Default scenario: 70 m². Use the calculator for your actual project.
Mackay budgets are affected by cyclone standards, humidity and changing labour demand from nearby resource activity. Structural strengthening, roof removal, stair design, scaffolding and weather protection make building up more complex. Compare the low, central and high ranges instead of relying on one false-exact figure.
For a second-storey addition in Mackay, record the measured quantity, retained items, demolition, access, services, approvals, fixtures and finish level before comparing alternatives. This helps separate genuine local price differences from businesses pricing different scopes.
For Mackay planning, use the central result as a working allowance and keep the upper range visible until existing conditions, structural requirements, long-lead selections and approval costs are confirmed. The 1.05× location factor is only one input, so review the full cost breakdown and free PDF before setting the final second-storey addition budget.
Write down demolition, retained items, service moves, finishes, approvals and exclusions so every comparison covers the same work.
Track provisional sums and prime-cost items separately. These are common sources of budget movement after work starts.
Keep the difference between the central and high estimate visible until access, structure and concealed conditions are confirmed.
