higher the price.
