The Eco Hanok, located in Dongmyeong-dong, Gwangju, originated as an urban hanok that had been left abandoned for some time. It now serves as a symbolic stage for addressing global issues of climate change and resource circulation through practical reinventions within the contemporary challenges of urban decline and regeneration. As both an experimental and distinctly architectural act, Eco Hanok has become an integral element within the urban fabric of Dongmyeong-dong and Gwangju. Thus, the before-and-after context of Eco Hanok holds significant implications as part of architectural intervention and urban evolution. Throughout the process, TechCapsule documented three key stages—original hanok, repurposed timber structure, and the final completion using new materials—by capturing 3D scans. As completion marks the beginning of an ongoing evolution, this digital archive of the past is anticipated to act as a lens that reflects the value of the present and future.
