This book aims to challenge the pervasive urban planning masterplanning concepts and methodologies which aim to project the final state of the city. In a context in which never before has so much urbanization occurred as in the last twenty years in China, cities are growing and changing so quickly, I am championing an evolutionary approach to urbanization. What is interesting at this stage is we have computational tools to not only design formal differentiations and specificities, but also to develop the capacity to manage and to control change without determining its final state. This thesis assumes all cities are not finite but rather that they are always in transition. The city offers a whole new level of complexity to harness and manage, but not to overdetermine.
