In this paper I develop an argument for the specific contribution which archaeology might make to the study of the ‘classic’ welfare state in Britain (c. 1945–1975) and its aftermath (c. 1976 to present). This period saw massive state investment in infrastructure which transformed both the material and social worlds of its citizens, through new state policies, new networks of political and social control, the centralisation and nationalisation of a range of existing aspects of civilian life and the construction of housing on a monumental scale. While this is a topic which has been studied in detail by historians and sociologists, despite the massive investment in construction and the accompanying effects on the physical landscape of Britain, there has been relatively little work on the ‘material worlds’ of the welfare state. In developing this argument I focus particularly on public housing, an area which has been the subject of some previous archaeological comment and which provides a clear case study in the contribution which such an approach might make.
