Julie Yu-Joun Kim and co-editor Stephen Vogel review and summarize the content of the ten contributed chapters and the lessons learned through the work of the authors. The conclusion also illustrates how the terrain vague concept of Ignasí de Solà-Morales applies to the work presented in this edited volume and suggests how these lessons might be applied by government, universities, and communities in other post-industrial cities with similar issues facing Detroit. The co-authors summarize valuable lessons that architects, urban designers, and artists can import into their respective design thinking processes to yield thoughtful and appropriate solutions, ones that build upon the tradition of a place but simultaneously look to the future with an optimism and inventiveness. A central point of the conclusion is that the design-thinking process is not solely about urban design nor is it solely about architecture nor is it solely about art. It is about architecture, urban design, and art as one.
