Exploring the engineering and architectural masterpieces like The Copper in Manhattan to Gardens By the Bay in Singapore.

Milwaukee commissions Calatrava to design a museum with 90-ton wings that take flight; Oslo tears down its national ski jump and rebuilds it for the World Championships; and in LA, a 235-foot tower is wrapped in steel bands.

In Oklahoma, a sacred spiral mound rises on a former oilfield, honouring 39 tribes; London's crumbling Battersea Power Station is reborn with two million new bricks. And in Spain, Frank Gehry crowns a historic winery.

Engineers create impossibly shaped buildings: Albany's Egg, a huge, sculpted theatre space, fit for a Rockefeller; a floating fortress in LA, protecting $2bn in art; and giant New York offices towering over America's busiest com.

Witness amazing buildings, bridges, lifts, and other structures that pushed structural concrete engineering to the edge.
