City of Barcelona.

Organized under the theme “Becoming. Architectures for a Planet in Transition,” the Congress is expected to gather approximately 10,000 participants from over 130 countries, including practitioners, researchers, and students. Rather than being confined to a single venue, the event will unfold across multiple locations along the Mediterranean seafront, among them the Three Chimneys complex , positioning the city itself as an active platform for exchange, discussion, and public programming.

The selection spans regulatory measures affecting housing markets in European cities, high-density residential and mixed-income proposals in New York , and major renewal and planning efforts in London , Barcelona , Ulaanbaatar , and Drammen . It also highlights research-driven and built projects in Chicago , Buenos Aires , Las Vegas , and Riyadh that explore circular construction, adaptive reuse , and new models for cultural and public infrastructure. Together, these worldwide projects offer a snapshot of how architecture and urban planning are addressing immediate pressures while laying the groundwork for more resilient and inclusive urban futures across diverse geographic and cultural contexts.

Since then, UIA congresses have been held every three years in a different city within
