Every business owner asks the same question first when planning a new workspace:
How much will the office fitout cost?
It is the most important factor in your decision making process. The cost determines your strategy, whether you are moving into an all new building in Gosford or renovating an existing space on the Central Coast. In the Australian market, costs fluctuate heavily based on the building grade (premium, A, or B) and the level of finish you require.
A clear budget is your best tool against scope creep and project delays. When planning a commercial fit out, clients who start with a solid financial strategy stay away from surprise costs associated with construction.
Below is a detailed breakdown of commercial office fitout costs for 2026 to help you plan your next move.
The Cost Breakdown: Understanding the Numbers
How much does an office fitout cost in Australia?
The total investment for an office fitout varies based on the starting point of your building. In the construction industry, we generally categorise these starting points into three tiers: Shell & Core, Cat A, and Cat B.
Shell & Core refers to a building with concrete floors and exposed ceilings but no services. Cat A usually includes basic mechanical and electrical services like lighting and air conditioning grids. Cat B is the move in ready state which includes partitioning, branding, and functional kitchen fitouts or kitchenettes.
You might look at a total spend anywhere from $60,000 to over $500,000 based on the floor plate size for a standard commercial project in 2026. The biggest variable is not always the materials but the condition of the existing services. If we need to upgrade the air conditioning or fire systems to meet current Australian standards, your base fitout cost will rise before we even build a single wall.
What is the average office fitout cost per m² for a standard commercial space?
The most reliable way to estimate your budget early on is to calculate the average office fitout cost by square metre (m²). In our experience across New South Wales, the gap between a budget friendly refresh and a high end corporate headquarters is significant.
What you can expect to pay in the 2026 market based on the level of finish is:
Australia Fit Out Cost Guide: 2026 Pricing per m²
Fitout Tier | Estimated Cost (per m²) | Best For | Key Features |
Basic Fitout | $800 – $1,200 | Startups & Short-term Leases | Retains existing floors/ceilings; simple flat pack workstations; minimal partitioning. Focuses on cost-efficiency over privacy. |
Mid-range Fitout | $1,200 – $2,200 | Established SMEs | Glazed partitions for meeting rooms, upgraded carpet/vinyl mix, custom reception joinery, and enhanced electrical fit out provisions for data and power. |
Premium Fitout | $2,500 – $3,500+ | Corporate HQ & Law Firms | Bespoke architectural joinery, designer finishes, smart lighting, and full kitchen facilities with stone benchtops and high-end AV. |
Are there specific costs associated with an electrical fit out?
Yes. The electrical fit out is often the most underestimated component of the budget. It is not just about the power points; it is about the backbone of your business operations.
Modern offices require robust data cabling (Cat 6 or Cat 6A) to support high-speed internet and cloud-based operations. You must also budget for server room cooling. Standard air conditioning often cannot handle the heat load of a dedicated server rack; there has to be a separate split system.
Then there is lighting. Energy-efficient LED panels or architectural feature lighting can replace outdated fluorescent tubes, which will increase upfront costs but reduce energy bills. Smart-office automation, such as sensor lights and automated blinds, will also push the price higher but offers long-term operational savings.
Does a warehouse fit out cost more than a standard office?
Generally, a warehouse fit out costs less per square metre than a corporate office, typically landing in the $800–$1,500 per m² range. However, the nature of the cost is different.
In a warehouse, we prioritise industrial durability over aesthetics. You are paying for high-bay lighting, three-phase power upgrades, and heavy-duty concrete sealing rather than plush carpets.
The exception is when we install a mezzanine floor to create office space within the warehouse. Structural steelwork for mezzanines is a significant expense, but it effectively doubles your usable floor area without increasing your rent. It makes fitout solutions in industrial spaces are highly cost-efficient in the long run despite the initial capital outlay for structural work.
Factors Influencing Fitout Costs
There are several invisible variables that can impact your interior office fit out budget. Being aware of these early helps us mitigate risks.
Building Condition
Are we starting from scratch or starting from where someone else left off? Leases that have “make good” clauses (which obligate the tenant to return the property to its original or agreed-upon condition upon lease expiry) usually indicate that the previous tenant stripped the space back to basics, which is great. But if we need to demolish existing walls or relocate fire sprinkler heads, your construction fit out labour costs will increase. Older buildings on the Central Coast may also have outdated electrical switchboards that need upgrading to handle modern power loads.
Technology Integration
The cost of AV (audio-visual) and connectivity is rising. Boardrooms now demand integrated video conferencing systems rather than just a projector. High-speed connectivity requires structured cabling and dedicated pathways. If your team relies on a wireless-first environment, we need to install enterprise-grade Wireless Access Points (WAPs) throughout the ceiling grid so that there are no dead zones.
Custom Joinery
There is a huge price difference between buying a reception desk from a supplier and having one custom-built. Custom joinery allows for branding integration and perfect sizing, but it requires skilled cabinet makers and premium materials like stone or Corian. Flat-pack solutions are cheaper but offer fewer durability and aesthetics factors.
Compliance and Approvals
You cannot ignore red tape. Commercial office fitout costs must include fees for Complying Development Certificates (CDC) or Development Applications (DA). We also need to factor in accessibility compliance (AS1428.1), for ramps, tactile indicators, and doorways to meet Australian Standards. Local regulations, such as those from the Central Coast Council, may impose specific waste management or fire safety requirements that influence the build.
Australia Fit Out Cost Guide: Budgeting Tips
Advise on contingency funds
Always set aside a contingency fund of 10% to 15% of your total project value. Construction is unpredictable. We might open a wall and find structural issues, or material shipping delays could require expedited freight. This buffer makes sure that a small hiccup does not halt the entire project.
The value of a construction fit out specialist
It might be tempting to hire a general handyman for small changes, but a dedicated construction fit out specialist saves you money long-term. We understand the specific sequence of trades required for commercial projects. A generalist might paint the walls before the electrician has finished wiring, leading to patching and repainting. Specialists deliver efficiency and a structural warranty that protects your investment.
Sustainable office solutions
The investment in sustainability reduces long-term operational costs. Motion-sensor lighting, water-efficient fixtures, and thermal insulation might cost more upfront but pay for themselves through lower utility bills. Plus, many Australian employees now expect an environmentally conscious workplace.

How much does an office fitout cost?
In 2026, a typical fitout ranges from $60,000 for small suites to over $500,000 for larger floors, varying heavily based on the existing building condition and design complexity.
What is the average office fitout cost per m² for a standard commercial space?
Budget fitouts typically cost $800–$1,200 per m², mid-range projects sit between $1,200 and $2,000 per m², and premium designs generally exceed $2,000 per m².
Are there specific costs associated with an electrical fit out?

Does a warehouse fit out cost more than a standard office?
Usually no. Warehouse fitouts are generally cheaper per square metre ($800 – $1,500) due to simpler finishes, though costs increase if structural mezzanines or heavy-duty power upgrades are required.
Stop Estimating and Start Planning the Next Move
