Arquitectura Viva 274: Expo Osaka 2025

Visitable until 13 October is the World Expo of Osaka, the Japanese city’s second. If in 1970 the future envisioned was one of steel and concrete, this time the fair is a sampling of sustainable construction that will leave no built legacy: the premises will be totally dismantled to let the artificial island recover its port function. To cover this huge event, 'Arquitectura Viva' presents a full article signed by Néstor Montenegro, Fernando Muñoz, Rocío Pina, and Carmelo Rodríguez, the designers of the Spanish Pavilion, who highlight the conceptual swerve of an exposition historically characterised by excess and deficits. It is followed by a dossier of twelve national participations that features interesting exercises in innovation, in which local sugi wood will either give the buildings a second life or return materials to the production chain.
