The recent search for cultural identity in Saudi Arabia has raised many questions about the direction of growth after the post-oil era to afford a sustainable future. Several heritage rehabilitation projects have been launched at various scales in the country to revitalize the value of local culture and traditions. The paper presents research about the urban heritage rehabilitation projects in some selected Saudi Arabia case studies. The research methodology assessed the sustainable criteria and principles adopted during the interventions to enhance the heritage's environmental, ecological, social, cultural, and economic values and target long-term holistic sustainable reuses in compliance with the UN's 17 Sustainable Development Goals. The assessment was done through a questionnaire spread among various participants in the community, including inhabitants, tourists, governmental offices, and educational institutions. Results show that sustainable reuses have enhanced socio-cultural and economic principles by promoting social cohesion and local investment. Restorative approaches have adapted more to users’ needs, while conservative methodologies have preserved the authenticity of old uses.
