Living Architecture: The Role of Intermediate Spaces in the Social Sustainability of Andean Rural Housing

The rural dwelling in southern Ecuador’s Andean region is the product of a long-term process of cultural and technical hybridization in which colonial typologies are overlaid with local building know-how adapted to temperate and cold climates. This study examines how intermediate spaces—portals, hallways, patios, porches, and corridors—operate as fundamental strategies for social sustainability. These spaces facilitate interaction between domestic interiors and the surrounding environment, mediate social relations, and accommodate productive, ritual, and everyday practices. Methodologically, the research integrates morphological and typological analysis with ethnographic methods and detailed graphic representations, yielding a spatial ethnography of thirty-five dwellings distributed across distinct ecological zones of Loja Province. The findings reveal how intermediate spaces undergo transformation, appropriation, and reconfiguration over time, demonstrating notable functional adaptability while maintaining cultural continuity. Beyond environmental and climatic functions, these spaces act as vital hubs of community life, sustaining intergenerational knowledge transmission, syncretic rituals, and household microeconomies. Their logics of spatial mediation and multifunctionality position them as key architectural devices that foster the social and cultural resilience of Andean rural housing. Understanding their configuration and use offers actionable insights for contemporary design, enabling the critical reinterpretation of vernacular principles to address ongoing challenges of habitability, sustainability, and belonging in evolving rural contexts.
