Concéntrico: Urban Innovation Laboratory reflects on the first decade of the international Concéntrico festival in Logroño, Spain, and the 150 projects and designs commissioned for it. The festival’s aim is to serve as a laboratory searching for creative ways of using architecture and design to strengthen communities and to support the dialogue between designers and citizens. The book offers a unique meditation on the transformation of cities and the relevance of architecture and design in the 21st century. It introduces meaningful ways to address and engage with pressing urban issues—from identity and heritage to temporariness, collectivity, ecology, play, and domesticity—through the lens of selected Concéntrico commissions since 2015. Lavishly illustrated and with concise texts, it features 86 projects by artists, architects, and designers from 20 countries. These are prefaced and held together by a conversation between the editors Javier Peña Ibáñez and Nick Axel, who speak about the festival’s context, evolution, and the knowledge it has produced over a decade.
