2026 UIA World Congress of Architects

During a ceremony held at the World Urban Forum (WUF) in Baku, Azerbaijan, on May 20, 2026, the International Union of Architects (UIA) and UN-Habitat announced the winners of the third cycle of the UIA 2030 Award. The biennial award recognizes built projects that make meaningful contributions to achieving the United Nations Sustainable Development Goals (SDGs). Architects were invited to submit architecture, landscape, and urban design projects addressing pressing environmental, social, and economic challenges across six categories: sustainable water management, the promotion of safe working environments, adequate and affordable housing, efficient and inclusive planning, access to green and public space, and climate resilience.

Across cultural platforms, heritage sites, and institutional developments, this week's news reflects how the built environment is reshaped through processes of transformation, reinterpretation, and public engagement. From archaeological reactivations and adaptive reuse strategies to museum expansions and large-scale international gatherings, architecture operates across multiple temporalities, balancing preservation with contemporary use and spatial continuity with evolving cultural programs. Within this context, ArchDaily's selection of installations and exhibitions from Milan Design Week 2026 highlights how design weeks increasingly function as curatorial frameworks for experimentation, while global events and institutional projects continue to expand the formats through which architecture is produced, shared, and debated.

The UIA World Congress of Architects 2026 Barcelona has released its full program, outlining the structure, participants, and range of activities scheduled to take place from June 28 to July 2, 2026. Expanding on the previously introduced theme, Becoming. Architectures for a Planet in Transition, the Congress is conceived as a distributed event across multiple venues and urban contexts rather than a single-site conference. Organized by the  International Union of Architects (UIA) in collaboration with the Higher Council of the Colleges of Architects of Spain (CSCAE) and the Architects' Association of Catalonia (COAC), the event is expected to gather approximately 10,000 participants and 250 speakers from more than 130 countries.

This week, architecture presents new visions of the future across a geographically diverse landscape, with landmark projects and renewal initiatives emerging in Saudi Arabia, Taiwan, Bahrain, Germany, Italy, Australia, Morocco, and Burundi. New platforms for discussing urban futures highlight decolonization and the climate crisis as central priorities for contemporary architectural practice. At the same time, contrasting perspectives on urban regeneration are reflected in both the demolition of recent landmark structures and the large-scale transformation of industrial sites. On another note, the Olympic Games continue to act as catalysts for architectural production, as seen in the proposal for a new sports center in Australia for Brisbane 2032. This momentum coincides with major international infrastructure developments in Africa, including a new airport terminal in Morocco, as well as projects that rethink spaces for research and public engagement, such as a new building for the German Language Forum. 

More than three decades after previously hosting the event, Barcelona is set to welcome the UIA World Congress of Architects 2026 Barcelona (UIA2026BCN), bringing the global architectural community back to the city between 28 June and 2 July 2026. 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 UIA World Congress of Architects is an international event for architectural dialogue organised by the International Union of Architects (UIA, by its French acronym), a non-governmental organisation that unites national associations of architects from over 100 countries, representing more than one million professionals. The first UIA Congress of Architects, which also marked the institution's founding, was held in Lausanne in 1948 during the post-war reconstruction period. Since then, UIA congresses have been held every three years in a different city within a member country, serving as the organisation's main recurring event. In 2026, the Congress will be held in Barcelona, and UNESCO has consequently designated the city as the World Capital of Architecture 2026. Each Congress focuses on a key topic relevant to the profession, articulated through a central theme. Recent themes include Copenhagen 2023: "Sustainable Futures. Leave no one behind." and Rio 2020–2021: "All the worlds. Just one World." The topic for 2026 is "Becoming. Architectures for a Planet in Transition," welcoming renowned figures in contemporary architectural thought and practice for a broad and critical overview of the possible futures of architecture.

Architecture and design enter 2026 in a moment of renewed experimentation, urgent environmental reflection, and an expanded global dialogue on the built environment. As cities confront the pressures of climate adaptation, demographic shifts, and technological transformation, this year's international calendar offers a lens into how the discipline is responding, creatively, critically, and collectively. From long-standing biennials to newly established platforms, the events of 2026 spotlight architecture's evolving role as both a record of our changing world and a driver of more equitable, sustainable futures.

The International Union of Architects (UIA), in collaboration with UN-Habitat, has announced the launch of the third cycle of the UIA 2030 Award. Introduced in 2021, the biennial international prize highlights the role of architecture in advancing the UN 2030 Agenda for Sustainable Development, with a particular emphasis on SDG11: Sustainable Cities and Communities and the New Urban Agenda. Organized by the UIA's UN 17 SDGs Commission, the award recognizes built projects that combine architecture with measurable contributions to the Sustainable Development Goals (SDGs). Structured to coincide with the schedule of the World Urban Forum (WUF), the award will run through five cycles. 

Joining Copenhagen and Rio de Janeiro, Barcelona has been named the UIA's 2026 World Capital of Architecture by UNESCO. This title recognizes the city's commitment to promoting the values of architecture, urban planning, and sustainability. Outshining Beijing as the other contender for the 2026 title, Barcelona won the bid with its proposal titled "One today, one tomorrow," with a plan to host a series of transformative events across all its districts and become a research laboratory analyzing the capacity of architecture to transform reality over time.

The city of Barcelona, along with its metropolitan area, will become a research laboratory as the main venue for the World Congress of Architecture of the International Union of Architects (UIA), scheduled to take place from June 28th to July 2nd, 2026. Its objective is not only for the Congress to be of maximum relevance and interest to the global community of architects but also for real-impact knowledge and practices to emerge in the everyday lives of people and the future of the planet.
