Barcelona: The Latest Architecture and News

Barcelona has just become the first city in the history of the UIA World Congress of Architects to host the event twice. Thirty years separate the two editions, and the distance between them says as much about architecture's changing self-understanding as anything spoken from a stage. In 1996, the congress placed the city at the center of the debate, consolidating a post-Olympic urban model that would go on to be studied and contested for decades.

In 2026, under the theme "Becoming. Architectures for a Planet in Transition," Barcelona hosted a very different conversation. The congress's curatorial team — Pau Bajet, Mariona Benedito, Maria Giramé, Tomeu Ramis, Pau Sarquella, and Carmen Torres — organized the program around six thematic lines: Becoming More-than-human, Becoming Circular, Becoming Embodied, Becoming Interdependent, Becoming Hyper-Conscious, and Becoming Attuned. As they told ArchDaily ahead of the opening, the premise behind this structure was that most architectural decisions are, in practice, very specific — which material is used, what is demolished or preserved, how much water or energy a building consumes — yet those specific decisions carry planetary implications.

As Barcelona hosts the UIA World Congress of Architects for the second time in its history, thirty years after the 1996 edition, the city becomes a site for reflecting not only on architecture but also on the changing conditions under which it operates. Titled Becoming. Architectures for a Planet in Transition, and developed by the six-member curatorial team of Pau Bajet, Maria Giramé, Mariona Benedito, Tomeu Ramis, Pau Sarquella, and Carmen Torres, the 2026 Congress expands the discussion beyond the city toward planetary questions, addressing architecture through ecological, social, political, and material systems rather than as an isolated discipline. During the opening day of the Congress, ArchDaily spoke with Mariona Benedito and Carmen Torres, two members of the curatorial team, about how this edition revisits Barcelona's architectural legacy, why uncertainty has become central to architectural thinking, and what they hope participants will take away from the event.

Recent events highlighted the many ways architecture responds to changing environmental, social, and cultural conditions. Major earthquakes in Venezuela, Japan, and Northern California renewed attention to the role of planning, infrastructure, and building practices in shaping resilience to natural hazards. As these questions continue to inform the built environment, the opening of the 2026 UIA World Congress of Architects in Barcelona brought together practitioners and researchers to discuss climate, housing, public space, and the future of the profession. Recent project announcements, preservation initiatives, completed works, and new design tools further reflected the range of approaches shaping architectural practice today, from heritage conservation and adaptive reuse to environmental performance and long-term planning.

The exhibition What is This? A Spa, a Gym, a Zoo for Tiny Animals? is on view at the Palau Victòria Eugènia in Barcelona from May 11 to July 5, 2026. Organized by the Fundació Mies van der Rohe and curated by Anna Sala and Ivan Blasi, the exhibition presents the institution's archive through a new curatorial framework, bringing together architectural models, drawings, documents, films, and records of artistic interventions that have taken place at the Barcelona Pavilion since 1986. Open daily with free admission, the exhibition invites visitors to engage with the archive as both a historical collection and an evolving record of architectural discourse.

Barcelona is the first city in the history of the UIA World Congress of Architects to host the event twice. The 1996 edition, Present and Futures: Architecture in Cities, arrived at a charged moment, when the post-Olympic city was consolidating an urban model that would become one of the most studied and contested in contemporary urbanism, and when architecture was learning to think through the large metropolis as its primary site of inquiry. Thirty years later, the same city reopens the question under a different condition: one in which the built environment can no longer be understood as a self-contained object, but only through the wider ecological, material, and political systems that sustain it. The theme of the 2026 Congress — Becoming. Architectures for a Planet in Transition — does not abandon the urban concerns of 1996; it reopens them from a planetary scale.

The curatorial team behind this edition, formed by Pau Bajet, Maria Giramé, Mariona Benedito, Tomeu Ramis, Pau Sarquella, and Carmen Torres, approaches architecture as a critical and transformative tool rooted in territory, working across practice, research, and teaching. Their program structures the Congress around six interconnected thematic lines (Becoming More-than-human, Becoming Circular, Becoming Embodied, Becoming Interdependent, Becoming Hyper-Conscious, and Becoming Attuned) and distributes it across three venues of very different characters — Les Tres Xemeneies del Besòs, the Disseny Hub at Glòries, and the CCIB — each chosen for what it represents as much as for what it can hold.

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.

Three decades after it first hosted the event, Barcelona once again becomes the host of the global disciplinary debate. The UIA World Congress of Architects 2026 Barcelona aims to bring together 10,000 professionals, students, and institutional representatives from more than 130 countries. Discussions address topics such as the climate emergency, the housing crisis, the circularity and sustainability of materials, and the evolution of public space at large and small scales, as well as more specific topics such as the future role and responsibility of architectural awards or conferences dedicated to the DANA floods in Valencia. The daily program will be marked by two plenary sessions each day, at the start (09:00) and at the end (16:45).

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.

The city's twentieth-century transformation forged an architectural language with global influence. The principles of International Modernism are embodied in Mies van der Rohe's Barcelona Pavilion, while later developments—from Bofill's explorations in collective housing to the urban interventions of the 1992 Olympics—reshaped the skyline and the city's relationship to its waterfront. Subsequent contemporary projects continue to negotiate form, landscape, and urban scale, contributing to a layered and evolving city.

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".

This week's coverage brought together a range of news, projects, and announcements from across the architectural world. Stories included conversations ahead of the UIA World Congress 2026, where architects, critics, and award organizers are set to discuss the evolving role of architectural recognition, alongside BIG's proposal for a new university campus in Bentonville, Arkansas. The week also featured updates on major public and cultural projects, from the redevelopment of New York's Penn Station to the ongoing transformation of London's Olympia and the completion of a new cultural center in Dongguan, China. It also marked the passing of Lorcan O'Herlihy, founder of LOHA, whose practice became known for its commitment to housing, urban density, and socially engaged design across Los Angeles and beyond.

The land-water interface has always played a fundamental role in the formation and development of cities. From ancient commercial ports to today's multifunctional waterfronts, maritime and riverfront areas represent spaces of immense economic and social potential. Within this context, contemporary nautical complexes increasingly serve as strategic urban amenities capable of integrating diverse activities, fostering a reconnection between city and water, and revitalizing often underutilized landscapes.

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.

It is afternoon in the summer, and the nave of the Sagrada Família is saturated with warm colors. Shafts of amber and crimson sweep across the stone floor, shift as a cloud passes over Barcelona, then deepen again. Around you, visitors slow without quite realizing it. Some raise their phones — not to capture the architecture, but to step into the light itself, positioning themselves in a pool of orange or gold as if the colours were something you could wear.

They are, without knowing it, doing exactly what Gaudí intended: surrendering, however briefly, to the sensation of being bathed in something larger than themselves.

Modern cities are running on performance indicators. They move millions of people each day, concentrate capital, separate land uses, and sustain complex systems of logistics and consumption. In that sense, the city functions as a system to be continually adjusted and optimized.

Today's dominant metrics are familiar and widely witnessed: vehicles per hour, average commute times, floor area ratios, parking turnover, housing starts, and tax revenue per parcel of land. These figures describe a city that is legible through efficiency. They are inherited from an industrial logic, where urban space is treated more like a production mechanism than a lived-in environment. In this framing, cities begin to mimic the needs and metrics of a machine.
