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.

In architecture, however, this question still remains relatively marginal. We often know who designed a building, we are familiar with its finishes, the manufacturer of its window frames, the brand of its cladding systems, and even its energy performance—but we almost never ask where the tons of material that made its existence possible came from.

Set on the banks of the Sava River in Belgrade, Serbia, the site of a former cement factory became the starting point for the 21st edition of the Saint-Gobain Architecture Student Contest. Organized in cooperation with the World Green Building Council, OneClick LCA, the City of Belgrade, the Academic Yachting Club Belgrade, the Serbia Green Building Council, and the Green & Blue Corridors Association, invited students to imagine a new Sports and Recreation Hub capable of transforming an industrial waterfront into a year-round public destination. More than 200 universities from 34 countries participated in this 21^stedition of the Architecture Student Contest.

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.

International firms Studio Gang and Henning Larsen have completed Breakthrough Properties' One Milestone. The life science development is part of the first phase of Tishman Speyer and the Harvard Allston Land Company's Enterprise Research Campus (ERC), a 14-acre mixed-use district in Boston's Allston neighborhood. Located on the southwest end of the ERC, One Milestone is intended to serve as a hub for creativity, science, and entrepreneurship. Its recently inaugurated two-building complex, spanning 47,380 sqm, was designed to serve Greater Boston's scientific community. The two firms began collaborating on the project in 2019 with the co-design of a strategic framework plan, breaking ground on One Milestone in 2023.

Across different climates and building cultures, many contemporary projects are working with local ways of building in new ways. Earth walls, bamboo structures, shaded thresholds, and collective construction processes are being reconsidered not as references, but as tools for the conditions architecture is facing now and will continue to face.

In these projects, vernacular knowledge appears through practical decisions: how to cool a building without machines, how to build with what is nearby, how to make a structure easier to repair, and how to keep construction knowledge within the community that will use it. The conditions making this knowledge necessary are not coming. They are already here.

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.

Bjarke Ingels Group (BIG) has unveiled new images of the National Juneteenth Museum, offering a closer look at the design of the 72,000-square-foot institution planned for Fort Worth, Texas. Designed in collaboration with Alligood Song Architecture and architect of record KAI Enterprises, the project is scheduled to begin construction in fall 2026 and will serve as a national center dedicated to preserving the history and legacy of Juneteenth. Led by activist Dr. Opal Lee, widely recognized as the "Grandmother of Juneteenth," the museum combines exhibition spaces with community-oriented programs intended to support both cultural preservation and neighborhood revitalization.
