From April 13 to October 13, the Osaka World Expo 2025 event was held on the artificial island of Yumeshima. Located in Osaka Bay, the exhibition area covers 155 hectares.

The main theme that structured the event's various participations centers on the motto "Designing the Future, Designing Our Lives of Tomorrow," and in turn encompasses three subthemes: "Saving Lives," "Inspiring Lives," and "Connecting Lives."

Expo 2025 Osaka was organized into three major areas—Pavilion World, Green World, and Water World—and saw the participation of approximately 150 countries, which presented their proposals in the space surrounded by the imposing wooden structure, The Grand Ring, designed by Japanese architect Sou Fujimoto.

At METALOCUS, we have selected 12 contributions that, by combining traditional techniques and concepts with innovative technologies, communicate new solutions that contribute to achieving the Sustainable Development Goals (SDGs).

International architectural firm Kengo Kuma and Associates, together with OMA*AMO, the think tank of the Office for Metropolitan Architecture (OMA), have developed the Qatar Pavilion for the 2025 Osaka Expo. The project is conceived as a lightweight wooden structure, clad in a gauzy white fabric, housing a multimedia exhibition exploring how the country's 563 kilometers of coastline have shaped the nation's culture, heritage, identity, and industry.

The representative essence of the Qatari people finds meaning and purpose in the shores of their coastline. In that sense, the project seeks to represent the dynamic harmony between land and sea, which has provided a livelihood that has helped transform the people of Qatar into what it is today: a global center of trade and diplomacy.

02. A pavilion that becomes a landscape. Spain Pavilion for Expo 2025 in Osaka

The Spanish Pavilion for Expo 2025 Osaka, or as its designers have described it, "the construction of a landscape," is a landscape that dialogues with the setting sun, a symbol shared by Spain and Japan. The project was carried out by the team of architectural firms Enorme Studio, Smart and Green Design, and Néstor Montenegro Mateos, grouped under Kuroshio Osaka 2025.

Expo 2025 Osaka, which has been deployed on an artificial island in Osaka Bay, occupies an area of ​​155 hectares and is organised into three main areas: Pavilion World, Green World, and Water World. Pavilion World, with an area of ​​65 hectares, is divided into three thematic zones: Saving Lives, Empowering Lives, and Connecting Lives. In this last area, located in the northern part of the "Great Ring" and dedicated to exploring human connections, is the Spanish Pavilion at the site's north end.

The pavilion is located on a plot of approximately 3,500 square meters, elongated rectangular, widening towards the main facade that faces the Grand Ring and narrowing towards the rear of the Pavilion that faces the "Forest of Tranquility", in a strategic position next to one of the main avenues of the venue and very close to the two main entrances of the event, having as neighbors pavilions such as the Kingdom of Saudi Arabia pavilion, designed by Foster + Partners.

03. Theatre of life. France Pavilion at the Osaka World Expo 2025 by Coldefy & CRA-Carlo Ratti Associati

The architectural team of Coldefy & CRA-Carlo Ratti Associati has been selected to design the French Pavilion at the 2025 Osaka World Expo.

The World Expo will be held from April 13 to October 13, 2025, on Yumeshima Island, a 155-hectare artificial island in Osaka Bay. The event's theme is "Designing the Future, Designing Our Lives of Tomorrow," structured around three subthemes: "Saving Lives," "Inspiring Lives," and "Connecting Lives."

In tune with the changing rhythms of everyday life, the Pavilion presents itself as a "theater of life," where visitors are guided through a fluid sequence of spaces that allude to the beginning, transition, pause, and departure of life itself. In the age of technology, where digital isolation prevails, the project invites people to meet and connect.

Situated in the “Empowering Lives” zone, the pavilion spans 995 square meters and rises from 13 to 17 meters in height, across four levels, overlooking the seafront.

A pavilion that brings together sustainability, heritage, and craftsmanship—celebrating Bahrain’s deep connection to the sea, it is inspired by the traditional dhow. "Built from around 3,000 pieces of unengineered wood using intricate joinery, it minimises waste,” says Ghotmeh. With natural ventilation and full material reusability, it’s designed with the future in mind.

