Our built environment is the result of multilayered and elaborate thought and design processes. Each of the architecture, landscape architecture, and civil engineering disciplines involved in this process has a wide range of design methods and their own disciplinary culture and history of ideas. New methodological approaches have emerged at the interfaces of these disciplines that require an interdisciplinary debate about designing. The focus of this publication is the current discussion about design, understood not only as the creation of a beautiful product, but as a task of building culture. This book provides new insights and perspectives and illuminates the array of methodological approaches and design options called for by our built environment?from the design to the realization and the finished property.
