‘Uneasy bedfellows’ conceiving urban megastructures: precarious public–private partnerships in post-war British New Towns

From its inception, the European welfare state was a contract between the state, civic society, and the private sector. And yet, studies on the architecture and urbanism of the European welfare state frequently overlook the role played by the private sector, as the emphasis is commonly placed on governmental action. However, apart from governments also private actors played an important role in shaping the post-war welfare state. New towns in particular were sites of experiment. Here, public–private partnerships forged novel collective spaces, which challenged and redefined what constituted the civic realm. This paper focuses on one such novel type of collective space: the megastructural ‘heart’ of second-wave British New Towns. Combining mass consumption with administrative and civic functions, thereby blending the concepts of ‘shopping centre’ and ‘city centre’, these structures embodied the welfare state’s belief that capitalism could neither live with nor without the existence of a pervasive welfare system (and vice versa). Through the analysis of three megastructures, this paper highlights the important role that private actors played in the formation of the post-war British welfare state; it explicates the lofty societal ambitions that these New Town schemes expressed; and it pinpoints the precariousness of public–private partnerships in the development of urban megastructures.
