Office fitout cost is one of the first numbers a tenant asks for and one of the hardest to answer honestly. A square metre rate from a published guide gives you a starting point, and nothing more.
Two tenancies of the same size in the same building can finish tens of thousands of dollars apart depending on what is already in the ceiling, how many rooms the plan calls for, what the landlord requires, and when the builder is allowed on site. This guide explains what a fitout actually covers, where the money goes, and the factors that decide whether your budget holds or not.
Understanding your office fitout cost is essential for budgeting effectively. The office fitout cost can vary significantly based on various factors, so it’s crucial to have a clear estimate.
What a fitout covers, and what it does not
When considering your office fitout cost, it’s important to factor in both the essential components and the additional features that can enhance your workspace.
The overall office fitout cost will depend on the specific requirements outlined in your lease agreement, making it essential to review these details thoroughly.
A fitout is the work that turns a bare tenancy into a space a business can operate from.
In an office, that means partitions, ceilings, floor finishes, joinery, lighting, power and data, supplementary air conditioning, meeting rooms, and the kitchen.
In a retail tenancy, it adds the shopfront, signage, display joinery, back-of-house areas, and any specialist services the trade needs, such as grease arrestors, exhaust, or cold rooms.
What a fitout does not include is the base building.
The structure, lifts, main plant, fire sprinklers to the tenancy boundary, and the building services capped off at the tenancy are the landlord’s responsibility.
The line between the two is set by the lease and the landlord’s tenancy fitout guide, and it moves from building to building.
A tenancy handed over as a “cold shell” with no ceiling, no services, and a raw slab costs far more to fit out than one handed over with a ceiling, lighting, and air conditioning already in place.
Reading that handover condition before you price anything is the first step in any credible estimate.
Ultimately, the office fitout cost reflects not only the physical changes made but also the vision and functionality desired in your new space.
Different components contribute to your overall office fitout cost, and being aware of these can assist you in planning appropriately.
Your office fitout cost is influenced by your choice of materials, technology, and the extent of customization required for the space.
Where the money goes
It’s vital to consider how each decision you make impacts the overall office fitout cost to ensure your project stays within budget.
Fitout budgets tend to be pictured as furniture and finishes. In practice most of the money sits in the building work and the services behind the walls and above the ceiling. JLL’s Australia and New Zealand Fit-Out Cost Guide 2026 puts the cost of a medium-quality office fitout in Australia at around AU$3,011 per square metre* and breaks the budget down as follows.
| Cost component | Share of a typical office fitout budget* |
| Builders’ works (partitions, ceilings, floors, joinery, finishes) | About 50%* |
| Mechanical and electrical services | About 20%* |
| Security, IT and audiovisual | About 14%* |
| Furniture, fixtures and equipment | About 11%* |
| Professional services (design, engineering, project management) | About 4%* |
*Figures are drawn from JLL’s Australia and New Zealand Fit-Out Cost Guide 2026, are indicative only, expressed in Australian dollars, and vary with city, building, specification and market conditions. They should not be relied on for budgeting a specific project. An independent estimate prepared from your drawings and the landlord’s tenancy conditions is the only reliable basis for a fitout budget.
Two things stand out in that split. Half the budget is builder’s work, which is the part most affected by how many walls, rooms and finishes the plan contains. And a third of it sits in services and technology, which is the part most affected by what the building already has and what your business needs added. Neither can be priced from a floor area alone.
The factors that drive an office fitout cost
The condition of the tenancy at handover
The design phase greatly influences the office fitout cost, so collaborating with professionals can lead to a better outcome and potentially lower expenses.
This is the single biggest variable and the one most often missed at lease negotiation. If the previous tenant’s fitout is still in place, you may inherit useful ceilings, lighting and partitions, or you may inherit a demolition and make-good bill before your own work starts. If the tenancy is a cold shell, the ceiling grid, lighting, air conditioning distribution and floor coverings all land in your budget rather than the landlord’s. Ask for the tenancy handover condition in writing and have it priced before the lease is signed, not after.
