Katerra’s all-encompassing vision of reforming the construction world, using billions of dollars in investment to build an entirely new production system from the ground up, showcased stereotypical Silicon Valley arrogance. It also has had a fraction of the impact of European models that seek to retrofit using a simple, straightforward, and standard set of parts.  The company shared a common blind spot with many American technologists, according to Gerard McCaughey, a serial entrepreneur and founder of Century Homes, an Irish pioneer of off-site construction: it disregarded innovation pioneered overseas. While American construction favored wood-frame building on-site with readily available raw materials—picture a Ford pickup piled with two-by-fours pulling up to a lot—more space- and material-­constrained builders in Asia and Europe have perfected prefab and modular techniques. Katerra ignored these examples, which slowly built up expertise by focusing on specific sectors one at a time. Instead, it tried to reinvent the wheel, bringing every facet of the complex construction process in-house and building too many different models at once and causing massive cost overruns.  “It’s not what you know or what you don’t know that catches you,” says McCaughey, who held talks with Katerra leaders. “There were things they were dead certain you …
