Once again, architecture is looking at itself in the mirror. Theorists and practitioners are reorienting the field’s tools and methods to address social complexity at the scales of both systemic conditions and interpersonal exchange. These expanding modes of practice suggest that the centre of architecture is shifting and cannot hold. Approaching this shift in multiple ways, contributors Bryony Roberts (introduction), Peggy Deamer (feminist architecture), Katy Barkan (reshuffling hierarchies), Ana Miljacki (collective learning), Jia Yi Gu (cultivating care), Mabel O. Wilson (decolonising practice), Margo Handwerker (parsing social practice), and others weigh in on the issue.
