Chris Alexander likes to make on-site adjustment to a building as it’s being constructed. “Architects are supposed to be good visualizers, and we are,” he says, “but still, most of the time we’re wrong. Even when you build the things yourself and you’re doing good, you’re still making nine mistakes for every success. So you take the time to correct them. The more at each stage you can approach being able to experience the contemplated reality, the more it will give you feedback and you’ll be able to intelligently develop it.”
