Factory-Built Futures: Why Modular Construction Might Win
It covers the engineering case (why a factory's fixed jigs beat a muddy site's improvisation) and the economic one (why shipping a finished module can still beat building everything in place) - illustrated by China's Broad Sustainable Building, which assembled a 57-storey tower in 19 working days after months of factory fabrication, and by a Los Angeles hotel that opened two months early using factory-built bathroom pods.
It is equally honest about where modular has failed: Katerra's near-$2.8 billion in losses and 2021 bankruptcy, and Legal & General's 2023 retreat from its UK modular factory, at a cost of roughly £280 million. Both failures trace to the same cause - a factory only pays for itself with steady, high-volume demand, and ordinary construction demand has never been steady. The video closes on the regulatory, financing and labour barriers still standing in modular's way, and on the 2025-2026 Los Angeles wildfire recovery as the clearest place, right now, where modular is actually winning.
No figure appears without its date, unit and named source. Two figures could not be independently verified against their original source and are marked and explained in this video's fact sheet rather than hidden.
