The Council on Tall Buildings and Urban Habitat’s Year in Review: Tall Trends of 2012 is filled with statistics and observations on tall buildings, from 2012, trends from 1960-2014, by location, material, and function, and by global region.
Although the pace of completions slowed in 2012, there is no indication of a tall building construction slowdown. As 2012 closes, the industry is on the cusp of another burst of tall building development. In total, there are 437 buildings taller than 200 meters under construction globally. It is likely the 2013 completion total will set a new record for tall building completions, surpassing the 2011 total.
