Over a decade ago, I trundled my good-natured family across miles of southern Switzerland to see every building I could by Peter Zumthor, who is this year's winner of the Pritzker Prize. Then as now, most of Zumthor's work was off the beaten track, not only literally but metaphorically, little known to the general public although admired by professionals. What drew me to make the trek to his work was what, from pictures, appeared to be its conceptual rigor, its unabashed monumentality, and an attention to detail so fanatical that every threshold, corner, and joint seemed to become an opportunity to rethink the way hands make buildings.
