The Afterlife of Expo Osaka’s Grand Ring: How the Timber Structure Is Being Reused Across Japan

February 18, 2026 Antonia Piñeiro 0

Exhibitions can be an opportunity to extend architectural discourse beyond professional circles, opening conversations with broader publics and serving as an interface between architecture and society. Within this concept, major international events such as the Osaka International Expo 2025 and the Venice Architecture Biennale have adopted the idea of the circular economy as one of their organizational objectives. The idea of circularity in events can be reflected in, for example, their energy consumption, the impact of the displacement they generate, their waste, or the useful life of their infrastructure. The site destined for the last World Expo, held in Osaka from 13 April to 13 October 2025, was surrounded by a massive timber structure designed by Sou Fujimoto Architects, one of the world’s largest wooden constructions. The Japan Association for the 2025 World Exposition committed to reusing building materials “as much as possible,” with concrete plans for their reuse to be finalized by March. In the meantime, some relocation alternatives are already emerging for the pieces of the World Expo structure.

The Two Cathedrals of Managua: Architectural Memory After Nicaragua’s 1972 Earthquake

February 18, 2026 Moises Carrasco 0

On December 23, 1972, Managua, the capital of Nicaragua, was struck by a 6.3-magnitude earthquake. In a matter of minutes, its urban core, which for decades had functioned as a compact political and economic center, abruptly collapsed. In the reconstruction process that followed, the authorities sought not simply to rebuild but to reorganize. Their objective was to decentralize the city and prevent future paralysis by dispersing functions across multiple zones. Among the most significant architectural outcomes of this shift was the new Metropolitan Cathedral. Its modernist language symbolized both institutional continuity and urban transformation. In doing so, it embodied Managua’s transition from a Spanish-style, centralized urban grid to a contemporary, decentralized metropolis.

In 2022, Michan Architecture, together with Parabase and Taller de Paisaje Entorno, won an international design competition for three new pavilions and a landscape project in Chapultepec Park, one of the largest and oldest parks in Latin America. Most of the mass of the project is generated by reusing the site’s own resources, respecting existing trees and minimizing waste.

Havenwood / Atlas Architects

February 18, 2026 Miwa Negoro 0

Havenwood House began with a family gift: a block of land in a quiet Brighton cul-de-sac. What followed tested the project at every turn—planning disputes, a drawn-out VCAT process, the collapse of the original builder, and ultimately a complete rethink of the design. From these challenges emerged a light-filled home that reconsiders the suburban backyard, placing nature, community, and long-term living at the forefront of everyday life.

Ger Plug-In 3.0 / District Development Unit

February 18, 2026 Miwa Negoro 0

Over 840,000 people live in the ger districts of Ulaanbaatar, Mongolia, sprawling districts of gers (traditional felt tents) and self-built houses. Most households use an average of 4.1 tons of coal or coke briquettes for heating each winter as temperatures drop below -30°C. There is no sewage or sanitation infrastructure: 95% of residents use pit latrines, 1% have access to piped water, and air pollution is extremely debilitating to health.

Entremontes House is a single-family residence located on a rare urban site between two hills that shape the skyline of Montenegro, in southern Brazil. Set on a 5,000 m² plot, the project embraces a unique condition where urban infrastructure coexists with natural landscapes. Designed by Harpa Arquitetura, the house explores this duality by carefully mediating the relationship between city and nature.
