Manuel Herz Architects have designed the Swiss Pavilion for Expo 2025 in Osaka, focusing on Switzerland’s nature and humanistic traditions. The pavilion features a cluster of plastic-based spheres that seamlessly integrate nature and culture. The structure appears to grow out of and be surrounded by greenery. This innovative design aims to minimise its environmental footprint, making it the smallest and lightest Swiss pavilion to date.

The exhibition area consists of a double-chamber foil supported at ground level, eliminating the need for lifts or escalators. The spheres are covered with locally grown plants, the weight of each plant corresponding to the removal of CO2 from the atmosphere. The back-of-house of the pavilion is made of reused modular elements, ensuring a life after the Expo. The structure is based on a recyclable ETFE pneumatic envelope supported by a steel framework, allowing for a compressed air system without airlocks.

The scenography by Bellprat Partner makes use of light and colour to create an immersive and continuous narrative throughout the entire pavilion. Visitors can explore the “Spheres of Swiss Innovation”, participate in the creation of a Future Society and enjoy panoramic views from the rooftop bar. This pavilion will not only showcase Swiss innovation, but also provide a sustainable and engaging experience.
