As one of the signature pavilions at Expo 2025 Osaka, the ‘null²’ Pavilion showcases innovative design and technology. The design concept is based on the motif of a mirror, inviting guests to reflect on their own existence in both the real and virtual worlds. It aims to create an unseen landscape.
To realise this vision, we worked with the pavilion’s producer and media artist Yoichi Ochiai and NOIZ, utilising cutting-edge digital technology to delve into next-generation design and societal values. A distinctive mirrored exterior material was developed with Taiyo Kogyo Corporation through iterative prototyping, culminating in a dynamic, reflective architectural membrane.
The pavilion features a main building with exhibition rooms and steel-framed cubes called ‘Voxels’ – 3D visual elements suspended around the structure. These shift in appearance with the viewer’s angle. A robotic arm and woofer on the Voxel’s reverse side generate localised vibrations and movements in the mirrored landscape.
We provided overall engineering support, including structural design, environmental facility design, membrane development consulting and geometry.
Our integrated engineering approach enabled the creation of a pioneering pavilion that fuses art, architecture and emerging technology. The result is a structurally and conceptually innovative experience that expands architectural possibilities and exemplifies future-forward, sustainable design thinking.
