For areas not covered, NSW State Government's SA2 level projections are used, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population dynamics anticipate a significant increase, with the suburb expected to grow by 4,565 persons to 2041 based on aggregated SA2-level projections, reflecting an overall increase of 14.0% over the 17 years.

The level of residential development activity in Denham Court was found to be higher than 90% of real estate markets across the country

AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Denham Court averaged approximately 256 new dwelling approvals per year over the past five financial years, totalling an estimated 1,281 homes. As of FY-26, 31 approvals have been recorded. Between FY-21 and FY-25, an average of 5.6 new residents arrived per dwelling constructed annually, indicating demand outpacing supply and potential upward pressure on prices and increased competition among buyers. New homes are being built at an average expected construction cost value of $576,000, targeting the premium market segment with higher-end properties.

This financial year has seen $3.9 million in commercial approvals registered, suggesting limited focus on commercial development. Current development consists of 89.0% detached dwellings and 11.0% townhouses or apartments, maintaining Denham Court's suburban identity with a concentration of family homes suited to buyers seeking space.

The area has approximately 295 people per dwelling approval, indicating room for growth.
