This study examines the renovation of the Jiaxing Sports Center as a case to explore how spatial aesthetics intervene in organizational identity construction prior to building completion and facilitate its continuous reproduction through institutionalized spatial scripts. Drawing on theories of organizational identity, organizational aesthetics, and the spatial turn, the study adopts an interpretive case study approach combined with visual narrative analysis. Design statements, renderings, and public documents are systematically coded and thematically analyzed using Braun and Clarke’s reflexive thematic analysis.The findings indicate that spatial aesthetics reproduces organizational identity through four interrelated dimensions. First, stable visual orders are constructed through form, materiality, color, and lighting. Second, functional zoning and circulation systems are reorganized around competition standards and spectator units, embedding identity in operational practices. Third, implicit normative support is provided through equipment and supporting facilities, reinforcing legitimacy and reliability. Fourth, post-event operations, green strategies, and multi-functional conversion mechanisms extend identity across temporal contexts.Furthermore, the study proposes a tripartite mechanism of symbolization, structuration, and anticipation, illustrating how spatial aesthetics contributes to symbolic construction, institutional embedding, and future-oriented governance. By extending organizational identity analysis to aesthetic–spatial–institutional mechanisms, this study highlights design texts as cognitive artifacts with institutional significance in public architecture governance. It also acknowledges limitations related to single-case generalizability and the lack of post-occupancy investigation.
