Circular Pavilion Architecture: Netherlands Pavilion at Expo 2025 Osaka by RAU Architects

A Vision of Sustainability and International Collaboration

The Netherlands Pavilion at Expo 2025 Osaka, designed by RAU Architects, exemplifies the future of circular pavilion architecture through innovation, sustainability, and historical diplomacy. Located in Japan, this striking 1,157-square-meter structure stands as a powerful symbol of global cooperation and environmental consciousness. The project is led by RAU Architects in collaboration with Dutch and Japanese partners, uniting architecture, engineering, and design in a singular vision for a circular future.

The Concept of "Common Ground"

Inspired by the shared cultural and economic history between the Netherlands and Japan, the pavilion’s theme, "Common Ground," highlights the urgency of international cooperation in the face of global challenges such as climate change and energy transition. The name draws from the Netherlands’ long history of water management and its physical geography, where vast areas lie below sea level. This necessity for collective effort has become a metaphor for humanity’s shared responsibilities, a principle embodied in the pavilion’s architectural and philosophical foundations.

Design Rooted in Circular Economy Principles

RAU Architects and the AND BV consortium have designed the pavilion with circular construction at its core. Every element has been crafted for reuse, with all materials digitally registered in Madaster, the materials passport platform that ensures transparency and lifecycle accountability. After the Expo, the entire structure is set to be dismantled and relocated, ready to serve a new function without waste—an exemplary model of adaptable architecture that challenges the linear "build-use-discard" model.

Symbolism in Architectural Expression

The architectural expression of the pavilion is both poetic and precise. A glowing central sphere—a metaphor for a man-made sun powered by renewable energy—anchors the space. This core installation is surrounded by a rectangular building with a kinetic facade made from undulating slats, evoking the flow of water and the movement of time. Measuring exactly 425 meters, these slats also symbolize 425 years of Dutch-Japanese relations, celebrating the long-standing cultural and economic exchange between the two nations.

An Immersive and Interactive Visitor Experience

Upon entering the pavilion, visitors are given a glowing orb that serves as their interactive key, connecting them to a series of exhibitions and experiences that unfold throughout the space. This includes installations on the Netherlands’ struggle with water, centuries of cooperation with Japan, and the global shift toward sustainability. The highlight of the exhibition is an AI-generated 360-degree dome film, an immersive audiovisual experience hosted within the central sphere. Visitors conclude their journey by contributing to a participatory art piece that invites reflections on a sustainable future.

Legacy Beyond the Expo

Beyond its six-month presence at the Expo, the Netherlands Pavilion exemplifies how architecture can transcend temporary function and contribute to a regenerative building culture. The structure is designed not just for presentation but for relocation and reuse, aligning with global sustainability goals and demonstrating that architecture can be both temporary and timeless when guided by circular values.
