Adelaide Heritage Character Areas and Hot Climate Construction
Adelaide's inner ring heritage character areas (Unley, Norwood Payneham and St Peters, Prospect, Glenelg) have significant restrictions on new builds and alterations, character design controls require new homes to be sympathetic to the street's architectural character. These areas often prohibit demolishing existing character homes. Adelaide's hot climate also creates specific building design requirements for passive cooling, orientation, eave depth, window shading, and thermal mass are critical design considerations for Adelaide homes that will perform well in 40°C+ summer heatwaves. cbs.sa.gov.au
