Abstract : Exposure to nature within hospital settings creates healing environments that effectively reduce patients’ stress and enhance their well-being, leading to shorter hospital stays. This connectivity with nature also benefits visitors, families, and healthcare workers. However, establishing a direct connection with nature can be challenging within sterilized environments. Biophilic design serves as an approach that reflects the characteristics of nature, both directly and indirectly, within built environments, positively impacting health and well-being. Nevertheless, only few studies discuss biophilic design implementation within hospitals in Bahrain. This thesis aims to examine the incorporation of biophilic design in Bahraini hospitals and offer insights into methods of enhancing the quality of these spaces by emphasizing the creation of environments that optimize healing for all users through connectivity with nature. The thesis mainly focuses on quantifying visible and tangible biophilic design aspects in Bahraini hospitals and examining their application methods. The first stage of the thesis employs a qualitative approach to explore Bahraini hospitals that incorporate biophilic design, resulting in the selection of five private hospital case studies. The second stage uses a combination of qualitative and quantitative methods, including photographic documentation and the Biophilic Interior Design Matrix (BIDM). The results indicate that only 36.84% of Bahraini hospitals incorporate biophilic design in their interiors. The findings also reveal that private hospitals in Bahrain utilize limited biophilic design application methods and primarily rely on the indirect experience of nature, which accounts for 41.9%, whereas the direct experience of nature constituted 21.3% only. Additionally, the results recognize that private hospitals in Bahrain implement biophilic design at rates ranging between 25.0% and 37.5%. The findings indicate that natural light is the most used aspect of the direct experience of nature, while natural color is the most employed aspect of the indirect experience of nature. The thesis proposes recommendations at policy level to raise awareness on the benefits of biophilic design and encourage the adoption of this approach in healthcare facilities in Bahrain. In addition, it suggests biophilic design solutions that can accommodate the nature of hospitals in Bahrain and their required hygienic and safety regulations. It also makes recommendations for further research to explore different E dimensions of biophilic design in built environments. Ultimately, the thesis calls for enhancing the application of biophilic design in Bahraini hospitals to create healing environments that promote health and well-being.
