AreaSearch analysis of residential development drivers sees Gordon - Killara recording a relatively average level of approval activity when compared to local markets analysed countrywide

Gordon-Killara has experienced approximately 47 dwelling approvals annually over the past five financial years, totalling 236 homes. As of FY-26, there have been 31 recorded approvals. On average, each dwelling built between FY-21 and FY-25 has gained around 2.9 new residents per year, indicating strong demand that supports property values. New homes are being constructed at an average expected cost value of $705,000, targeting the premium market segment with higher-end properties.

The location has approximately 815 people per dwelling approval, indicating an established market. According to the latest AreaSearch quarterly estimate, Gordon-Killara is expected to grow by 2,412 residents through to 2041.
