"Source Books in Architecture" is a new series focusing on new single works by significant architects. Sponsored by Ohio State University, the series reveals the architectural motivations and techniques behind each building. The Source Books document each work with sketches, models, renderings, working drawings, and photographs at a level of detail that allows complete and careful study of the project from its conception to the completion of design and construction--the musical score to the architect's symphony. The graphic component is accompanied by commentary from the architect and critics to further explore both the technical and cultural content of the work. "UN Studio/Erasmus Bridge" explores the eponymous Rotterdam bridge that brought UN Studio, the Dutch firm of Ben van Berkel and Caroline Bos, into the architectural spotlight. This volume features extensive photographic documentation by Hans Jurgen Commerell.
