<p>This study explores the spatial role of sofa spaces as the central element in traditional Turkish houses, focusing on regional variations across twenty-one houses selected from seven distinct geographical regions of Turkey. Using space syntax analysis and Real Relative Asymmetry (RRA) values, the research examines how sofa spaces are integrated within the overall spatial configuration. Results reveal that inner and lower-floor sofas typically exhibit higher integration, while upper-floor, corner, or outer sofas tend to be more segregated. The findings also indicate that climatic and topographic factors significantly influence the spatial positioning and typology of sofas. The study contributes to understanding how environmental context shapes vernacular housing and demonstrates the effectiveness of syntactic analysis at the domestic scale. By quantitatively evaluating a core architectural element, this research provides new insights into the socio-spatial logic of traditional Turkish domestic architecture and presents a replicable methodological approach for future regional studies.</p>
