In response to social shifts such as the evolving learning preferences of the digital generation, deepening social disparities, and the rise of new technologies, Korean educational facilities have pursued swift adaptations. Various initiatives have been advocated, including a five-year plan to enhance school facility environments, the school space innovation project, and the development of green smart future schools. A key feature of these endeavors has been the active incorporation of user-participatory design methods. By transitioning from a supplier-centric to a user-centered design approach, the intention to offer user-specific spaces within conventional school facilities has been affirmed. Consequently, this study scrutinizes the overall process of the school space improvement pre-planning program, using the Wonju Girls’ High School in Gangwon-do case as a reference point. The purpose was to identify the limitations of participants at each stage and suggest directions for improvement, thereby suggesting the direction of the school space improvement project to be continuously promoted.
