Frank Schneider, Cornelia Mattiello-Schwaller and Mike Mattiello, all three of whom were born in Solothurn but are now based in Zurich, have produced numerous competition successes. They became internationally renowned with their metal workshop design for the Zurich Dynamo youth centre, which was designed in a gripping "unity of materials". This volume compiles the buildings and projects they have produced since then. Text in German with an English insert.
