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 seen approximately 47 dwellings receive development approval annually over the past five financial years, totalling 236 homes. As of FY-26, 28 approvals have been recorded. On average, each dwelling built between FY-21 and FY-25 attracted 2.9 new residents per year, indicating strong demand which may support property values. New homes are being constructed at an average cost of $705,000, suggesting developers target the premium market segment with higher-end properties.

This financial year, $114.7 million in commercial approvals have been registered, reflecting high local commercial activity. Compared to Greater Sydney, Gordon-Killara records roughly half the building activity per person and ranks among the 18th percentile of areas assessed nationally, suggesting limited buyer options but strong demand for established dwellings. This lower activity may reflect market maturity or potential development constraints. New development consists of 71.0% detached houses and 29.0% townhouses or apartments, maintaining the area's suburban character with a focus on detached housing attracting space-seeking buyers.

The location has approximately 815 people per dwelling approval, indicating an established market. According to AreaSearch's latest quarterly estimate, Gordon-Killara is expected to grow by 2,415 residents by 2041. At current development rates, housing supply may struggle to match population growth, potentially intensifying buyer competition and supporting price increases.
