Like giant exclamation marks, skyscrapers punctuate the story of our urban evolution. From their humble beginnings in the late 1880’s to giants still under construction, they complement and define our contemporary lives. 

Skylines plot the pulse of the world’s greatest cities, with each soaring tower recording a spike in the thrill of urban development. With every generation we are compelled to build safer, to build smarter and clearly, much higher.

Some buildings are monumental – and others – monumentally contentious. From Chicago to London, from Tokyo to Dubai, this is the tale, told by the experts, of many great cities racing to build to the sky.
