Western Australia has a cost multiplier of +5% compared to the national average. Key factors include:
Clearly define scope before requesting quotes
Ask for fixed-fee quotes where possible
Bundle related services (e.g., architect + engineer)
Provide all relevant documents upfront to reduce billable time
Not always. For minor renovations, a building designer or draftsperson may suffice. For complex projects, heritage properties, or large extensions, an architect adds significant value and may be required by council.
Quantity surveyors prepare cost estimates, tax depreciation schedules, and insurance valuations. For investment properties, a depreciation schedule typically costs $500–$800 and can save thousands in tax deductions.
