The design transforms the three-floor Taipei headquarters of the Taiwan External Trade Development Council into an agile, human-centric corporate landmark. Successfully navigating public procurement limits and low-bid tendering conditions, the project pairs rigorous cost-efficiency with high-performance geometry mapped precisely to departmental functions. Moving vertically through thematic layers of "The River", "The Mountain", and "The Space", the layout replaces institutional monotony with fluid collaborative hubs, administrative wellness strongholds, and futuristic war rooms, establishing an international paradigm for public sector environments.
