This thesis aims to examine the work of, Erbil Coşkuner, one of the prominent names of modern Turkish architecture in İzmir. The thesis adopts a chronological layout in order to contextualize Coşkuner's career against the historical background that influenced him. The text is divided into three sections to periodize his career in order to shed light on the formative influences behind Coşkuner's career as an architect, as well as his intellectual development. The main aim of the thesis is not to position Erbil Coşkuner as a "leading actor" of İzmir and Turkey's architectural scene and to construct a hagiographic narrative, but rather to understand his career within a broader historical framework. The thesis is partially based on a series of open-ended interviews held with Coşkuner in person, and recorded with his consent. The interviews laid the groundwork for further research into Coşkuner's personal archives as well as publications based on his work. The primary material collected after the archival research and the interviews which helped construct a micro-history of the architect's career was then evaluated against histories of modern Turkish architecture. The thesis thus aims to question as well as contribute to this framework through the lens of Coşkuner's career.
