Temporary Action for Long-term Change: Urban Regeneration Strategies from the Perspective of Interim Use

In China, urban construction has entered the stage of stock regeneration, and the development of traditional urban regeneration is facing more challenges and difficulties. Interim use is considered as a tool to solve the traditional problems of regeneration, promote the revitalization of the old city, and trigger the vitality of the community. It has become a research hotspot to integrate interim use with the overall goals and formal planning system of urban development and make it a catalyst for sustainable development. This study aims at exploring the phenomena of interim use and its role in promoting urban regeneration, summarizing the urban design theories and strategies derived from interim use, and providing an innovative idea for solving problems about urban regeneration. This thesis firstly sorts out the concept, theory and development stage of interim use, and sums up three application modes of interim use in urban regeneration practice about informal interim use legalization and formal interim use. Aiming at these three application modes, this thesis deeply analyses two typical cases of interim use in urban renewal, extracts the methods and strategies of interim use in urban renewal system from three aspects of legal policy, organizational structure and business model, and analyses the Impact of interim use on subsequent planning. Based on the above theoretical research and case analysis, this thesis initially constructs the workflow and interim design strategies. Finally, this paper combines the workflow and strategy with the current situation of urban renewal in Guangzhou, selects a historical residential block in Guangzhou as the application object, solves the renewal problems encountered in the actual site, and obtains interim use guidelines and a long-term renewal plan. This study illustrates the application scenarios of interim use in formal planning systems, mainly top-down redevelopment of key areas and bottom-up community renewal. Interim use in urban regeneration essentially acts as a complementary tool to formal planning, providing a bottom-up policy platform and potential solutions. Therefore, the interim use theory can supplement the construction of an urban regeneration system from three aspects: dynamic planning, public participation and intervention methods. In addition, interim use provides new ideas for urban regeneration design methods. On the one hand, the interim design strategy can utilize the transition period before the formal project is implemented to put temporary use into effect, and gradually realize the transformation of the area. On the other hand, interim use can make use of the remaining space to enhance the physical environment by producing new public spaces, at the same time relying on public participation to boost community cohesion to achieve urban regeneration on a social and physical level. The strategy based on interim use expands the static planning into sustainable public participation, and provides a reference for spurring the innovation of our country's urban regeneration system, policy improvement and spatial strategy.
