Bracket is a book series that highlights emerging critical issues at the juncture of architecture, environment, and digital culture. Seeking new voices and design talent, Bracket is structured around an open call for entries. Conceived as an almanac, the series looks at emerging thematics in our global age that are shaping the built environment in radically significant, yet often unexpected ways. Bracket 4: Takes Action examines design work and theoretical papers that offer contemporary models of spatial design that are conscious of their public intent and actively engaged in sociopolitical conditions. Takes Action investigates how design at several scales and within differing disciplines can catalyze a public, as well as forums for that public to act.
