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

AreaSearch analysis of ABS building approval data indicates Thornbury averaged approximately 56 new dwelling approvals annually over the past five financial years, totalling an estimated 281 homes. As of FY-26, 48 approvals have been recorded. Between FY-21 and FY-25, an average of 0.9 new residents per year was associated with each dwelling constructed. This suggests that new construction is meeting or exceeding demand, providing more options for buyers and potentially driving population growth beyond current projections.

The average expected construction cost value of new properties in Thornbury is $717,000, indicating a focus on the premium segment by developers. In FY-26, commercial approvals totalled $43.9 million, reflecting high levels of local commercial activity. Compared to Greater Melbourne, Thornbury has 16.0% fewer new developments per person. Nationally, it ranks at the 35th percentile among assessed areas, suggesting more limited housing choices for buyers and supporting demand for existing dwellings. This is also below the national average, implying an established market with potential planning constraints.

Current building activity comprises 40.0% standalone homes and 60.0% attached dwellings, indicating a trend towards denser development that caters to downsizers, investors, and entry-level buyers. With around 474 people per dwelling approval, Thornbury exhibits characteristics of a developed market. AreaSearch's latest quarterly estimate projects Thornbury will add approximately 7,312 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and driving price increases.
