The Council on Tall Buildings and Urban Habitat recently published The Tallest 20 in 2020: Entering the Era of the Megatall. Within this decade, the World’s first kilometer-tall building will be constructed, along with many other buildings over 600-meters tall. “The term “supertall” (which refers to a building over 300 meters) is thus no longer adequate to describe these buildings: we are entering the era of the “megatall.”

At the start of the 21st century, the 452-meter high Petronas Tower held the title of “The World’s Tallest”. As the decade ended, the Burj Khalifa took ownership of the title standing “over half a mile” high at 828-meters. Now, construction set to begin this month for Jeddah’s 1,000+ meter Kingdom Tower, doubling the height of “The World’s Tallest” in only two decades. It seems that “600m seems to be the new 300m”.

Check out this skyline diagram illustrating the growing trend of each decade. At the end of 2011, there were only 61 buildings over 300 meters.

“Tallest 20 in 2020” is scattered across 15 cities in 7 countries. China leads the way, claiming 10 of the 20 projects in their pursuit of the supertall, followed by Korea (3), Saudi Arabia (2) and the UAE (2). Asia counts for 70% (14) of the buildings and the Middle East counts for 25% (5).

China’s Shenzhen’s Ping An Finance Center is scheduled for completion in 2015. The 660-meter tall building will become the tallest in the country, offering over 300,000 m2 of office space.

Also currently under construction is the 555-meter, supertall Lotte World Tower, set for completion in 2015. Two other structures, the 620-meter Triple One and the 540-meter Hyundai Global Business Center, have yet to receive planning permission and therefore were not included in this study, proving this list of supertall is quickly expanding.

The CTBUH article concludes asking, “The question for humanity is thus no longer “how high can we build?” but “how high should we build?” Both the benefits and consequences must be considered, as energy implications have us questioning this new building typology.


“Just as we pushed the structural boundaries of height, we must now continue to push the boundaries of environmental engineering in order to progress the tall typology. For, as skyscrapers continue to multiply, their effect on our cities – visually, urbanistically, and environmentally – continues to increase exponentially.”
