C+ arquitectas is a spatial design and research practice founded by Nerea Calvillo. Their environmental mediations, commissioned by the Royal Academy of Arts, the Seoul Biennale of Architecture and Urbanism or Madrid’s local government, explore the material, social and political entanglements of the climate crisis with the spaces we live in. Calvillo is an architect, lecturer and researcher working at the intersections between spatial design, ecological futures, environmental pollution, and feminist-queer theory and methods. She is author of Aeropolis: Queering Air in Toxic Polluted Worlds, and an associate professor at the Centre of Interdisciplinary Methodologies, Warwick. Tobi Chai, Manu Alba Montes, and María Buey González, previous C+ collaborators, and Desiree Foerster have joined C+ for Air Ecologies. Chai is a multidisciplinary artist and researcher operating across the cultural, research and human rights sectors. Alba is an architect, designer, DJ, and multidisciplinary artist. Buey is an architect working on the implications of automation and computational technologies on the built environment. Foerster is a new media arts and design researcher interested in the ways cognitive processes and practices of embodiment are taken up in the Arts.
