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 (for an overview of all 200 m+ buildings, see the “Tall Buildings in Numbers” study). Shenzhen’s Kingkey 100, at 442 meters, tops the 2011 list.
Looking to the future, it is now foreseeable – indeed likely – that the recent trend of an annual increase in building completions will continue for the next several years, perhaps even through the end of the decade. This represents a change in recent predictions. It had been expected that skyscraper completions would drop off very sharply after 2011, as a result of the 2008 global financial crisis and the large number of projects put on hold. Now however, due in large part to the continuing high activity of skyscraper design and construction in China, as well as the development of several relatively new markets, this global dip is no longer expected. The effect this will have on the skylines of the world will be tremendous (see “The Tallest 20 in 2020” article for more on the future of the skyscraper).
The buildings completed in 2011 have effected a significant change in the world’s tallest 100 buildings, with 17 new buildings added to the list. This change continues the trends of recent years (see Figures 2–5). Perhaps most significantly, for the first time in history the number of office buildings in the tallest 100 has diminished to the 50% mark, as mixed-use buildings continue to increase, jumping from 23 to 31. As recently as the year 2000, 85% of the world’s tallest were office buildings – meaning that a 35% change has occurred in just over a decade. In terms of location, Asia, now with 46 of the 100, continues to edge toward containing half of the world’s tallest buildings. The Middle East region saw an increase of three, while Europe diminished to only one building in the tallest 100: Capital City Moscow Tower.
