Rising from Yumeshima —the “Island of Dreams” in Osaka Bay— the pavilion emerges as a luminous landmark, clad in a skin of pentagonal modules that repeat in rhythmic harmony. Its structure, conceived in timber, not only ensures sustainability but also resonates with the Japanese tradition of building in close dialogue with nature.
Pedras’s design is a geometric wooden landscape that invites visitors to rediscover their bond with the natural world at Expo 2025 Osaka. More than a building, it is an ecological manifesto: a structure that mirrors the intelligence of nature while shaping new possibilities for encounter and reflection within a Sakura-inspired sanctuary.

“Biomateriality and textures that bridge disciplines, where the variety of grains and pleated surfaces generate distinctive identities.”

During the development phase, the discovery of a highly versatile module proved essential, not only reducing design costs but also enabling limitless adaptability. Structures of different shapes and scales can be created without the need to start from scratch, as all possible configurations emerge from this single system. The pavilion can be dismantled and reassembled for new uses, maintaining its integrity whether preserved in its original form or transformed into new ones.
The elements and materials are conceived for circularity: they can be easily recovered, reused, and recycled without generating further pollution —a fundamental prerogative of sustainable architecture. Each component is designed for assembly and subsequent disassembly, ensuring a responsible life cycle.
The main entrance is located on the northern side of the Pavilion World, within the “Connecting Lives” thematic area. Here, the values of unpredictability, self-sufficiency, and continuous growth —qualities inherent in living systems and nature— acquire architectural expression. This approach redefines how we conceive and construct our urban environments, fostering a more respectful and equitable dialogue between humanity and nature, and laying the foundation for a profound shift in the way we inhabit the world.
