Housing is what creates and defines cities, and affordable housing is what makes successful and scalable cities. Indeed, housing is the spatial expression of a society’s values and morality, and of its commitment to an inclusive society. In the Gulf region, characterized by rapid urbanization and astonishing transformation over the last two decades, housing is absolutely urgent as a national priority. The Gulf region has an unusually large number of factors that make the emergence and development of quality affordable housing a challenge without obvious parallels or examples elsewhere in the world. As a result, the region presents a set of housing and affordable housing delivery challenges unique in their own right. These challenges will require solutions based on innovation in both the private and public sectors.
