An architect is "supposed" to draw up some nice plans, hand them to a contractor, and go away. Unless said architect has absorbed Alexander's way of building. That architect is going to make whatever plans the building inspector requires and then work day-to-day on the house, changing, adjusting, making it real in full form.
Great line from Chris about all that: "Architects get paid to pretend they know what's going to be there. But nobody knows until it's there." Many more stories coming about working with Chris—five years' worth, actually.
