ABSTRACT
This chapter addresses the two questions that are the focus of the research in the light of the case studies. It provides a some explanations as to why and how Simplified Planning Zones (SPZs) have been used for reasons at variance with their Thatcherite aims. The chapter identifies areas for further research and discusses what this tells about the wider Thatcherite changes to planning. Although physically suitable the proximity of the zones with the potential of a variety of uses led to uncertainty for adjoining residential areas. The physical suitability aims of the government lacked wider objectives. The government had to force them upon some local authorities through their control of resources such as the City Grant in Derby and the power to impose an Urban Development Corporation in Birmingham. The most important socio-economic change that affected SPZs and the government's wider policy of property led urban regeneration was the recession at the end of the 1980s.
