For areas not covered by this data, NSW State Government's SA2 level projections from 2022 (base year 2021) are used. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population dynamics suggest a median increase, with Harrington Park expected to grow by 740 persons by 2041, reflecting a total increase of 6.4% over the 17-year period based on latest annual ERP population numbers.

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, 66 homes were approved, with an additional 3 approved so far in FY26. Each dwelling built over these years has resulted in an average 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, $50,000 in commercial development approvals have been recorded, reflecting the area's residential nature. Compared to Greater Sydney, Harrington Park has significantly lower building activity, at 74.0% below the regional average per person. This scarcity of new homes typically boosts demand and prices for existing properties. Nationally, this is also below average, suggesting the area's maturity and possible planning constraints.

All new construction in Harrington Park consists of detached dwellings, preserving its suburban character and attracting space-seeking buyers. With around 2468 people per dwelling approval, it reflects a highly mature market. Population forecasts indicate Harrington Park will gain 737 residents by 2041, according to the latest AreaSearch quarterly estimate. Building activity is keeping pace with growth projections, but buyers may face increased competition as the population grows.
