As the Council on Tall Buildings and Urban Habitat approaches its 50th anniversary in 2019, this closing session of the core Dubai conference will examine how far tall buildings and cities have come in the past 50 years, and speculate on where they might be in 50 years from now. With a tremendous confluence of technological change and new design thinking happening today, the stage is set to guide the next generation of “sustainable vertical urbanism”. Four prominent speakers deliver their vision of “50 Forward, 50 Back”.
