NOIZ completed one of eight signature pavilions in the Expo 2025 Osaka, named null². The particular pavilion we designed was assigned to researcher/media artist Yoichi Ochiai, whose work relates to a hypothetical merger of the digital world and nature.
In consideration of the exhibition contents inside the pavilion, a limited budget, and the temporary quality of Expo pavilions, we proposed a building composition resembling a formation of voxels. The voxel-like cubes are related to a low-resolution method of expression in digital space, such as in games and VR space. One could imagine rearranging the voxels as if in a Minecraft world or viewing the voxels as incomplete voxel clusters that could theoretically expand. The composition also worked as practical and architectural units as 2m, 4m, and 8m cubes, encapsulating four functional areas: Exhibition Hall, Security Station, Back-Office, and Rest Area. These simple and highly flexible components, made from steel frames and mirrored membranes, allowed for adaptability to budget and functional changes. They also supported disassembly, potential relocation, and alteration after the Expo.
The exterior wall resembled mirrors that unexpectedly vibrated with the wind and changed visually with the movement of the sun, as if on an ever-changing rhythm. While they appeared to be stainless steel panels, the material is actually a 98% reflective membrane that we co-developed with Japanese tent manufacturer Taiyo Kogyo and the production team of the pavilion. Additionally, woofers and robotic arms installed in some cubes create low-frequency vibrations and robotic movements according to programs. These effects of distortion, reflection, and overlapping of the scene make the vision as if many parallel worlds intersected and enhanced the pavilion's appearance as a virtual entity that came alive in reality.
