The development of Swiss architecture over the past thirty years can be interpreted as a sequence of "moments" against the background of different geographical, cultural and linguistic zones. One such "moment" is the work of the 40-year-old Genevan architect Andrea Bassi. Raised in the Ticino and educated in Lugano and Geneva, his work already evidences some unmistakable characteristics, whereby he derives his powerful reduced forms from the site of the building. Martin Steinmann, a well-known architectural critic and teacher at the EPF Lausanne, analyses some of the aspect in Andrea Bassi's architecture. Five buildings and projects are presented in short texts, plans and photographs.
