Enhancing community living environments constitutes a collective demand linked to societal progress and public interest. At present, numerous venerable urban communities established in the 20th century within China are experiencing aging and consequently necessitate landscape rejuvenation. For instance, taking Su’an New Village in Suzhou as a case study, this research applied community construction theory to synthesize strategies derived from the viewpoints of public engagement and the fi ve dimensions: people, culture, land, production, and landscape. The Su’an Garden pilot project examined the progressive renewal approach of “subject empowerment - space creation - public governance”. By employing spatial reproduction strategies, it reestablished emotional bonds among residents and their environment, among residents themselves, and between residents and society. This eff ort promotes the development of a community governance pattern characterized by co-building, co-governance, and shared benefi ts. A community renewal framework and a multi-party co-building mechanism were established, facilitating the exploration of synergistic renewal involving landscape ecology alongside social, cultural, and economic ecologies. In practice, it balanced environmental quality improvement with reshaping social relationships, deepening cultural identity, and exploring economic innovation, thereby completing the transition from spatial creation to social mechanism construction. This research, guided by community construction, systematically safeguards resident subjectivity and activates community self-governance capacity. It provides a new approach with both theoretical innovation and practical operability for landscape renewal in old urban communities during the stock era.
