An office fitout in Australia typically costs between $500 and $3,000 or more per square metre, depending on fitout tier, space condition, and project scope. A basic open-plan fitout for a small commercial tenancy sits at the lower end. A fully specified, high-end corporate environment with custom joinery, integrated technology, and premium finishes pushes well beyond that range. Understanding where your project sits within that spectrum — and what drives the difference — is the foundation of any realistic fitout budget.
What Does an Office Fitout Cost in Australia?
Office fitout costs in Australia vary widely based on the level of finish, the condition of the existing space, and the complexity of the brief. As a general guide, fitout pricing falls into three tiers: budget, mid-range, and premium. Each tier reflects a different combination of materials, trades, and design intent — and each carries a different per-square-metre cost.
Base-Level Fitout Costs (Budget Tier)
A budget office fitout typically costs between $500 and $1,000 per square metre. This tier suits businesses fitting out a space that already has functional services — existing lighting, basic HVAC, and compliant amenities. Work at this level generally covers carpet or vinyl flooring, painted plasterboard partitions, standard workstations, and minimal joinery. It is common for small tenancies, short-term leases, or businesses prioritising function over brand expression. For a 200 sqm office, a budget fitout could range from $100,000 to $200,000 before contingency.
Mid-Range and Premium Fitout Costs
Mid-range fitouts typically cost between $1,000 and $2,000 per square metre and introduce higher-quality finishes, purpose-built meeting rooms, acoustic treatment, and more considered lighting design. Premium fitouts — those targeting corporate headquarters, professional services firms, or design-led environments — regularly exceed $2,000 to $3,000+ per square metre. At this level, custom joinery, integrated AV systems, feature ceilings, and high-specification flooring are standard. A 500 sqm premium fitout can comfortably reach $1.5 million or more before FF&E and technology procurement.
Understanding the cost ranges is only part of the picture. How you scope and plan the project determines whether your budget holds through to practical completion or erodes under the weight of unplanned variations.
What Factors Influence Office Fitout Costs?
Several variables move fitout costs up or down independently of finish level. Knowing these factors before you commit to a budget prevents the most common planning mistakes.
Space Size, Condition, and Configuration
Larger spaces benefit from economies of scale — the cost per square metre varies significantly between a 100 sqm tenancy and a 1,000 sqm floor plate. Equally important is the condition of the base build. A space delivered as a warm shell — with services roughed in and concrete floors exposed — costs more to fitout than a space with existing partitions, ceiling grids, and functional amenities. Irregular floor plates, structural columns, and poor natural light also add cost by requiring design solutions that a straightforward rectangular space does not.
Fitout Scope — Partitions, Joinery, and Services
The scope of work is the single largest cost variable. A fitout that requires new hydraulics, upgraded electrical capacity, or full HVAC replacement carries a fundamentally different cost structure than one that reuses existing services. Partitioning systems, joinery, and specialist rooms — server rooms, boardrooms, wellness spaces — each add cost in proportion to their specification. Every item added to the scope is a cost decision, not just a design one.
Hidden Costs That Blow Office Fitout Budgets
Budget overruns are rarely random — they follow predictable patterns that experienced fitout contractors recognise immediately. The most common hidden costs include building owner consent fees, make-good obligations at lease end, authority approvals, and asbestos or hazardous material remediation in older buildings. Builders’ preliminaries, project management fees, and consultant costs — architects, engineers, certifiers — are frequently underestimated or excluded from early budget estimates. A contingency allowance of 10 to 15 percent of the total construction budget is not conservative; it is standard practice on any fitout where the base build condition has not been fully investigated.
Conclusion
Office fitout costs in Australia range from $500 to $3,000+ per square metre, shaped by fitout tier, space condition, and project scope. Budget accurately and the number is manageable. Underestimate the variables and costs compound quickly.
Homeowners, investors, and business owners who plan fitouts with a clear scope, realistic contingency, and an experienced contractor consistently achieve better outcomes — on budget and on schedule.

Frequently Asked Questions
How long does an office fitout take in Australia?
A standard office fitout takes between 6 and 16 weeks depending on scope, size, and approval requirements. Complex or large-scale fitouts with significant services work can extend beyond that timeline.
What is included in an office fitout?
An office fitout typically includes partitioning, flooring, ceiling systems, lighting, joinery, electrical and data, HVAC, and amenities fit-out. The exact scope depends on the base build condition and the client brief.
Can I reduce office fitout costs without sacrificing quality?
Yes. Prioritising flexible, open-plan layouts, reusing existing services where compliant, and selecting mid-range finishes in low-traffic areas are proven strategies for reducing cost without compromising the overall result.
Do I need council approval for an office fitout in Australia?
Most commercial fitouts require a Development Application or Complying Development Certificate, depending on the scope and local council requirements. Your fitout contractor or certifier can confirm the correct approval pathway early in the process.
What is the difference between a base build and a fitout?
A base build is the landlord’s delivery of the shell — structure, core services, and building envelope. A fitout is the tenant’s work to make that shell functional and fit for purpose, including partitions, finishes, joinery, and fit-for-use services.
