The AA Book 2021 celebrates the depth of research and plurality of practice pursued at the Architectural Association (AA) during the 2020-21 academic year.  The publication features hundreds of projects by students from every unit and program within the school, which together document the AA as an environment where architecture is investigated as a form of knowledge that aims to address the most urgent questions we face in contemporary society. The work featured within this book is the outcome of circumstances that have challenged the entire school community over the past year; to rethink how designers approach the environment, to reinvent practice so that we can address societal inequality and to reconsider how our space can foster a sense of care.  Collectively, these reimagined buildings, reconceptualized cities and regenerated landscapes seek to establish a future that is more sustainable, equitable and democratic. Complementing these projects are a series of thoughts and provocations that reveal the AA’s commitment to remaining nimble and at the forefront of architectural culture and learning, both today and tomorrow.
