In contemporary discourse, sustainable development now encompasses social dimensions alongside environmental and economic aspects. Social sustainability has become a key concern for researchers and planners, viewed as essential for comprehensive sustainable development. Local architecture significantly influences human behavior and social dynamics, making it crucial to examine its impact on social sustainability, especially in native cultures. This study investigates factors enhancing social sustainability in garden halls, a common public space in Ilam, a city in western Iran. Using a qualitative approach and the Delphi method, insights were gathered from 12 architecture experts. The study identifies several critical factors: consideration of local cultural nuances, quality of life enhancement, community spirit cultivation, fostering self-sufficiency, attention to geographical and climatic contexts, and creating peaceful, comfortable environments. Results reveal that public spaces, like garden halls, attract more engagement when designed according to sustainability principles that boost social interactions. This underscores a symbiotic relationship between sustainable architectural design and the promotion of social cohesion and engagement within communities.
