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

AreaSearch analysis of ABS building approval data for Leppington shows approximately 458 new homes approved annually. Over the past five financial years, from FY-21 to FY-25, around 2,293 homes were approved, with an additional 134 approved in FY-26 so far. Each year, on average, 3.1 people move to the area for each dwelling built during these five years.

This high demand outpaces supply, potentially driving up prices and increasing competition among buyers. The average construction value of new properties is $523,000, indicating a focus on premium developments. In FY-26, commercial approvals totaled $34.6 million, suggesting strong local business investment. Comparing Leppington to Greater Sydney, building activity per person is 154.0% higher, offering buyers more choice but showing a recent slowdown in activity. This high level of activity reflects developers' confidence in the location.

Most new developments are detached dwellings (91.0%), maintaining the area's low-density character and appealing to families seeking space. There are approximately 48 people per dwelling approval, indicating an expanding market. Population forecasts estimate Leppington will gain 31,787 residents by 2041. If current construction levels continue, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.
