Part of the PBS Super Skyscraper series, this video follows the creation of London’s Leadenhall building. The new skyscraper will be built in record time using groundbreaking pre-assembled steel systems; a crew of less than 40 people will wrap its 20,000-ton steel frame in 75,000 square feet of glass.

As urban space shrinks, we build higher and faster than ever before, creating a new generation of skyscrapers. Super skyscrapers are pushing the limits of engineering, technology and design to become greener, stronger, smarter, and more luxurious than their predecessors. PBS’s four-part Super Skyscraper series follows the creation of four extraordinary buildings, showcasing how they will revolutionize the way we live, work and protect ourselves from potential threats.
