This course aims to enable students to understand that housing is not only a physical shelter but also a social, economic and political phenomenon. The course covers the historical origins of the housing crisis, its spatial consequences, current housing policies, state interventions, market dynamics and the process of financialisation and commodification of housing. It is aimed that the students will be equipped with the theoretical knowledge to evaluate the processes of housing production and distribution in different contexts, to think critically and to interpret them from the perspective of interior architecture and environmental design. The course examines the transformation of the concept of housing by introducing the historical and social dimensions of housing. The role of the state and the market is analysed through themes such as housing crises since the Industrial Revolution, modern housing policies, social housing practices and the financialisation of housing. Current housing crises, right to housing, spatial justice, gentrification, access to housing are discussed with global and local examples. In addition, students gain the ability to evaluate the effects of housing policies on interior architecture and environmental design disciplines.
