A building material rarely begins where architecture encounters it. By the time concrete reaches a construction site, its limestone has already been quarried, processed, and transformed. Timber arrives long after the forest. Glass appears detached from the sand from which it was made. By the time materials enter construction, much of the landscape and industry that produced them has already disappeared from view.
For some time now, it has become common for us to ask where what we consume comes from. We check labels, look for local producers, and investigate supply chains in an attempt to understand the impact of our habits—on our own health and on the planet.
The UIA 2026, the 29th edition of the triennial international event for architectural dialogue organised by the International Union of Architects, has opened its doors on Sunday, June 28th, with an inaugural event held at Three Chimneys, a former power plant in Sant Adrià de Besòs. Each Congress focuses on a pressing topic relevant to the profession, articulated through a central theme. The topic for 2026 is "Becoming. Architectures for a Planet in Transition," calling for a broad and critical overview of the possible futures of architecture. The event runs through July 2, 2026, as a distributed event across multiple venues and urban contexts. With a multidisciplinary approach, Barcelona, the UNESCO World Capital of Architecture 2026, is set to become a global laboratory and hub for debating forthcoming ecological, social, material, and cultural transitions.
Long before it becomes a matter of performance, comfort, or energy efficiency, natural light is a way of giving presence to architecture. It reveals the texture of a wall, the depth of an opening, and the silent passage of time within a space. In works as distinct as those of Tadao Ando and Alvar Aalto, daylight appears as an essential material of design: in some cases, guiding the eye toward contemplation; in others, making spaces feel more human, welcoming, and connected to everyday life.
Barcelona is a city where architecture has long served as a laboratory of urban experimentation, each era leaving its mark on the city's fabric. From the dense streets of the Gothic Quarter to the ornate interiors of the Palau de la Música Catalana, the city expanded outward through Ildefons Cerdà's Eixample, a stage where Gaudí and his contemporaries challenged the rules of form, scale, and ornamentation. These experiments defined a local identity and culminated in the Sagrada Família, a vision that continues into the 21st century through the integration of advanced technology.
Every three years, the International Union of Architects' (UIA) World Congress lands in a different city, under a different theme set years in advance. A quick mapping of these host cities reveals a deliberate pattern: throughout the decades, the UIA has purposefully chosen a wide range of venues across all continents, rendering each edition a snapshot of what mattered in that specific place, at that exact moment. The result of this geographic rotation has been a diverse kaleidoscope of conversations, analyzing the profession from countless angles and adapting it to changing times. But 2026 is different; this time the UIA is repeating a host city for the first time: Barcelona, under the theme "Becoming. Architectures for a planet in transition".
There is a standard way of telling the history of architecture and food. It begins with the human decision to cultivate, to store, to distribute, to consume, and ends with the building that decision produced. In this version of events, food is the occasion and architecture is the response.
A collective discussion titled "Beyond Recognition: Exploring the Role of Architectural Awards" is taking place on June 29 in Barcelona, on the occasion of the UIA World Congress of Architects 2026. The debate starts from the conviction that, in today's context of accelerating global challenges, the role of architectural awards must evolve. The event follows the conversation initiated during the 2025 Venice Architecture Biennale, where the relevance of awards was questioned, paving the way for a new conversation on how architectural awards can contribute to shaping practice, institutions, and public discourse. The discussion sessions are convened by representatives of major international awards: the Aga Khan Award for Architecture, Ammodo Architecture Award, EUmies Awards, Holcim Foundation Awards, Mies Crown Hall Americas Prize, and the OBEL Award, and are joined by prominent figures in the field of architecture and design.
