At Japan Home Show & Building Show 2025, one of Japan's largest architectural displays, we created displays booth to promote the new product "PANECO®," an environmentally friendly material made from upcycled discarded clothing. We were responsible for the entire booth, from concept concept design to construction. Based on PANECO® and lightweight steel (LGS), we concept design a large, approximately 4-meter-tall structure with floors, walls, and ceilings entirely made of PANECO®. The full-scale walls intuitively convey the scale of PANECO®'s use as an interiors building material, while the interior proposes lifestyle scenes that utilize PANECO®. By creating different surfaces on the exterior and interior of displays booth, we were able to directly and impressively convey its use as both a base material and a finishing material, as well as the relationships between construction materials, its workability, and the unique texture and appearance of the material itself.
