This studio explored the potential of lightweight timber structures for Expo 2025 in Osaka, Japan, focusing on large-scale cellular pavilions that maximize structural efficiency while minimizing material use. Through an integration of 3D graphic statics as a geometry-based form finding technique, we were able to create highly performative and architecturally expressive pavilion designs.
The project, located in the "Saving Lives" zone of the expo, explores the theme of protecting life through harmony and coexistence between people and nature. Drawing from Kengo Kuma's Makeru-Architecture, which emphasizes withing with rather than against the environment, the pavilion integrates organically with its surroundings reflecting a sustainable and respectful design approach. To further promote this idea through materiality, wood is the primary material with steel used secondarily only at the joints. The use of wood aligned with Japan's sustainable construction goals, emphasizing low-carbon, renewable materials that can be sourced and reassembled efficiently.
Inspired by the Tokiyo structural system and the nearby "Forest of Tranquility," the space emulates a forest canopy, offering a sensory experience akin to Komorebi, a term for sunlight filtering through leaves, encouraging natural ventilation and light throughout the entire pavilion and open spaces. In taking inspiration from natural elements to embody the forest canopy of our structure, the 3D graphic statics originally took the form of a butterfly. This structural module was repeated and transformed along with tree-like structures forming the final structural form.
Spaces within our forest range from open and inviting exhibit spaces to smaller and more intimate study pod and conversation spaces.
