How Did They Build That

Wonder at the engineering efforts that created the world’s largest glass roof (which houses a forest of tropical supertrees), watch a major railway station rebuilt during rush hour, and see the creation of the most outrageous structure in Las Vegas.

Uncover how innovative engineers and architects built a stunning viaduct across a beautiful French valley, an extraordinary upside-down hotel in a Chinese quarry, and a forest on top of Italian highrises on a busy suburban train line.

Experience building in the extreme as a radical architect reinvents an ancient Dutch fire station, engineers keep the thinnest skyscraper standing, and Scotland’s wild coast gets a structure that would have been impossible just 10 years ago.

Find the whimsy in architectural feats of engineering, including a giant arch full of apartments built on top of a swamp, a rock-shaped opera house in China, and a British Library roof composed of 1,500 unique glass pieces.
