An Inquiry into the Preservation and Renewal of Historic District, Grounded Within the Theoretical Framework of Catalyst Theory ——With a Case Study of Panxi Restaurant

The philosophical approach to urban design in China has been converted from new-built to re-built. Historic districts are hence leading to a heightened appreciation and delicate handling. WU Liangyong, a prominent Chinese academician, has concluded that plans for historic districts should be implemented with gradualness and carefulness, forming the cornerstone of the Organic Renewal Theory. On the other hand, the Catalysts Theory, an urban design theory originated from the progress of American reconstruction, offers an elastic design framework for our ongoing research. From this line of works, the Organic Renewal Theory could be advised in at least two lenses: its systematic perspective and its practical feasibility. Furthermore, the Catalyst Theory could introduce a potential for a chain reaction, facilitating the progress while safeguarding the integrity of authentic lifestyle. To illustrate how the Catalyst Theory guides practical application, this article examines an ongoing project in Guangzhou as a case study, showcasing its implementation and establishing a framework adaptable to the designs of nearby neighborhoods.
