The Research of Co-design Approaches Based on Designer Guidance in the Renovation of Old Community in Shanghai- Illustrated in the Case of Zhuyuan Community Center

With the decrease in usable land in recent years, people have begun to pay more attention to the renovation of small and micro space in old community space and discussion on urban space have gradually shifted from spatial to social attributes and social meanings. The demonstration of public participation process has been exactly being of significance on urban updating and adaptive reusing of existing stocks. Simultaneously, it has caused rethink about conventional designer-leading projects and enlightened academics about bottom-up concept for renovation. Nevertheless, the existing approaches of public participation is still facing certain issues such as imperfect participation mechanism, unclear-defined authorities and responsibilities, halfway involvement and so on. Through analyzing the renovation progress of the public space of Zhuyuan community, this article is aimed to argue whether the public might continuously and authentically participate to the holistic processes from preliminary design to construction and final operation based on multi-collaborations. And modular design approaches are experimented in order to integrate the variable resources, optimize the spatial functions and provide the ease of construction and assembly. Eventually, the public participation principles and strategies based on the guidance of designers are posed, which might provide a reference for the follow-up researches.
