America has so many stories to tell. And nobody brings them to your home like Smithsonian Channel.

On inadequate foundations, San Francisco's MOMA triples in size creating an exterior light enough to prevent collapse; a 1970s Sydney skyscraper is recycled into a 21st century tower; in Dallas, a five acre park is created.

How Did They Build That?

Floating Parks & Upcycled Towers

A 70,000-seat stadium defies seismic forces and international flight paths in LA. Zaha Hadid's dramatically twisted 33-story tower rises around ancient vaults in Malta.

Super Stadiums & Extraordinary Elevators

A new museum building bends 1,100-glass tubes to form a facade and tunnels below the water table. A vast 11-storey glass atrium HQ is built on the former Berlin Wall site to represent unity.

Facelifts & Scaffolds

A 284ft wooden skyscraper built from 1,200 bespoke pieces tests fire safety limits in Milwaukee. A decaying Amsterdam crane track transforms into elegant glass offices.

Shipyards & Slender Builds

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

Ecobuilds & Earthquakes

Defy gravity in an Amsterdam high-rise that hangs 164 feet above the water; marvel at three interconnected towers in Chicago that have a road running through them; examine the revolutionary framework of Paris' controversial Pompidou Centre.

High Waters & Harsh Winds

Paying tribute to the brave, gravity-defying design of the U.S. National Medal of Honor Museum; traveling to Singapore for a look at a leaning tower of gambling, then exploring a New York City office building that lets the sun shine through.

Medals & Marinas

Celebrating one of humanities biggest engineering achievements, the International Space Station, a meteor proof lab bigger than a football field, constructed by astronauts traveling 250 miles above us at 17,500 miles an hour.

Space Stations and Super

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