Through an ethnographic analysis of housing in the Arabian Gulf State of Qatar, this study explores the production and reproduction of social diversity through the articulation of social and spatial process. Since the discovery and commercial exploitation of Qatar's oil and natural gas resources, the city of Doha has been transformed from a relatively small and homogenous coastal town into a modern metropolis with a multinational population. As foreign workers have been recruited to live and work in Qatar, the spatial organization of the city has been altered to accommodate the population growth providing the opportunity to examine the relationship between these concurrent social and spatial changes. In this research, I combine the insights of earlier works in anthropology that explore the relationship between the built environment and social structure with theories of social production, to explore the ways in which the built environment is instrumental in the organization and maintenance of diversity in Qatar.^ Throughout this work I am interested in the ways in which buildings, particularly the house, produce and reproduce social relations as such the house is considered a concrete cultural artifact through which complex social relations are linked. In addition to providing ethnographic material illustrating how the house is linked to local and global hierarchies, flows of foreign capital and labor, bureaucratic structures, and local cultural values and practices, this study also addresses a number of themes which contribute to our understanding of social change and social diversity in the context of increased globalization, including the existence and interaction of multiple ideologies of diversity, the dynamic interpenetration of micro and macro-level practices, and the importance of the dual processes of exclusion and inclusion for the structuring of social diversity.
