Buildner has announced the results of its Re-Form: New Life for Old Spaces, an international ideas competition examining the adaptive reuse of small-scale existing buildings. The competition invited architects and designers to propose transformations of used, abandoned, or overlooked structures with an approximate footprint of 250 square meters, located anywhere in the world. With no fixed site or program, participants were encouraged to explore alternatives to demolition and new construction through reuse strategies grounded in contemporary social and environmental concerns.

As an open-format competition, Re-Form foregrounded sustainability, feasibility, and community impact over formal or typological constraints. Submissions ranged from precise urban insertions to more speculative rural interventions, reflecting a broad range of approaches to working with existing fabric. Many projects focused on how limited, often marginal spaces could be reactivated to support new forms of collective use while responding to material, climatic, and ecological conditions.

Across Europe's major tourist cities, housing affordability has increasingly emerged as one of the most pressing urban challenges, prompting governments to reassess the role of short-term rentals within residential neighborhoods. In Barcelona, Mayor Jaume Collboni recently announced plans to phase out tourist short-term rentals entirely by 2028, framing the decision as part of a broader effort to protect residents' right to remain in the city. The announcement coincides with a €64 million fine imposed by the Spanish government on Airbnb for advertising unlicensed properties, placing Spain at the center of an intensifying debate over how tourism-driven accommodation models intersect with housing access, inequality, and urban stability.

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.
