Boltshauser Architekten: The Latest Architecture and News

Concéntrico Festival 2026 will take place in Logroño, Spain, from June 18 to 23, transforming the city into a large-scale laboratory for architecture, design, and urban experimentation. Over six days, more than twenty interventions will be distributed across squares, vacant plots, streets, bridges, and emblematic spaces throughout the city, bringing together leading studios, researchers, and creators from the international scene, including Chilean architect Smiljan Radić, the raumlabor collective, Matilde Cassani, AAU Anastas, and Sahra Hersi, among others. This edition introduces a shift towards more collective, festive, and performative practices in public space, with a strong emphasis on sonic experiences and projects linked to accessibility, inclusion, and urban transformation. The programme is structured around three thematic axes: Identity and Fiction, Urban Ecologies, and Ephemeral Agents, ranging from architectures that understand public space as ritual or celebration to experimental approaches exploring materials, sound, and processes of reuse.

Concéntrico, the Spanish laboratory for urban innovation exploring new ways of inhabiting public space through temporary urban installations, presented the program for its upcoming edition on March 17th, along with its main lines of work for the 2025–2026 season. The festival invites architects, designers, artists, and researchers from different geographies to propose interventions that activate squares, streets, riverbanks, and vacant spaces in the city. This year's edition includes the participation of Smiljan Radić, the recently awarded Pritzker Architecture Prize laureate, who will develop a light, foldable, and temporary structure built from industrial plastic fabrics following the concept of a "poor circus." Another 26 teams, including three practices selected through the festival's international open calls, will intervene in Logroño's public space from June 18 to 23, 2026, with projects ranging from climate-responsive structures to ephemeral public space activations.
