Illustrated by critical analyses of significant buildings, including examples by such eminent architects as Adler and Sullivan, Erich Mendelsohn, and Louis Kahn, this book examines collaboration in the architectural design process over a period ranging from the mid-19th century to the late 1960s. The examples chosen, located in England, the United States, Israel and South Africa, are of international scope. They have intrinsic interest as works of architecture, and illustrate all facets of collaboration, involving architects, engineers and clients. Prior to dealing with the case studies the theoretical framework is set in three introductory essays which discuss in general terms the organizational implications of partnerships, associations and teams; the nature of interactions between architect and engineer; and cooperation and confrontation in the relationship between architect and client. From this original standpoint, the interactive role of the designers, it examines and reinterprets such well-known buildings as the Chicago Auditorium and the Kimbell Art Museum. The re-evaluation of St Pancras Station and its hotel questions common presumptions about the separation of professional roles played by its engineer and architect. The account of the troubled history of Mendelsohn’s project for the first Haifa Power House highlights the difficulties that arise when a determined and eminent architect confronts a powerful and demanding client. In a later era, the examination of the John Moffat Building, which is less well known but deserving of wider recognition, reveals how the fruitful collaboration of multiple architects can result in a successful unified design. These case studies comprise a wide range of programmes, challenges, personalities and interactions. Ultimately, in five different ways, in five different epochs, and in five different circumstantial and cultural contexts, this book shows how the dialogue between the players in the design process resonates upon the works of architecture that their collaboration engenders.
