Spatializing Justice calls for architects and urban designers to do more than design buildings and physical systems. Architects should take a position against inequality and practice accordingly. With these thirty short, manifesto-like texts—building blocks for a new kind of architecture— Spatializing Justice offers a practical handbook for confronting social and economic inequality and uneven urban growth in architectural and planning practice, urging practitioners to adopt approaches that range from redefining infrastructure to retrofitting McMansions. These building blocks call for expanded modes of practice, through which architects can imagine new spatial procedures, political and economic strategies, and modalities of sociability. Challenging existing exclusionary policies can advance a more experimental architecture, one not bound by formal parameters. Architects must think of themselves as designers not only of things but of civic processes, complicate the ideas of ownership and property, and imagine new sites of research, pedagogy, and intervention. As one of the texts advises, "the questions must be different questions if we want different answers." Cruz and Forman are principals in ESTUDIO TEDDY CRUZ + FONNA FORMAN, a research-based political and architectural practice in San Diego. They lead a variety of urban research agendas and civic/public interventions in the San Diego-Tijuana border region and beyond. The work has been exhibited widely in prestigious cultural venues across the world.
