Public hospitals tend to be overcrowded, creating a higher need for patients to have access to a place where they can de-stress and heal their psyches. As hospitals around the world are increasingly adopting a patient-centred care model, they are also finding new ways to incorporate care into the built environment. One of the fastest growing trends is the installation of green roofs, or roof gardens, to create tranquil oases on otherwise barren rooftop spaces. In this research, with regard to benefits and advantages of roof gardens and healing gardens, the integration of these two gardens in the rooftop of the hospitals can contribute to the health problems of the patients as well as providing ecological profits and ecosistem services. In this research, with the analysis and survey of some hospital roof gardens, it has been attempted to discover the specific design qualities and features of these gardens.
