Architecture and Anarchism documents and illustrates 60 projects, past and present, that key into a libertarian ethos and desire for diverse self-organized ways of building. They are what this book calls anarchist' architecture - forms of design and building motivated by the core values of autonomy, voluntary association, mutual aid and direct democracy. The projects highlight the stark gap between the autocratic way in which the built environment is generally governed and the aesthetic liberation that is vital to a full human flourishing in cities. They show how authoritarianism can sometimes be held at bay by differing kinds of libertarian politics. Taken as a whole, they are meant as an inspiration to build less uniformly, more inclusively and more freely.
