This book takes a close look at the interrelated phenomena of international business migrants and rural migrant workers in Shanghai. Through separate case studies it observes them in parallel and sheds light on the spatial implications of both groups' migrant status. The authors' uncovering of harsh and inadequate living and working conditions affecting rural migrant workers in the construction industry in Shanghai leads to the development of a concept of »Fair Building«, a socially-conscious architecture that calls for accountability in ensuring that stakeholders involved in the construction process contribute to a sustainable urbanization.
