Human history has seen many settlements transformed or built entirely by expatriate work forces and foreigners arriving from various places. Recent migration patterns in the Gulf have led to emerging 'airport societies' on unprecedented scales. Most guest workers, both labourers and mid to high-income groups, perceive their stay as a temporary opportunity to earn suitable income or gain experience. This timely book analyses the essential characteristics of this unique urban phenomenon substantiated by concrete examples and empirical research. Both authors have lived and worked in the Gulf including Qatar, Bahrain and the United Arab Emirates during various periods between 2006 and 2014. They explore Gulf cities from macro and interconnected perspectives rather than focusing solely on singular aspects within the built environment. As academic architects specialised in urbanism and the complex dynamics between people and places the authors build new bridges for understanding demographic and social changes impacting urban transformations in the Gulf.
