AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024, with 2022 as the base year. For areas not covered by this data, NSW State Government's SA2 level projections released in 2022 are used, with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, Harrington Park is expected to grow by 1,008 persons, reflecting a gain of 7.6% over the 17-year period.

Residential development activity is lower than average in Harrington Park according to AreaSearch's national comparison of local real estate markets

Harrington Park has recorded approximately 16 residential properties granted approval per year. Over the past five financial years, from FY21 to FY25, around 81 homes were approved, with a further 6 approved in FY26 so far. On average, about 4.7 people have been moving to the area annually for each dwelling built over these five years.

This high demand relative to supply typically puts upward pressure on prices and intensifies competition among buyers. The average expected construction cost value of new dwellings is $478,000, aligning with regional patterns. In FY26, there have been $50,000 in commercial approvals, indicating the area's residential nature. Compared to Greater Sydney, Harrington Park has significantly less development activity, at 73.0% below the regional average per person. This constrained new construction often reinforces demand and pricing for existing properties.

The area also falls under the national average for development activity, suggesting its established nature and potential planning limitations. New development consists predominantly of detached dwellings (86.0%) with a smaller proportion of attached dwellings (14.0%), maintaining Harrington Park's suburban identity with a focus on family homes. The location has approximately 1180 people per dwelling approval, indicating an established market. According to AreaSearch's latest quarterly estimate, Harrington Park is projected to gain 1,034 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.
