Plastics are high-performance materials of wide use in the built environment. Their versatile technical properties are particularly fascinating. A broad range of form-giving and finishing processes makes plastic especially interesting for complex geometries in combination with digital planning processes. Following the pioneering plastic structures of the 1970s, a number of spectacular buildings have in recent years highlighted the outstanding technical and aesthetic potential of the material. Until now, however, there has been no systematic treatment of the use of plastic in architecture. This book seeks to fill that gap by providing an introduction to the structural and design possibilities of plastic. It introduces the material and its specific characteristics, describes various types of plastic in terms of their relevance for building, explains processing technologies and presents typical products and components. A concise presentation of twenty-five international built projects – organized by the type of application and the plastic involved – documents the broad range of plastic in architecture. Finally, a look ahead at the future describes the current state of the art in materials research.
