Heritage design elements over the years in the UAE have undergone an evolutionary process, drawing inspiration from local heritage, cultural wisdom, and accumulated knowledge. These traditional design features contribute to shaping spaces that promote a sense of belonging and local culture within the UAE's built environment. The aim of the study is to identify these heritage design elements and reassure their crucial role in interior architecture to ultimately enhance the sustainability of interior-built environments. This research paper critically examines a recent urban development in Dubai, with a specific focus on the Al Seef heritage area, characterized by historic architecture, and a contrasting space featuring contemporary structures. The investigation identifies elements of local heritage seamlessly integrated into contemporary planning and design. The research will offer a crisp overview of the design strategy, emphasizing solutions for temperature control, humidity regulation, ventilation, and maximizing natural light to achieve sustainability goals of a built environment. By employing a mixed qualitative case study research method, the findings will be systematically organized into visual tables, providing detailed descriptions evaluation summary. Through a case study analysis, this research paper imparts valuable insights gathered from local heritage design elements. It underscores how contemporary interior architecture can effectively enhance the sustainability of any interior-built environments in modern settings. The findings contribute to a deeper understanding of the harmonious integration of heritage and sustainability in interior design, offering lessons applicable to future architectural endeavors in similar contexts.
