Zurich-based Boltshauser Architekten, which also runs a branch office in Munich, is one of most successful and idiosyncratic Swiss design firms. Precise examination of materials and their constructive potential is combined in their buildings with a profound understanding of ecological issues. Many of their realized designs of varied scale and typology have won international awards. Founder Roger Boltshauser has set himself the goal of finding new forms and solutions for the architectural challenges of our time. The elegant book Roger Boltshauser—Response reviews 12 of Boltshauser Architekten’s key and recent buildings in a three-step presentation of plan, photograph, and sketch. Italian Swiss architecture photographer Luca Ferrario’s atmospheric images, Roger Boltshauser’s own artistic hand drawings, and the sections, axonometries, and floor plans produce a multilayered picture of the practice’s oeuvre.
