How did Dutch engineers build a massive new horseshoe-shaped complex full of apartments on top of a swamp? How did the simple inspiration for a Chinese opera house lead to one of the most advanced buildings in the world? And how did a 180-year-old British structure find its place in the modern world? Meet the visionary designers and brilliant engineers behind the Rotterdam's Markthal, the Guangzhou Opera House, and the Great Court of the British Museum, and discover the behind-the-scenes stories of how they were built.

Every construction job comes with obstacles...but some are much bigger than others. In this episode, we travel to the world's most extreme climate to see how engineers built the British Antarctic Survey, a research station that can move locations when danger strikes. Then we visit the Auditorio de Tenerife in the Canary Islands, with an exterior so revolutionary, a new machine had to be custom built to make it. Finally, we head to Scotland's Falkirk Wheel, a rotating boat lift that connects two canals with massive height differences.
