Modular apartment buildings?

City Lab - Can a factory produce a cheaper apartment? Modular building has long been seen as a way to disrupt the construction industry, and in Chicago, one builder is making a serious play to bring it to fruition. The company, Skender, is fine-tuning its operations in a 100,000-square-foot factory that can produce a quintessential Chicago three-flat apartment building in 90 days, compared to nine months via traditional construction. The grand vision is for an assembly line that saves time and brings down costs, too.
