inputs: hypothesis: The Pritzker Prize is the highest recognition for an architect. premise: The Pritzker jury praised Mr. Zumthor's use of materials. "In Zumthor's skillful hands, like those of the consummate craftsman, materials from cedar shingles to sandblasted glass are used in a way that celebrates their own unique qualities, all in the service of an architecture of permanence," the citation said, adding, "In paring down architecture to its barest yet most sumptuous essentials, he has reaffirmed architecture's indispensable place in a fragile world." Mr. Zumthor said that his projects generally originated with materials. "I work a little bit like a sculptor," he said. "When I start, my first idea for a building is with the material. I believe architecture is about that. It's not about paper, it's not about forms. It's about space and material."
