A Manhattan skyscraper designed to appear as if gust of wind could topple it over. A Paris museum described as an engineer's "jigsaw puzzle from hell," with 3,500 individually designed glass panels. And a cliffside elevator in Zhangjiajie so remotely located, it had to be built entirely by hand. Join us as we travel the globe to witness astonishing structures that pushed architecture and the laws of physics to the edge. Then meet the brilliant minds who designed and built these wonders and discover the stories behind their construction.

A bent Manhattan building that actually caused panic in the streets. A cultural center in Athens that features a massive floating roof in an earthquake zone. A university complex in stifling Singapore that was built without air conditioning. In this episode, we examine the American Copper Building, the Stavros Niarchos Foundation Cultural Centre, and "The Hive" at Nanyang Technical University, meeting the brilliant minds who designed and built them, and revealing their engineering secrets.

We visit Australia’s One Central Park, The Oslo Opera house and the California Academy of Sciences in San Francisco to reveal their architectural secrets.

We visit London’s Gherkin, Seattles’s Evergreen Point floating bridge and Lyon’s Mysee des Confluences to uncover how and why they were built.

A glass bridge arcing over the Grand Canyon, the weather-resistant Audain Art Museum in Whistler, Canada, and Zaha Hadid's university library in Vienna are explored.

From a logistical railway nightmare to an indoor tropical dreamscape, watch engineers and builders complete the impossible.

Witness a garden in the sky, a pier in the clouds, and a railway station that laughs in the face of natural disasters.

Take a trip to Rotterdam, Guangzhou, and London and witness astounding feats of design and engineering.
