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

Durack - Marlow Lagoon averaged approximately 9 new dwelling approvals annually over the past five financial years, with a total of 49 homes approved between FY21 and FY25. In FY26, up to 13 homes have been approved so far. On average, around 2.3 people moved to the area per new home constructed during these five financial years, reflecting strong demand that supports property values.

New homes are being built at an average expected construction cost of $300,000 each. This year, $1.1 million in commercial approvals have been registered, indicating limited commercial development activity compared to previous periods. When compared to Greater Darwin, Durack - Marlow Lagoon shows significantly reduced construction levels, with 50.0% below the regional average per person. This constrained new construction typically reinforces demand and pricing for existing dwellings, although development activity has increased recently. Recent construction comprises 38.0% detached houses and 62.0% attached dwellings, marking a shift from the area's current housing composition of 96.0% houses. The estimated population per dwelling approval is 347 people, indicating a quiet, low activity development environment. According to AreaSearch's latest quarterly estimate, Durack - Marlow Lagoon is forecasted to gain 891 residents by 2041.

If current construction levels persist, housing supply may lag behind population growth, potentially intensifying buyer competition and supporting price growth.
