With 88 buildings greater than 200 m (656 ft) completed last year, the Council on Tall Buildings and Urban Habitat (CTBUH) sees an ongoing trend in an annual increase in building completion.

In 2011, 17 new buildings were added to the list of the world’s 100 tallest buildings. For the first time, the number of office buildings has decreased to the 50 per cent mark, while mixed-use buildings continue to rise, increasing from 23 to 31.

CTBUH’s Nathaniel Hollister toldConstruction Canada Online that 2011 saw several new tall building markets begin to make their mark. The three cities to complete the most +200 m buildings were all relative newcomers to the list: Panama City, Panama, (10 completions), Abu Dhabi, United Arab Emirates (9 completions), and Busan, South Korea (9 completions). Before 2011, these cities had a combined total of six +200 m buildings. Together, they now contain 34 such buildings and accounted for 32 per cent of completions in 2011, surpassing traditional tall building centres such as Dubai, Shanghai, and Singapore.

Existing skyscraper markets––particularly China and the Middle East––are predicted to continue their major roles in the tall building industry. CTBUH also thinks other cities in Central and South America, Asia, and the Middle East will continue to play an increasing role in tall building development.

“We predict that 2012 will see between 75 and 96 200-m buildings complete,” Hollister said. “Unsurprisingly, a large percentage of these will be located in China. Additionally, 2012 will see the completion of the world’s second megatall (+600-m [1969-ft]) building, Makkah Royal Clock Tower Hotel (Mecca, Saudi Arabia).”
