Tall Buildings in Numbers
In the past few years, the tall building industry has become increasingly interested in the use of timber as a major structural element in skyscrapers. This has resulted in in a now-worldwide wave of research, built projects, and ever-more daring speculative proposals using "mass timber" – engineered wood products that are just as robust as their concrete and steel counterparts. In 2008 there was one mass timber building over eight stories tall. Today, there are nearly 40 complete, under construction, or planned. (Council on Tall Buildings and Urban Habitat)
