AreaSearch assessment of residential approval activity sees Rossmoyne among the top 30% of areas assessed nationwide

Based on AreaSearch analysis using ABS building approval numbers from statistical area data, Rossmoyne averaged approximately 36 new dwelling approvals annually over the past five financial years, totalling an estimated 181 homes. As of FY-26 so far, 14 approvals have been recorded. Each year, on average, around 2.2 new residents per dwelling built were gained between FY-21 and FY-25, indicating robust demand that supports property values. New homes are being constructed at an average expected construction cost value of $610,000, suggesting a focus on the premium market with high-end developments.

In this financial year, $634,000 in commercial development approvals have been recorded, indicating minimal commercial development activity. Compared to Greater Perth, Rossmoyne shows 88.0% higher building activity per person, offering buyers greater choice, though recent periods have seen a moderation in development activity. New building activity comprises 96.0% standalone homes and 4.0% attached dwellings, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. Notably, developers are building more traditional houses than the current mix suggests (79.0% at Census), indicating continued strong demand for family homes despite density pressures.

The location has approximately 133 people per dwelling approval, suggesting an expanding market. According to AreaSearch's latest quarterly estimate, Rossmoyne is expected to grow by 776 residents through to 2041.
