Shigeru Ban's Blue Ocean Dome pavilion for Expo 2025 Osaka showcases his commitment to sustainable architecture using innovative materials such as laminated bamboo and carbon-fibre reinforced plastic. Commissioned by Zero Emissions Research and Initiatives (ZERI), the pavilion features a central dome flanked by two smaller domes, all built to highlight ocean conservation. Designed to be lightweight and easily disassembled, the structure minimizes waste post-event and serves as a platform for environmental awareness. Ban's creative use of materials adheres to strict building regulations while promoting reusability.
In countries that have very strong building regulations, we cannot use natural bamboo as a building material, including in Japan. However, if we laminate the bamboo, we can control the quality, strength, and durability. So in the pavilion, I'm using laminated bamboo as a structure in a very unusual way.
The pavilion design highlights sustainable building materials and serves as a platform for raising awareness about ocean conservation and environmental responsibility.
The entrance, Dome A, is constructed from laminated bamboo, chosen over natural bamboo to comply with Japanese building regulations.
Ban selected carbon-fibre reinforced plastic tubes for the central dome to eliminate the need for concrete piles in the foundation, showcasing innovation in sustainable architecture.
