(1943-) Swiss architect. The majority of his work is in Ticino (the Italian canton of Switzerland). A key figure of the Ticino school, his work shows a strong regionalist interpretation of modern architecture, close attention to topography, and a very formal geometry. These aspects are expressed in a striking series of single-family houses, including Riva San Vitale 1972–73 and Ligometto 1975–76.
Other works include a school at Morbio Inferiore 1972–77 and the Staatsbank, Fribourg, 1977–82.
