This thesis examines the socio-spatial consequences of neoliberal urban policies and luxury developments by the waterfront in Istanbul’s coastal neighbourhood of Ataköy. Focusing on Ataköy’s 2-5-6th section neighbourhood and urban developments located at its waterfronts, luxury housing projects, and commercial functions, the research explores how these transformations affect urban resilience, spatial justice, and residents' perceptions of their changing urban environment. Guided by two main research questions, the study adopts a qualitative case study methodology incorporating field observations, interviews with residents, local authorities, and NGOs, as well as the analysis of planning documents and policy texts. Findings reveal that although Ataköy continues to offer a relatively high quality of life due to its planned layout and green character, residents have expressed growing concerns regarding the privatization of public space, weakening community cohesion, and environmental degradation.
