Spanish Pavilion Expo 2025 in Osaka: Sustainable Circular Architecture by ENORME Studio, EXTUDIO, and Smart and Green Design

A Pavilion that Blends Innovation, Culture, and Sustainability

The Spanish Pavilion Expo 2025 in Osaka stands as a bold architectural statement designed by ENORME Studio, EXTUDIO, and Smart and Green Design. Covering 3,500 m², the pavilion celebrates Spain’s culture, innovation, and sustainable future while serving as a strategic platform for international dialogue.

Over six months, it will host companies, regional institutions, and cultural organizations, transforming architecture into a powerful tool for visibility and exchange on a global stage.

Conceptual Roots: Between Spain and Japan

The pavilion’s design establishes a symbolic connection between Spain and Japan, rooted in the 16th-century maritime route created by Basque navigator Andrés de Urdaneta. The theme is further reinforced by the sun—an emblem central to both cultures—that becomes the guiding motif of the architectural and exhibition journey.

The pavilion acts as both a cultural bridge and a welcoming open landscape, offering visitors an immersive experience shaped by history, identity, and shared global values.

A Mediterranean Plaza Experience

Unlike other monumental Expo pavilions, the Spanish Pavilion Expo 2025 in Osaka proposes an accessible, open structure inspired by Mediterranean public squares. Visitors enter through a vast plaza that encourages interaction, play, and rest.

At its heart lies the Plaza del Sol, featuring a dynamic LED façade showcasing video art on the symbolism of the sun. The journey continues along a descending ramp that evokes a dive into the ocean, immersing visitors in ultramarine tones before reemerging into vibrant, light-filled spaces that capture Spain’s festive and creative spirit.

Circular Design and Zero Legacy

One of the most innovative aspects of the pavilion is its circular architectural approach. Since Expo 2025 in Osaka will dismantle all pavilions after the event, the Spanish Pavilion has been designed for disassembly and reuse. Every component has a planned second life—either reconstructed elsewhere or reintegrated into production chains.

Natural, locally sourced Japanese red cedar forms the main portico structure, assembled with dry joints for easy disassembly. This repetition of wooden double pillars and T-shaped beams shapes the interiors while minimizing the environmental footprint. The pavilion embodies a near-zero impact design philosophy.

Sustainable Materials and Collaborations

The project emphasizes ecological responsibility by collaborating with expert artisans and sustainable manufacturers. Ceràmica Cumella provided colorful façade ceramics, while Ondarreta contributed furniture crafted from certified wood and recycled textiles.

Partition panels made from recycled paper by Honext and interior finishes derived from ocean-recovered plastics by Gravity Waves further illustrate the pavilion’s commitment to sustainable innovation. Supported by waste management specialists such as CoCircular, the pavilion achieves a holistic circularity aligned with Expo 2025’s environmental goals.

An Immersive Visitor Journey

The pavilion’s narrative unfolds in four stages:

• The Plaza of the Sun introduces Spanish culture through live performances and audiovisual art.
• Currents Towards the Future immerses visitors in an ocean-inspired journey that highlights the blue economy and Spain’s maritime heritage.
• Greetings from Spain celebrates Spanish creativity and festivity with an interactive audiovisual installation.
• A Diverse Spain showcases the cultural richness of Spain’s 17 autonomous communities through a multimedia screen leading to the final spaces—shop, seafood restaurant, and multipurpose rooms.

This progression blends architecture, storytelling, and sensory immersion, leaving visitors with a powerful impression of Spain’s cultural depth and sustainability-driven vision.

A Model for Future Pavilions

The Spanish Pavilion Expo 2025 in Osaka is more than an exhibition space—it is a prototype for sustainable circular architecture. By integrating cultural symbolism, ecological materials, and flexible construction, it exemplifies how world expos can transition towards more responsible and meaningful architecture.
