Over the last decade, 'parametricism' has been heralded as a new avant-garde in the industries of architecture, urban design, and industrial design, regarded by many as the next grand style in the history of architecture, heir to postmodernism and deconstruction. From buildings to cities, the built environment is increasingly addressed, designed and constructed using digital software based on parametric scripting platforms which claim to be able to process complex physical and social modelling alike. As more and more digital tools are developed into an apparently infinite repertoire of socio-technical functions, critical questions concerning these cultural and technological shifts are often eclipsed by the seductive aesthetic and the alluring futuristic imaginary that parametric design tools and their architectural products and discourses represent. The Politics of Parametricism addresses these issues, offering a collection of new essays written by leading international thinkers in the fields of digital design, architecture, theory and technology. Exploring the social, political, ethical and philosophical issues at stake in the history, practice and processes of parametric architecture and urbanism, each chapter provides different vantage points to interrogate the challenges and opportunities presented by this latest mode of technological production.
