This book is the first, long-awaited monograph on the oeuvre created by this young practice over the last ten years, from their first efforts in Davos (Switzerland) to their recent projects for the City of Culture competition in Santiago de Compostela and for the extension to the Nelson-Atkins Museum in Kansas. Annette Gigon (1959) and Mark Guyer (1958) have been architects for the ETH in Zürich since 1984. Before linking up and mounting their own office in Zürich in 1980, A. Gigon was employed by Herzog & De Meuron (1985-1988), while M. Guyer worked in the office of Rem Koolhaas (1984-1987) and then as assistant to Hans Kollhoff in the ETHZ (1987-1988).
