Abstract

In contemporary urban design, co-creation has become increasingly relevant as an approach to address complex social, spatial, and governance-related challenges. This study develops an empirically informed framework for structuring co-creation processes in urban design, based on theme-centered interaction (TCI). Drawing on qualitative case study material, this study translates key relational, procedural, and contextual dynamics of co-creation into a structured set of guiding principles that address individual perspectives, group dynamics, task-oriented challenges, and broader contextual conditions. The framework offers analytically grounded guidance to support reflective, process-oriented co-creation in urban design. In addition, the study introduces steward ownership as a novel interpretative governance perspective that helps contextualize and stabilize co-creative outcomes beyond the design phase. Steward ownership is presented as a conceptual governance perspective, rather than an empirical finding, that aligns with values of shared responsibility, long-term orientation, and collective stewardship. By linking empirical insights with TCI-based process structuring and governance considerations, this study contributes to ongoing debates on how co-creation in urban design can be more systematically organized and institutionally sustained in practice.
