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 received around 47 dwelling approvals annually over the past five financial years, totalling 236 homes. As of FY-26, there have been 19 approvals recorded. Over these years, an average of 2.9 new residents were gained per dwelling built, indicating strong demand that supports property values. New homes are being constructed at an average cost of $1,319,000, targeting the premium market segment with higher-end properties.

This financial year has seen $114.7 million in commercial approvals registered, reflecting high local commercial activity. Compared to Greater Sydney, Gordon-Killara records roughly half the building activity per person and ranks among the 19th percentile nationally for assessed areas, suggesting limited buyer options while strengthening demand for established dwellings. This lower activity reflects market maturity and possible development constraints. New development consists of 71.0% detached houses and 29.0% townhouses or apartments, preserving the area's suburban nature with a focus on detached housing attracting space-seeking buyers.

The location has approximately 815 people per dwelling approval, demonstrating an established market. Looking ahead to 2041, Gordon-Killara is expected to grow by 2,415 residents. At current development rates, housing supply may struggle to match population growth, potentially increasing buyer competition and supporting price increases.
