This study examines how traditional Saudi vernacular architecture can be strategically integrated into contemporary urban development as a culturally grounded and sustainability-oriented design approach, rather than as a symbolic or esthetic reference. While heritage-led urban projects are increasingly promoted within Saudi Arabia’s Vision 2030 agenda, the existing scholarship has insufficiently addressed how vernacular architectural principles operate as socio-cultural systems within modern urban frameworks. Drawing on theories of vernacular architecture, adaptive reuse, and culturally responsive urbanism, this study conceptualizes “integration” as the functional, spatial, and social re-embedding of traditional architectural logic within contemporary planning processes. Using a convergent mixed-methods design, the study integrates comparative case study analysis with primary data from expert interviews and structured survey questionnaires administered to residents and visitors. Secondary demographic and policy documentation were analyzed to contextualize the case studies and support triangulation of findings. The findings demonstrate that projects that meaningfully integrate vernacular principles, such as climate-responsive construction, spatial hierarchy, and material authenticity, contribute to strengthened cultural identity, enhanced environmental performance, and increased public acceptance of urban transformation. The study further reveals that modernization does not inherently conflict with heritage preservation when guided by context-specific policy frameworks and community engagement mechanisms. By explicitly linking vernacular architecture to sustainability, socio-cultural continuity, and urban governance, this research offers an original contribution to heritage and urban studies. It provides evidence-based insights for policymakers, planners, and designers seeking to balance rapid urban growth with the preservation of cultural identity in Saudi cities and comparable contexts.
