It is expected that there will be more heat waves, floods, bush fires, coastal erosion and drought. Unfortunately, Australia is vulnerable to climate change due its hot and dry climate and as the driest state; changes are already being felt in South Australia. There is an urgent need to start adapting to climate change to cope with present and predicted climate change in the future by changing or adjusting building regulations, land use plans, and land subdivision regulations. This paper aims to provide design guidelines for adaptation to climate change at the neighborhood level. A case study method was adopted to achieve the aim of this paper. The study was conducted in two stages. The first stage presents the current design of neighborhood and its adopted design parameters for climate change. The second part provides the design guidelines for adaptation to climate change at the neighborhood level. The case study has a well oriented grid iron layout that serves as the basis of orienting and sitting future buildings that can adapt to climate change. However, the orientation of roads is good, it will be necessary to reconfigure elements of landscaping and built environment in order to address climate change in built environment by modifying design elements.展开更多