As technology advances, the office fitout cost can also increase, especially with the integration of modern audiovisual systems and smart technology.
Understanding the nuances of your office fitout cost will empower you to make informed decisions throughout the leasing process.
Open plan is cheap to build. Rooms are not. Every meeting room, office and quiet room brings partitions to slab or ceiling, a door, acoustic treatment, its own lighting circuit, its own air conditioning outlet or supplementary unit, and usually its own data and audiovisual points. The shift to hybrid work has pushed the number of meeting and video rooms per floor up, and JLL identifies meeting rooms and technology infrastructure as one of the main pressures on fitout cost in 2026. A plan with twelve enclosed rooms will cost materially more per square metre than one with four, whatever the finishes.
Services capacity and what has to be added
Base building air conditioning is designed for a general open-plan load. Enclosed rooms, dense workstations, server rooms and kitchens add heat that the base system was not designed to remove, so supplementary units, extra ductwork and controls follow. Electrical capacity works the same way: a tenancy distribution board sized for one tenant may not carry the load of another. Fire services almost always move, because sprinkler heads, detectors and exit signage have to match the new layout, and that work is usually restricted to the landlord’s nominated contractor at the landlord’s rates. Hydraulic work is the expensive surprise in office fitouts: a kitchen or extra bathroom that is more than a few metres from an existing riser can mean core drilling, new drainage and after-hours work in the tenancy below.
As technology advances, the office fitout cost can also increase, especially with the integration of modern audiovisual systems and smart technology.
Joinery, finishes and the specification level
Ultimately, understanding the difference between the base building and your fitout can clarify your office fitout cost and ensure accurate budgeting.
Finishes are where a budget is most visible and, oddly, where it is least often blown. The reason is that finishes are easy to see and easy to substitute. A stone reception counter can become laminate; a timber ceiling can become a painted feature bulkhead. The risk in finishes is not the unit rate, it is the quantity. Full-height joinery runs, feature ceilings across the whole floor and integrated planters add up quickly, and they are usually drawn before anyone has costed them.
Technology and audiovisual
Cabling, comms rooms, access control, CCTV, room booking systems, video conferencing and display screens now sit at around one seventh of a typical office fitout budget*. This work is often procured separately from the builder, which means it is also often left out of the headline fitout figure. When comparing quotes, check whether technology is inside the price or a separate allowance to be confirmed later.
The landlord’s rules
Most commercial buildings have a tenancy fitout guide that dictates who can work on the fire, mechanical and building management systems, what hours noisy or disruptive work can be done, how materials get into the building, what protection is required in lifts and lobbies, and what fees the landlord charges for reviewing your design and supervising your works. Each of those adds cost. After-hours work in particular can add a significant premium to trade rates*, and in an occupied building it can apply to demolition, core drilling, fire works and anything involving the lift.
Programme and access
A fitout that has to be delivered inside a fixed lease commencement date, in a building with one goods lift and a shared loading dock, will cost more than the same fitout with a comfortable programme and easy access. Builders price risk, and a compressed programme is risk. So is a lease that only allows works on weekends.
With retail fitouts, the office fitout cost can skyrocket due to the additional branding and customer experience elements that need to be factored in.
Make-good at the end
Most leases oblige the tenant to return the premises to their original condition at expiry. The cost of removing what you are about to build is rarely in the fitout budget, but it is a real cost of the fitout, and a lender or a board will want to see it. An estimate prepared at the start of the lease can put a defensible number against the make-good liability years before it falls due.
Frequently, the office fitout cost can exceed initial estimates if unexpected changes arise during the project, so staying informed is key.
Receiving a detailed breakdown of your office fitout cost from your estimator can help prevent financial surprises down the line.
In conclusion, understanding the nuances of your office fitout cost will empower you to make informed decisions throughout the leasing process.
As you navigate your office fitout cost, remember that investing in quality can lead to long-term savings and enhanced productivity.
Ultimately, understanding the difference between the base building and your fitout can clarify your office fitout cost and ensure accurate budgeting.
