Centred on design-based investigations into two polarised Danish urban landscapes, this book outlines the contours of an urbanism of entanglement. Urban design is fundamentally reconceived as a relational practice that mediates processes of continuous transformation, and which works through entanglement of existing as well as proposed material conditions, ideas and practices. Thus site survey is considered the key to formulating design strategies. Pioneering for urban design research it is demonstrated how actor-network-theory can explicate urban design as both knowledge form and design action.
