Switzerland/Austria Study Tour In February 2003 the Landscape + Urbanism unit undertook a study tour of Switzerland and Austria, which also briefly encompassed Liechtenstein, France and Germany. We saw some exemplary buildings by architects such as Diener & Deiner, Gigon & Guyer, Baumschlager & Eberle, Herzog & de Meuron, as well as works by Nouvel, Zumthor, Gehry, Hadid, Siza, Ando and Piano.
