This study aims to examine the function of architectural space in the narratives of Mustafa Kutlu from a topo-ethical or topo-poetic perspective. In Kutlu’s stories, space is designed not only as a physical setting where events take place, but also as a multilayered structure in which ethical, cultural, social, and emotional meanings are produced. Architectural spaces and elements such as the city, village, house, train station, mosque, madrasa, arcade, and courtyard are constructed as components that render the characters identities, moral stances, and social positions visible. Interior spaces and objects such as tables, curtains, televisions, radios, and similar items become symbolic indicators of class distinctions, individual alienation, and intra-family relations. Landscape elements and vegetal organization, including trees and flowers, are associated with themes of memory, change, transformation, and loss. In this study, the concept of “topoethics” is proposed as an interdisciplinary conceptual framework that enables the simultaneous evaluation of the topographical, poetic, and ethical dimensions of space. The analysis primarily focuses on stories related to the subject in the books “Ya Tahammül Ya Sefer” and “Hüzün ve Tesadüf”, while also referring to the author’s relevant essays and selected stories. In the fourth chapter, a detailed topoethical analysis of the story “Hüzün ve Tesadüf” is presented, with particular emphasis on the train station as a spatial construct. This analysis reveals a parallel between the physical transformation of space and the fate of the characters, as well as collective memory. Drawing on Maurice Merleau-Ponty’s phenomenological and perceptual understanding of space, the study determines that Kutlu’s narrative spaces are structures that are continuously spatialized together with the subject. Furthermore, it is argued that in Kutlu’s stories, architectural space integrated with the narrative plane functions dialogically as a domain of ethical responsibility and existential witnessing. This interpretation is supported through a parallel reading of the author’s views in “Şehir Mektupları” and “Akasya ve Mandolin”. In this context, this study which employs the methods of “document review” and “text analysis” within the framework of qualitative research aims to propose a new analytical approach to the interpretation of fictional and non-fictional texts through the concept of topoetics.
