According to public television RSI, Mr. Snozzi died the day before in a retirement home in Minusio, in the Italian-speaking region of Ticino.
The architect mainly worked in his native region, with characteristic constructions based on exposed concrete.
"Any intervention implies destruction. You must destroy conscientiously, with joy," he often declared.
He was one of the eminent figures of the school of architecture in Ticino, alongside his colleagues Mario Botta and Livio Vacchini, and championed the idea of rational architecture.
His main creations of houses, of which the Snider and Cavalli mansions, in Verscio, are the best known, as well as urban development projects, such as that carried out in the convent of Monte Carasso.
Luigi Snozzi represented Italy at the Venice Architecture Biennale in 1996 and won the prestigious Meret Oppenheim Prize in 2018, which recognizes the best Swiss artists.
He was also a professor at the École Polytechnique Fédérale de Lausanne.
