Why the U.S. Keeps Making These Blocky Buildings

In Philadelphia, a condo building popped up in 22 months, or half the time it would take typically. That’s thanks to modular construction, where individual units are built in a factory and then shipped and assembled on site. This technique could help reduce costs, time and labor, pivotal in a time when the construction industry is struggling from a worker shortage.

I visited one such factory to see the logistics and construction of these modules — and question how this technique can be used for the skyscrapers of the future.
