Measure in square metres

The Australia preset uses square metres. Measure the project area accurately and separate rooms with very different complexity. A bathroom, kitchen, deck, roof, or paint project should not be compared using floor area alone.

Local market factors

Renovation quotes can be affected by trade availability, city demand, travel time, parking, disposal, approvals, site access, and material lead times. These can matter as much as finish level.

Questions to ask contractors

  • Are approvals, inspections, and waste removal included?
  • Which materials are fixed and which are allowances?
  • How are delays or substitutions handled?
  • Is site protection and cleanup included?

Calculator settings to adjust

Select Australia, measure in square metres, choose the region closest to your market, and adjust contingency or local market settings based on early contractor feedback.

FAQ

Can the calculator provide exact Australian renovation costs?

No. It provides planning estimates that must be checked against local quotes.

Why should I separate rooms by project type?

Different rooms use different trades and materials, so a single square-metre rate can hide large cost differences.

Next steps

Start with the calculator, save your range, and request quotes using the same scope and material assumptions. The more specific your scope is, the easier it becomes to compare bids fairly.
