Revolutions of Choice marks Barkow Leibinger's third edition of their atlas series following Bricoleur Bricolage (2013) and An Atlas of Fabrication (2009). Complimenting Barkow Leibinger's retrospective exhibition of the same title at the Haus am Waldsee in Berlin (2020) this manual-like format, like the earlier editions, focusses on the practice's material experimentation and research with an emphasis on processes. Rather than a chronological ordering of projects these investigations are selected around six work areas: bundles, casting, topographical, liminal façade, ultrastructural, and frames. Produced between 2014 and 2021 this collection marks Barkow Leibinger's ongoing commitment to architecture as an evolving discipline that responds to emerging technologies and materiality and how imagination and experimentation harness them.
