For areas not covered by this data, NSW State Government's SA2 level projections are used, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041.

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 dwelling approvals annually over the past five financial years, totalling 236 homes. As of FY-26, 90 approvals have been recorded. On average, each dwelling built between FY-21 and FY-25 attracted around 2.9 new residents per year, indicating strong demand that supports property values. New homes are constructed at an average cost of $705,000, targeting the premium market segment with higher-end properties.

This financial year has seen $114.7 million in commercial approvals, 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 nationally, suggesting limited buyer options while boosting demand for established dwellings. This lower activity is indicative of market maturity and possible development constraints. New development consists predominantly of detached houses (71.0%) with townhouses or apartments making up the remainder (29.0%), preserving the area's suburban character and attracting space-seeking buyers.

The location has approximately 815 people per dwelling approval, demonstrating an established market. Looking ahead, Gordon Killara is projected to grow by 2,249 residents by 2041. At current development rates, housing supply may struggle to meet population growth, potentially intensifying buyer competition and supporting price increases.
