The next class of skyscrapers, which are being built as the global economy stabilizes, will be taller than their predecessors.

According to Emporis, an international provider of building data, the average height of the 10 tallest skyscrapers currently under construction is 374-feet more than that of the 10 tallest completed in the last decade.

Leading the way is Saudia Arabia’s Kingdom Tower. Designed by Adrian Smith & Gordon Gill Architecture, the 167-floor skyscraper is set to become the first building to break the 1,000-metre mark, which is the equivalent of 3,280-feet. Construction of the tower started in March, and is expected to be complete in 2018. Upon completion, it will be 564-feet higher than the current tallest tower, the United Arab Emirates’ Burj Khalifa, which will become the second tallest in the world.

The next tallest, the Ping An International Finance Center in Shenzhen, China, will tower 2,165-feet. Kohn Pedersen Fox Associates is behind the 115-floor skyscraper as well as two others on Emporis’ list.

Seven of the top 10 buildings are either in or are being constructed in China. Only one tower on the list is in the Western Hemisphere, One World Trade Center. The final spire was added to the New York City tower in May, bringing the height of the building to 1,776-feet.
