China Built a Skyscraper in 19 Days — And It's Already Falling Apart

China Built a Skyscraper in 19 Days — And It's Already Falling Apart In 2015, a Chinese construction company built a 57-story skyscraper in just 19 days using factory-made modular steel—and the internet couldn't believe it was real. This video breaks down how Broad Sustainable Building pioneered modular skyscraper construction, why their planned 838-meter "Sky City"—set to be the tallest building in the world—was abandoned and quietly turned into farmland, and the hidden engineering risk buried inside every modular high-rise joint that won't reveal itself for decades. We also dig into China's broader construction crisis, from "rotten-tail buildings" and mortgage boycotts to the Evergrande collapse and the Kunming tower demolitions. This is the real story behind China's fastest skyscraper, modular construction technology, and the property crisis unfolding behind the headlines. If you're into engineering documentaries, urban decline, and untold construction history, this one delivers.
