The OBEL Foundation has announced "Systems' Hack" as the focus of its 2026 cycle, setting the conceptual framework that will guide the foundation's activities and the selection of the next OBEL Award. Founded in 2019, OBEL recognises architecture's potential to act as a tangible agent of positive social and ecological change, supporting approaches that expand how the built environment is defined and shaped. The 2026 theme calls on architecture to critically engage with the systems that underpin contemporary society, including infrastructure, energy, food, water, education, and information, and to examine how these interconnected networks might be reconfigured in response to accelerating global challenges.
