The standard work on Heino Engel's structure systems is now available at an attractive price. On the basis of excellent drawings and model photographs, the book examines the various forms of structure systems and explores the relationship between structure system and architectural form in clear and concise prose. In the presentation and explanation of this highly complex discipline, this volume differs fundamentally from other publications on the subject, as the author focuses entirely upon structure systems without regard for the usual technical details. Featured here are typical structure systems and models in lieu of the more commonly treated special designs and completed buildings. As a reference work, the book provides an indispensable repertoire of forms for modern architectural models, summarizing traditional approaches and offering a source of new ideas at the same time.