As part of the Osaka World Expo 2025, held on Yumeshima Island from April 13 to October 13, 2025, the OMA/AMO team curated and designed "From the Coast, We Progress," an immersive experience that can be visited within the Qatar Pavilion, developed by Japanese studio Kengo Kuma & Associates. The project is one of the latest projects in OMA's growing portfolio in the Gulf region, having completed projects such as the Qatar National Library and the Qatar Foundation Headquarters, both completed in 2017.

The exhibition's vision is based on highlighting the importance of the Qatari coastline in the nation's development and economic growth. A compact peninsula encompassing twelve key coastal enclaves, Qatar has developed its industries along its waterfront for centuries, reflecting its close and historic relationship with its coastline. Offering a visual and experimental narrative, the exhibition integrates concepts such as culture, identity, and environment.

Applying architectural thinking to domains beyond building, AMO has worked with Prada, the European Union, Universal Studios, Amsterdam’s Schiphol airport, Condé Nast, Harvard University, and the Hermitage. It has produced exhibitions, including Expansion and Neglect (2005) and When Attitudes Become Form: Bern 1969/Venice 2013 (2013) at the Venice Biennale; The Gulf (2006), Cronocaos (2010), Public Works (2012), and Elements of Architecture (2014) at the Venice Architecture Biennale; and Serial Classics and Portable Classics (both 2015) at Fondazione Prada, Milan and Venice, respectively.

AMO often works in parallel with OMA's clients to fertilize architecture with intelligence from this array of disciplines. This is the case with Prada: AMO's research into identity, in-store technology, and new possibilities of content-production in fashion helped generate OMA's architectural designs for new Prada epicenter stores in New York and Los Angeles. In 2004, AMO was commissioned by the European Union to study its visual communication, and designed a coloured "barcode" flag – combining the flags of all member states – that was used during the Austrian presidency of the EU.

AMO has worked with Universal Studios, Amsterdam's Schiphol airport, Heineken, Ikea, Condé Nast, Harvard University and the Hermitage. It has produced exhibitions at the Venice Architecture Biennale, including The Gulf (2006), Cronocaos (2010) and Public Works (2012) and for Fondazione Prada including When Attitudes Become Form (2012) and Serial and Portable Classics (2015). AMO, with Harvard University, was responsible for the research and curation of the 14th Venice Architecture Biennale and its principle publication Elements. Other notable projects are a plan for a Europe-wide renewable energy grid; Project Japan, a 720-page book on the Metabolism architecture movement (Taschen, 2010); and the educational program of Strelka Institute in Moscow.

ENORME Studio, founded in Madrid in 2016, is the evolution of three co-founders of PKMN Architectures: Carmelo Rodríguez, Rocío Pina and David Pérez. After collaborating for ten years on more than a hundred projects, they have launched this new shared initiative that maintains the same radical approach to architecture. They design and build architectural projects based on industrial systems and typological innovation.

They specialize in the design of mobile systems applied to housing, workspace, and commerce. They have transformed the traditional concept of living into architecture, creating spaces that are easily transformed through simple gestures. They design and implement participatory dynamics in the field of city construction through their creative services platform CIUDAD CREA CIUDAD and the creation of CITIZEN BRAND IDENTITIES. Their goal is to promote alternative ways of addressing urban issues and motivate the creation of a proactive civic culture. They design and apply "Tactical Urbanism" tools that translate teamwork strategies and collective thinking dynamics into the design and management of public and private spaces. Their goal is to return the city to its citizens as an emotional, plural, and relational space.

Among their most notable projects is their collaboration on the Spanish Pavilion for Expo 2025 Osaka, alongside Néstor Montenegro and Smart and Green Design. Selected through a public competition organized by Acción Cultural Española, their proposal, under the motto "The Kuroshio Current," seeks to connect Spain and Japan through a comprehensive experience that combines architecture, art, design, gastronomy, and outreach, using sustainable and low-impact materials.

Other recent projects include the flexible Beyome home in Madrid, a modular system that allows rooms to be reconfigured according to the needs of the inhabitants, and the installation The Theory of Cherries, a playful and colorful proposal that encourages interaction and reflection on public spaces.

