In the course of the past several years, KSP Engel and Zimmermann have joined the ranks of the most successful architectural firms in Germany. The architects now maintain offices in Berlin, Braunschweig, Frankfurt, Cologne, and Munich. Their projects include office buildings, hospitals, schools, libraries, sports facilities, and residential architecture. Their rich architectural language covers a broad spectrum--from sensitive intervention in existing structures to striking high-rise buildings. This publication features an interview in which the two architects offer insights into their approach to architecture, their curiosity about building abroad, and their recent success. Essays by Peter Davey, editor-in-chief of Architectural Review, and Ingeborg Flagge, director of the Deutsches Architektur Museum, provide a portrait of these self-assured yet open-minded and highly pragmatic architects. The book illustrates the firm's architectural and planning competence in a presentation of 40 different projects, including the Federal Press Office in Berlin, the Trade Fair Forum in Frankfurt, the Volkswagen Hall in Braunschweig, the Bertelsmann Foundation building in Gtersloh, and a number of high-rise projects in Frankfurt.