What changes for a retail fitout
Your overall office fitout cost will vary depending on the additional features and services specific to your retail needs.
Neglecting to account for certain costs can inflate your office fitout cost, so it’s essential to include all potential expenses in your plan.
Retail fitouts share every driver above and add a few of their own. The shopfront and signage are a large, highly visible package that has no equivalent in an office, and shopping centre landlords usually have strict design guidelines that control materials, lighting levels and how far the shopfront can project. Display and service joinery is designed around the brand and the product, so it cannot be priced from a catalogue rate. Food and hospitality tenancies bring grease arrestors, kitchen exhaust, gas, cold rooms and floor waste that have to connect to base building services which may or may not exist at the tenancy.
Many factors can complicate the office fitout cost, including unforeseen structural issues that may arise once construction begins.
Assessing your office fitout cost early and often can help ensure your project stays on track and is completed within budget.
Retail programmes are also shorter and less forgiving. Centre management sets the trading start date, works are often confined to the hours the centre is closed, and every day the shop is not open is lost revenue. That combination of tight programme, night work and custom joinery is why a retail fitout cost per square metre is often higher than an office of the same size, even at a similar finish level.
Identifying the factors that affect the office fitout cost early in the process can help mitigate budget discrepancies.
Evaluating the office fitout cost will allow you to weigh your options effectively and make the best financial decisions for your business.
Why fitout budgets blow out
When a fitout finishes well over budget the cause is rarely a single bad rate. It is usually one of four things. The brief grew between the concept plan and the tender drawings, and nobody repriced it. The tenancy handover condition was assumed rather than checked, so demolition, make-good or services capacity arrived as variations. Costs outside the building contract, including design fees, landlord charges, technology, furniture, relocation and contingency, were never added to the builder’s price. Or the quotes being compared did not cover the same scope, so the cheapest tender was cheapest because it left the most out.
Each of those is avoidable with a measured estimate prepared from the actual drawings and the actual tenancy conditions. Accent Estimating’s fitout costing service covers office, retail and hospitality tenancies, measuring the works, pricing them against current rates and setting out clearly what is in the budget and what is not. The same estimate becomes the benchmark for comparing builders’ quotes on a like-for-like basis, which is where most of the real savings in a fitout are found.

Frequently asked questions
How much does an office fitout cost per square metre in Australia?
Published guides put a medium-quality office fitout in Australia at roughly AU$3,000 per square metre in 2026*, but the range around that figure is wide. A tenancy handed over with ceilings and services in place, laid out mostly open plan, will sit well below it. A cold shell with many enclosed rooms, heavy technology and a high finish level will sit well above it. The only reliable figure is one measured from your drawings and your tenancy conditions.
What is the difference between a base building and a fitout?
The base building is the landlord’s: structure, lifts, main plant, fire sprinklers and services brought to the tenancy boundary. The fitout is the tenant’s: everything needed inside the tenancy to occupy it, from partitions and ceilings to joinery, lighting, data and supplementary air conditioning. The lease and the landlord’s fitout guide define exactly where the line sits, and it differs between buildings.
Why is a retail fitout usually more expensive than an office fitout?
Retail adds a shopfront and signage package, bespoke display joinery and, for food tenancies, specialist services such as exhaust, grease arrestors and cold rooms. Works are usually restricted to hours the centre is closed and driven by a fixed trading date. Night work, short programmes and custom joinery all lift the rate per square metre.
What costs are usually left out of a fitout quote?
Design and engineering fees, landlord review and supervision charges, technology and audiovisual, furniture, relocation, authority fees, make-good at lease end and contingency. A builder’s quote normally covers the building work only. A fitout budget needs all of these added to it.
When should I get a fitout estimate?
Before the lease is signed. The handover condition of the tenancy, the landlord’s fitout rules and the incentive on offer all affect what the fitout will cost, and all of them are negotiable at lease stage and fixed afterwards. A second estimate at tender stage then gives you a benchmark to test the builders’ quotes against.
