Gordon-Killara has seen approximately 47 dwelling developments approved annually. The Australian Bureau of Statistics (ABS) reports that between financial years FY21 and FY25, around 236 dwellings were approved, with 3 approvals so far in FY26. On average, each dwelling built over the past five financial years has attracted 2.9 new residents annually, indicating strong demand for housing.

In this financial year, commercial approvals amount to $114.7 million, reflecting significant local commercial activity. Compared to Greater Sydney and nationally, Gordon-Killara records lower building activity per person, placing it in the 19th percentile of areas assessed, indicating limited new buyer options but robust demand for established dwellings.

The population density is approximately 815 people per dwelling approval, indicating a well-established market.

By 2041, Gordon-Killara is projected to grow by 2,415 residents. Given current development rates, housing supply may struggle to keep pace with population growth, potentially intensifying buyer competition and supporting property price increases.
