Residential development activity is lower than average in Alexander Heights - Koondoola according to AreaSearch's national comparison of local real estate markets

Over the past five financial years, from FY-21 to FY-25, around 138 homes were approved, with another 13 approved so far in FY-26.

New homes are being constructed at an average expected cost of $192,000, which is lower than regional levels, suggesting more affordable housing options for buyers. This year alone, around $1.9 million in commercial approvals have been registered, reflecting a predominantly residential focus in the area. Compared to Greater Perth, Alexander Heights - Koondoola has significantly less development activity, with 80.0% below the regional average per person. This constrained new construction typically reinforces demand and pricing for existing dwellings. Similarly, when compared nationally, the area reflects market maturity and potential development constraints.

The majority of new building activity consists of detached houses (85.0%), with medium and high-density housing making up the remaining 15.0%, sustaining the area's suburban identity and attracting buyers seeking space. With around 445 people per dwelling approval, Alexander Heights - Koondoola indicates a developed market. According to population forecasts, the area is expected to gain approximately 288 residents by 2041.
