Botanic gardens, valued for their live plant collections, have evolved into scientific institutions with roles in conservation, education, research, and public recreation. This study repositions botanic gardens as essential urban habitats enhancing biodiversity, focusing particularly on their support for both European honeybees and Western Australian native bees. This research addresses the intersection of urbanisation and bee conservation by developing a conceptual design for a bee-friendly botanic garden in Yanchep, Western Australia. It employs semi-structured interviews and research through design (RtD) methods to collaborate with local beekeepers, landscape architects, and ecologists. A systematic design framework for a bee-friendly botanic garden in Yanchep, Western Australia was proposed, encompassing the entire design process, from scope to detailed considerations, and aiming to be applicable across other parts of Western Australia and Australia. The research highlights three key findings: the necessity of interdisciplinary collaboration, the importance of defining the garden type and functions early in the design process, and the need for diverse plant selection and nesting options to support native bees.
