“Wandering Matrix” is a sustainable exhibition pavilion for O-Wood at Guangzhou Design Week, addressing waste in temporary brand displays. It translates the brand’s values of zero formaldehyde, recyclability, prefabrication, and customization into a modular spatial system. A 3×3 m grid, perforated aluminum frames, and FRP furniture provide a clear assembly and circulation, while curved SPC panels demonstrate material flexibility and expressive potential. All components support rapid installation, disassembly, and reuse, balancing branding impact with environmental responsibility.
