This volume is a complete monograph on the work of German architect Hans Kollhoff (b. 1946) and his partner, Helga Timmerman (b. 1953), with whom he has collaborated since 1984. It presents 100 buildings and projects completed by Kollhoff and his firm since the 1970s, beginning with his Project for an Analogous City of 1976 and including competitions, office and multiuse buildings, banks, apartment complexes, and urban planning. Kollhoff began his teaching and investigations into the city during the postmodern debates of the 1970s, when he studied with O.M. Ungers at Cornell University. Since that time he has focused on large-scale architecture and its role in preserving the urban landscape, striving to discover the essence in traditional architecture, and to build a new tradition from it. Jasper Cepl introduces this book with an investigative essay examining Kollhoff's career and theoretical direction since the late 1960s. Following the introduction are 100 projects presented chronologically, including recent work in Berlin, such as the DaimlerChrysler Highrise Building (2000), the Extension of the Pergamon Museum (2000), and the renovation of the Former Seat of the Reichsbank for the Ministry of Foreign Affairs (1999).
