The thesis proposes a critical spatial approach to reveal the political, economic, and social dimensions of the urban development plans and projects (UDPs) in the context of neoliberal urban restructuring in Turkey. . It aims to enrich the theoretical and methodological foundations of critical urban studies and spatial planning, focusing on UDPs as a key neoliberal urban strategy. Despite extensive research on cities and their spaces, there is still a lack of critical understanding of the ‘urban process’, and of the actors and networks underlying these processes. The study tries to fill this gap by providing a critique of capitalism and its inherent uneven development, neoliberal political and economic restructuring, and neoliberal urban policy from a politicaleconomic perspective. The thesis concentrates on the neoliberal plans and projects produced by the state and capital as mechanisms to overcome capitalist crises. The thesis problem is to contribute to a critical urban theory that can explain and transform the socio-spatial processes in urban spaces, especially in light of the global expansion of 21st-century capitalism. The methodology used in the thesis is methodological pluralism, using various qualitative and quantitative research techniques to critically analyze the sociospatial processes of neoliberal urban restructuring.. It argues that UDPs are driven by the logic of profit and land rent, and that they exclude the participation and the rights of the poor and marginalized inhabitants. It seeks to critically elaborate on issues such as gentrification, dispossession, displacement, segregation, and polarization in the spaces of UDPs, instrumentalized as a mechanism of neoliberal urban restructuring processes in Narlıdere. Keywords: critical urban theory, neoliberal urban restructuring, urban development plans and projects, the right to the city, dispossession, Narlıdere gecekondus.
