Project homes, which utilise standardised designs and materials, offer a more predictable cost structure. Custom builds, on the other hand, provide design flexibility but come with a higher price tag due to unique architectural requirements and bespoke material selections.

According to industry bodies like the Housing Industry Association (HIA) and Master Builders Australia (MBA), average construction costs continue to rise. This is driven by labour shortages, material price fluctuations, and increased regulatory compliance.
