The exhibition and renovation of the former office building of the Capital Water Plant in the Republic of China have problems such as narrow space, outdated methods, information overload, and lack of experience. Based on this, under the principles of respecting history, serving users, and maintaining sustainable innovation, the new design explores the transformation strategies of architectural industrial heritage from three aspects: design iteration of exhibition environment space, historical narration, and venue regeneration. The design aims to efficiently activate the contemporary architectural cultural heritage, serve the needs of the times of current stock renewal and provide ideas and references for the implementation of similar projects.
