Herman Hertzberger (born 1932) can be counted among today's most interesting contemporary architects. With his buildings, he endeavors to offer a meaningful framework to the users, which they can "claim" as their own and finishing designing - a polyvalent and permeable form of structuralism with the intention being to stimulate participation. The present studio paperback offers a concise and complete presentation of Hertzberger's creative work for the first time. It includes all of his important buildings and projects from his first works in the 1960s to his most recent works, such as the Chasse theater in Breda.
