There are many projects on heritage areas upgrading and preservation. Still, some are more architectural or urban characteristics development-focused, others are risk-focused or impact-focused, and the majority are economic-focused. In contrast, the conservation projects need to meet all cultural heritage elements and social aspects that may enhance the opportunity for sustainable development. Therefore, the study starts with a theoretical review of each architectural, urban, and human factor related to cultural heritage through a complete sustainable framework for preserving and upgrading to meet the Sustainable Development Goal (SDG). The study reviews the global experiences approach in cultural heritage development and preservation to highlight important practical aspects that serve the developing process. Finally, the research reaches out to the importance of comprehensive sustainable development in consideration of human factors and cultural, social, and societal visions in using technology to maintain and improve heritage areas for the upcoming generation.
