Bureau de Change This wall tries to reimagine what the outsides of buildings could be like: not just a barrier or enclosure but an urban artefact that tells a story of craft, culture, and continuity. It draws inspiration from Korean hanok houses and the artisanal techniques of Jewajang (Roof Tile Making), Beonwajang (Tile Roofing), and Daemokjang (Traditional Wooden Architecture) to create a contemporary wall formed of multiple, layered elements.
