This study focuses on the historical townscape preservation project Residence and Reborn in Kaohsiung, Taiwan, and aims to clarify planning methods that simultaneously promote townscape preservation and the continuous mobilization and settlement of everyday activities. The findings indicate that, in historical townscape preservation efforts that involve attracting independent participants, planning methods need to be constructed through a dual approach: intervention, in which planners actively engage in preservation, and non-intervention, which allows participants freedom in their activities. Furthermore, to advance area-wide townscape preservation, it is suggested that the preservation area can be expanded while maintaining continuity by strategically arranging different types of activities—such as the expansion of preserved areas and the inheritance of preserved houses—based on past programs and participant activities.
