Peter Zumthor is a highly regarded Swiss architect known for his minimalist and experiential architectural style, winning the Pritzker Prize in 2009. His notable works include the Therme Vals, Kunsthaus Bregenz, and the Bruder Klaus Field Chapel, which emphasize materiality and sensory experience over aesthetic concerns. Zumthor’s philosophy, influenced by phenomenology, focuses on the 'presence' of buildings, which he believes must be experienced firsthand to be understood.
