AreaSearch assessment of residential development drivers sees a low level of activity in Harrington Park, placing the area among the bottom 25% of areas assessed nationally

Harrington Park has averaged approximately 13 new dwelling approvals per year. Over the past five financial years, from FY21 to FY25, a total of 66 homes were approved, with an additional 4 approved so far in FY26. Each dwelling built over these five years has resulted in an average gain of 2.6 new residents annually, indicating strong demand that supports property values.

The average expected construction cost value for new homes is $404,000. This financial year has seen $50,000 in commercial development approvals, reflecting the area's residential nature. Compared to Greater Sydney, Harrington Park records significantly lower building activity, at 74.0% below the regional average per person. This scarcity of new homes typically strengthens demand and prices for existing properties. Nationally, this figure is also below average, suggesting the area's maturity and possible planning constraints.

All new construction has been comprised of detached dwellings, preserving Harrington Park's suburban nature with an emphasis on detached housing attracting space-seeking buyers. With around 2468 people per dwelling approval, Harrington Park reflects a highly mature market. According to AreaSearch's latest quarterly estimate, Harrington Park is forecasted to gain 586 residents by 2041. Building activity appears to be keeping pace with growth projections, though heightened competition among buyers may arise as the population grows.
