In a shifting societal and environmental landscape, how can architectural design respond to transformation while meaningfully engaging with what endures? 1110 Office for Architecture, based in Osaka, Japan, approaches this question through a body of work defined by careful residential renovations and precise spatial interventions.
Named a winner of the ArchDaily 2025 Next Practices Awards, the practice represents an emerging voice in redefining architecture's role within conditions of change.
The 2025 Osaka Expo has captured widespread attention—not only for its architectural ambition and spectacle, but also for breaking records and generating controversy. Its most iconic feature, a monumental timber ring designed by Sou Fujimoto, has already made headlines as a Guinness World Record-breaking wooden structure. Built on the reclaimed island of Yumeshima, the site has attracted praise and critique in equal measure. Beyond its awe-inspiring 2-kilometer circumference—parts of which extend dramatically over the water—the structure has also drawn concerns, including questions about health & safety, extreme heat, and swarms of insects that may affect the visitor experience.
This year also marks a significant anniversary: the 55th year since the 1970 Osaka Expo, held under drastically different socio-economic conditions. Comparing these two expos—both hosted in the same city—offers a rare opportunity to reflect on how the rhetoric, curatorial themes, and architectural ambitions of world expos have evolved over time. From "Progress and Harmony for Mankind" in 1970 to "Designing Future Society for Our Lives" in 2025, the shift in thematic focus reveals changing global priorities. Meanwhile, the scale and nature of architectural involvement have also transformed, from the futuristic visions of Japanese Metabolism to a more internationally dispersed group of designers concerned with sustainability, technology, and civic engagement.
Taschen's new book, published in October 2025, Tadao Ando. Sketches, Drawings, and Architecture presents an in-depth exploration of the Japanese architect Tadao Ando's creative process, bringing together over 750 sketches, drawings, models, and technical plans developed over nearly five decades. Created in close collaboration with Ando himself, the book provides a rare view into how his ideas take shape, from the immediacy of the first pencil lines to the precision of architectural drawings that define his built works. Through these materials, the publication highlights Ando's enduring focus on the relationship between hand, thought, and space.
About a month after the closing of Expo 2025 Osaka, the designs and constructions presented at the world's fair remain as a legacy. While the Bahrain Pavilion, designed by Lina Ghotmeh Architecture, drew particular attention this year for receiving double recognition, it was one among many awarded projects. During the awards ceremony held on the penultimate night of the event, a total of 45 awards were presented among 165 participating countries. The Official Participant Awards are granted according to pavilion size and type, recognizing excellence in Architecture and Landscape (for self-built pavilions only), External Design (for module pavilions only), Exhibition Design, Theme Development, and Sustainability. The recipients were selected by an international jury of nine experts who visited all national and thematic pavilions during two evaluation sessions in May and October 2025. The following overview presents all 45 pavilions distinguished in the five categories of the Official Participant Awards.
Monday, October 13th, marked the conclusion of Expo Osaka 2025. The exhibition gathered representatives from 165 countries and international organizations and welcomed around 28 million visitors to Yumeshima, a reclaimed site in Osaka Bay. The site was reimagined through a masterplan and bounded by a Guinness World Record-breaking wooden circular structure, both designed by Sou Fujimoto Architects. Over 184 days, participants were able to visit the self-built, modular, and shared pavilions, national exhibitions, and public activities organized under the overarching theme "Designing Future Society for Our Lives." During its six-month run, the Expo set out to explore three pivotal subthemes, Saving Lives, Empowering Lives, and Connecting Lives, as an invitation to bring together new perspectives for our built and social ecosystem.
Architecture—one of the few cultural artifacts made to be publicly lived with, preserved, and often capable of standing for centuries—contributes significantly to the cultural identity of places and people. Historically, buildings have expressed institutional attitudes, influence, and power; they are clear demonstrations of culture. Yet longevity complicates preservation: when a structure is rebuilt, repaired, or entirely reassembled, in what sense is it still the same building?
There's the classic Ship of Theseus puzzle from Plutarch. if a ship's planks are replaced one by one over time, is it still the same ship? Thomas Hobbes adds a twist—if the original planks are reassembled elsewhere, which ship is "the original"? The paradox tests what grounds identity: material fabric, continuous use and history, or shared recognition. In architecture and conservation, it reframes preservation as a choice among keeping matter, maintaining form and function, or sustaining the stories and practices that give a place meaning.
Since its inauguration this spring, Expo 2025 Osaka has captured global attention from multiple perspectives, demonstrating how architecture can function as a laboratory for exploring solutions to pressing challenges. After 55 years, Osaka is once again hosting the World Expo, with each installation organized around the sub-themes Saving Lives, Empowering Lives, and Connecting Lives. These pavilions take forms that express the identity and values of their region through distinctive architectural languages, forming the central axis of their design. Building on this foundation, some installations serve as laboratories for the future society, utilizing technology to enhance experiences both inside and outside the spaces, transforming the visit through light, sound, visuals, and movement as part of the technological innovation showcased at the event.
