Reconstructing modernity assesses the character of approaches to rebuilding British cities during the decades after the Second World War. It explores the strategies of spatial governance that sought to restructure society and looks at the cast of characters who shaped these processes. It challenges traditional views of urban modernism as moderate and humanist, shedding new light on the importance of the immediate post-war for the trajectory of urban renewal in the twentieth century. The book shows how local corporations and town planners in Manchester and Hull attempted to create order and functionality through the remaking of their decrepit Victorian cities. It looks at the motivations of national and local governments in the post-war rebuilding process and explores why and how they attempted the schemes they did. What emerges is a picture of local corporations, planners and city engineers as radical reshapers of the urban environment, not through the production of grand examples of architectural modernism, but in mundane attempts to zone cities, produce greener housing estates, control advertising or regulate air quality. Their ambition to control and shape the space of their cities was an attempt to produce urban environments that might be both more orderly and functional, but also held the potential to shape society.
