Evaluating change in housing for sustainable development: Kosuyolu case in Istanbul

Sparse attention has been paid to the inevitable processes of change that enable progress in today's globalizing urban centres, but also threaten their unique identity, historic memory, and cultural heritage. The aims of this work are to understand the urban dynamics that trigger these change processes, uncover their effects, and discuss how these changes can be utilized to achieve sustainable development. The case study, which uses a comparative mixed method strategy consisting of archival research, fieldwork, and Semi-Structured interviews, is the Kosuyolu Housing Settlement, a project dating to the 1950s that represents one of Istanbul's best examples of urban development and housing culture. Displaying the architectural and urban planning ideals of the Modern period, this settlement is a concrete example that reflects the period's considerations regarding social housing. Through this case, change in housing has been evaluated in terms of sustainability indicators. The derived evidences show the significant role of governance and the maintained land use pattern for the achievement of the sustainable development and these evidences are used to suggest the development of an adaption guide that will assist in sustainable development in the short term, and the creation of alternative scenarios that are flexible and easy to adapt, active, and based on participatory processes for the long term.
