Understanding Commercial Fit-Out Costs per Square Metre

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Commercial fit-out costs in Australia can range from $600 to $2,500 per square metre, depending on factors like location, design complexity, and quality of finishes. It's crucial to consult professionals for accurate budgeting and compliance with all regulations.

Determining the cost of a commercial fit-out per square metre in Australia involves multiple factors, including the type of business, location, and the quality of materials used. On average, these costs can range from $600 to $2,500 per square metre. This wide range reflects the diversity in fit-out requirements across different industries, from basic office spaces to high-end retail environments.

Under the umbrella of construction costs, a commercial fit-out includes alterations to the interior of a building to meet the specific needs of a business. This can range from simple partitions and flooring to complex electrical and HVAC systems. The most common misconception is that fit-out costs are similar across all types of commercial spaces, but factors such as local building codes, the need for specialised installations, and aesthetic requirements can significantly affect pricing.

Take a practical example of a medium-sized office in the Sydney CBD. Suppose the office space is 200 square metres, and the fit-out involves mid-range finishes and standard office requirements, including partitions, carpeting, and basic electrical work. At a mid-range cost of $1,200 per square metre, the total fit-out cost would be $240,000. For a business owner at a 37% marginal tax rate, this investment could potentially reduce taxable income by a significant amount through depreciation over time.

In our experience reviewing thousands of properties across Australia, one pattern stands out: businesses often underestimate the impact of local regulations and the need for bespoke solutions in their fit-outs. Overlooking these can lead to costly retrofits or compliance issues. Another common oversight is underestimating the impact of technology integration, which can significantly inflate costs if not planned from the outset.

The answer can differ depending on your situation. For example, fit-outs in heritage-listed buildings are often more expensive due to preservation requirements. Similarly, high-end retail fit-outs in premium locations may exceed the upper range due to the need for luxury finishes and bespoke designs. If your business is in a shared or co-working space, costs may be lower as some infrastructure is already in place.

Given the complexity and variability of commercial fit-out costs, engaging a Chartered Quantity Surveyor can provide clarity and accuracy in your budgeting process. A professional can help navigate the nuances of local regulations, optimise the design to suit your business needs, and ensure compliance with all statutory requirements.

  • Assess Your Needs: Determine the specific requirements of your business and the desired quality of finishes.
  • Consult Professionals: Engage a Chartered Quantity Surveyor and an architect to develop a realistic budget.
  • Obtain Approvals: Ensure all necessary permits and regulatory approvals are in place before commencing work.
  • Plan for Contingencies: Allocate a contingency budget to cover unexpected costs.
  • Review Contracts Carefully: Ensure all contracts with builders and suppliers are clear and comprehensive.
  • Monitor Progress: Regularly review the progress of the fit-out to stay on budget and schedule.
