The aim of this thesis is to make redesign strategy for the improvement of Nanjing “Window on the World” Creative Industries Park, following the principles of the Organic Update Concept, and that makes full use of brownfields itself favorable conditions to create a lively district that integrate into the surroundings. The Research Question is how can the Organic Update Concept be used to improve the transformation of the brownfields in Qinhuai District, Nanjing? In order to answer this question, the following two sub-questions are addressed: What working principles of Organic Update can be concluded from the literature of Organic Update Concept? How can the strategies found in literature and tested in the cases be adapted to the local context of Qinhuai District? By studying Organic Update Concept, I understand a concept that focus on respecting the local history and culture, also the current situation to make a long-term plan, but start with small-scale. It seems to make Sustainable Development Concept in detail and put into practice. Moreover, the concept is more applicable to the area with a certain cultural and historical background. Apart from keeping continuity of the history, it emphasis to make the area integrate into a big environment. According to the literature review, I sum up the working principles, namely, integrity, continuity, multi-function, identifiability and small-scale gradual mode and test them in the cases, and apply in my design proposal. The main finds of this thesis prove that Organic Update Concept can be regard as a planning tool, not only used to update and develop the historic district of the city, but also can be used to transform and improve the brownfields, even for planning a city. According to the “OUC” working principles, I make a design proposal for the improvement of Nanjing “Window on the World” Creative Industries Park.
