This chapter discusses the suburban, postindustrial, and holistically planned developments such as the Cambridge Science Park. These were initiated and managed by a single authority, usually a private developer, and hosted a mixture of offices, light industry, and private research centers. The chapter also highlights the emergence of the business park, which the author described as a host of different developments that at various times have been called “office parks,” “science parks,” “research parks,” “industrial parks,” or “technology parks.” The chapter then looks at the history of a new late-twentieth-century urban form, looking at the kinds of working subjects that this form hoped to produce and attract, and its relationship to the state and the wider world. Ultimately, the chapter traces back where the book began, at Trafford Park. Ruined by deindustrialization and choked by geography, Trafford Park was transformed by a state development corporation into a massive business park by the 1980s. As with the private housing estate and shopping mall, this new urban form required a reimagining of the old.
