At the UIA World Congress of Architects 2026 in Barcelona, the theme Becoming. Architectures for a Planet in Transition framed architecture as a discipline operating within environmental, political, and social transformations rather than outside them. Among the speakers participating in this edition was architect Andrés Jaque, founder of the Office for Political Innovation and Dean of Columbia University's Graduate School of Architecture, Planning and Preservation (GSAPP). During the Congress, ArchDaily spoke with Jaque about architecture's capacity to generate alternatives, the role of experimentation in education, and why transition should be understood as a condition rather than a destination.

Public space is often understood as belonging to no one in particular, collectively accessible yet institutionally maintained, yet a growing number of initiatives are challenging this assumption by testing shared management and distributed ownership models. In Paris, Adoptez un banc introduces a sponsorship-based approach, allowing individuals and groups to support temporarily and symbolically claim responsibility for historic public furniture without compromising its collective use. Elsewhere in the city, community gardens operating under the Main Verte framework demonstrate a self-managed model, in which public and private landowners retain ownership while delegating day-to-day control to citizen associations for food production and shared use. In New York, Common Corner represents a third pathway, based on institutional collaboration and participatory design, where public agencies, nonprofits, designers, and residents co-produce public space within a public housing context. Taken together, these three cases suggest that care, authorship, and responsibility can be distributed across citizens and institutions, producing more resilient, locally grounded urban environments.

What allows a single architectural principle to generate many different outcomes? The answer lies in the systems that organize architecture: geometry, proportion, structure, and construction. Together, these can establish a set of rules that can accommodate different programs, contexts, and spatial conditions while maintaining a coherent identity. A structural grid, for example, can organize a variety of uses, just as a single construction detail can be repeated throughout an entire building without producing identical spaces. Can the same way of thinking be translated into furniture design without losing its identity? MTM—Made to Measure, developed by Herzog & de Meuron for UniFor, explores this question. Instead of designing each piece independently, the collection grows from a single structural principle that can be extended, adapted, and repeated across different functions while maintaining its internal coherence.
