Recent residential development output has been above average within Baulkham Hills when compared nationally

Between FY-21 and FY-25, an estimated 681 homes were approved, with a further 46 approved so far in FY-26. Over these five years, on average, 1.5 people moved to the area for each dwelling built.

This suggests balanced supply and demand, creating stable market conditions. New properties are constructed at an average value of $623,000, indicating focus on premium developments.

Recent construction comprises 44.0% standalone homes and 56.0% medium to high-density housing, marking a significant shift from the current 75.0% houses.

This trend may be due to diminishing developable land availability and evolving lifestyle preferences. Baulkham Hills has around 326 people per dwelling approval, indicating low density characteristics. Population forecasts suggest Baulkham Hills will gain 4,261 residents by 2041. At current development rates, new housing supply should meet demand comfortably, providing good conditions for buyers and potentially supporting growth beyond current population projections.
