A Year in Review: Trends of 2011 Completion Reaches New High for Fifth Year Running

Chicago January 18, 2012

In January of each year, CTBUH publishes a review of tall building construction and statistics from the previous year. The annual story is becoming a familiar one: 2007, 2008, 2009, 2010, and now 2011 have each sequentially broke the record for the most 200 meter or higher buildings completed in a given year. Once again, more 200 m+ buildings were completed in 2011 than in any year previous, with a total of 88 projects opening their doors. Shenzhen’s Kingkey 100, at 442 meters, tops the 2011 list.

Looking to the future, it is now foreseeable – even through the end of the decade. This hold. Now however, due in large part to the indeed likely – that the recent trend of an represents a change in recent predictions. It continuing high activity of skyscraper design annual increase in building completions will had been expected that skyscraper and construction in China, as well as the continue for the next several years, perhaps completions would drop off very sharply after development of several relatively new 2011, as a result of the 2008 global financial markets, this global dip is no longer expected. crisis and the large number of projects put on The effect this will have on the skylines of the

Before 2011, these cities had a combined total of six 200 m+ buildings. Together, they now contain 34 such buildings and accounted for 32% of completions in 2011, surpassing traditional tall building centers such as Dubai, Shanghai, and Singapore.