ENORME Studio has been recognized for its innovation and commitment to sustainability, participating in various competitions and receiving mentions in specialized publications. Its interdisciplinary and participatory approach continues to position it as a benchmark in contemporary Spanish architecture.

Shigeru Ban was born in Tokyo in 1957 and after studying architecture in Los Angeles and New York, he opened an architectural practice in Tokyo, in 1985, with offices in Paris and New York, and has designed projects worldwide from private houses to large-scale museums.

His cardboard tube structures have aroused enormous interest. As long ago as 1986, he discovered the benefits of this recyclable and resilient material that is also easy to process. Shigeru Ban built the Japanese pavilion for the Expo 2000 world exposition at Hanover – a structure made of cardboard tubes that measured 75 meters in length and 15 meters in height. All the materials used in the structure were recycled after the exhibition. He developed a genuine style of "emergency architecture" as a response to the population explosion and natural disasters: the foundations of his low-cost houses are made of beer crates filled with sand, and the walls consist of foil-covered cardboard tubes. A house of this sort can be erected in less than seven hours and is considerably more sturdy than a tent.

Shigeru Ban is currently a Professor of Architecture at Keio University and is also a guest lecturer at various other universities across the globe; his works are so exceptional that he was awarded the Thomas Jefferson Foundation Medal in Architecture in 2005. "Time" magazine describes him as one of the key innovators of the 21st century in the field of architecture and design.

Shigeru Ban has designed projects such as Centre Pompidou Metz and Nine Bridges Golf Clubhouse in Korea. Current projects include new headquarters for Swatch and Omega in Switzerland.

Komy Studio is a versatile architectural firm founded by Masafumi Yukimoto in 2021 with offices in Takasaki and Tokyo, Japan.

The firm primarily focuses on architecture and interior design projects, but is also actively involved in urban and architectural planning and design, construction supervision, consulting, research and analysis of urban and architectural conditions, furniture, textiles, lighting, renderings, illustrations, window displays, and writing and translation.

Masafumi Yukimoto, the studio's founder, graduated from the Tyler School of Art at Temple University in Philadelphia (USA) in 1998. In 2008, he earned a Master of Architecture from the Cranbrook Academy of Art. He subsequently worked at Shigeru Ban Architect (Tokyo) until 2011, when he joined Kengo Kuma and Associates (Tokyo). In 2021, he founded Komy Studio (with offices in Takasaki and Tokyo, Japan), which remains active to this day.

Komy Studio's vision is to offer people never-before-seen "scenarios." Design involves creating forms through a complex process of selecting and coordinating various conditions. Its goal is to transcend this complexity to create forms and spaces with the essential meaning of place and material. Through this process, people open up to new experiences and discover "scenarios" they have longed to see. This gives rise to the vision of a new society.

Norman Foster is considered by many to be the most prominent architect in Britain. He won the 1999 Pritzker Architecture Prize and the 2009 Príncipe de Asturias de las Artes Prize.

Lord Foster rebuilt the Reichstag as a new German Parliament in Berlin and designed a contemporary Great Court for the British Museum. He linked St. Paul's Cathedral to the Tate Modern with the Millennium Bridge, a steel footbridge across the Thames. He designed the Hearst Corporation Building in Manhattan, at 57th Street and Eighth Avenue.

He was born in Manchester, England, in 1935. Among his firm’s many other projects are London’s City Hall, the Bilbao Metro in Spain, the Canary Wharf Underground Station in London and the renovated courtyard of the Smithsonian American Art Museum and National Portrait Gallery in Washington.

In the 1970s, Lord Foster was one of the most visible practitioners of high-tech architecture that fetishized machine culture. His triumphant 1986 Hong Kong and Shanghai bank building, conceived as a kit-of-parts plugged into a towering steel frame, was capitalism's answer to the populist Pompidou Center in Paris.

Nicolai Ouroussoff, The Times’s architecture critic, has written that although Lord Foster’s work has become sleeker and more predictable in recent years, his forms are always driven by an internal structural logic, and they treat their surroundings with a refreshing bluntness.

Awarded the Prince of Asturias of the Arts 2009.
