Your Office Fitout Budget Was Set at the Lease, Not the Quote

Two builders walked the same 260 square metre tenancy in Southport six days apart. Same drawings. Same finishes schedule. Same room count.

The quotes came back $180,000 apart.

The tenant assumed one of us was gouging. Neither was.

The cheaper builder had priced the drawings. The other had been up in the ceiling space with a torch, found that the previous tenant's grid was set out on a module that didn't align with any single new partition, and worked out that three of the four proposed meeting rooms had no return air path.

One quote described a set of walls. The other described the job.

The short answer, before the detail

A medium-quality office fitout in Australia costs around $3,011 per square metre in 2026, according to JLL's Australia and New Zealand Fit-Out Cost Guide, with costs rising between 3.5% and 6% year on year. Brisbane averages $2,979. Perth leads on $3,118, with Melbourne and Sydney a few dollars either side.

Now, the part that matters more than the average.

Three things move your number further than your builder's rate ever will:

• The condition of the space you leased
• How many enclosed rooms are you building
• What your contract quietly excludes

All three are settled before or outside the quote. Which is exactly why the quote doesn't explain them.

Asking what an office fit-out costs per square metre is like asking what a renovation costs per bedroom. The number exists. It just doesn't describe your house.

Half your budget is labour, so every decision costs double

The national average is useful for a board paper and close to useless for your project. The number that tells you something is the breakdown underneath it.

In Australia, builders' works account for roughly 50% of total fitout cost, against a global benchmark of nearer 38%. Half your money goes into partitions, ceilings, carpentry and the trades who install them, priced by a market where subcontractors can afford to be selective about which jobs they accept.

Read that as a warning rather than a statistic.

If half your cost is trade labour, every design decision that adds trade hours costs roughly double what your instinct says it should. And every building condition that makes trade access harder does the same thing, quietly, before a line has been drawn.

The most expensive line in your fitout is buried in your lease

Here is what a builder cannot change and a leasing agent rarely raises: the condition of the space you signed for.

Same 250 square metres. Same brief. Same finishes. The starting condition alone can swing the build by comfortably six figures before anyone argues about carpet.

The one-hour walk-through that saves six figures

Tenants who get this right do one thing differently. They walk the shortlisted tenancies with a fit-out contractor before the heads of agreement are signed, not after.

Across the projects Alpha Ceilings and Partitions prices around the Gold Coast and Brisbane, that hour is reliably the difference between a budget that holds and a budget that gets rewritten twice.

What the walk-through looks for is unglamorous:

• Ceiling grid module and condition
• Where mechanical services actually run, as opposed to where the drawings say they run
• Floor levels
• Whether existing light fittings can be reused or are three generations obsolete
• Whether the fire and smoke detection layout survives your room plan, or triggers a redesign of the system

One client wanted a boardroom in the north-west corner. Moving it 1.8 metres put it under an existing return air grille and saved a duct run through a structural beam.

That was $40,000, decided in ninety seconds, on a floor plan, before anything was ordered.

Every enclosed room is four trades, not one wall

The office has changed shape, and the cost has followed. JLL is direct about it: demand for enclosed meeting rooms, focus pods, and quiet spaces, driven by hybrid work and increasingly by people needing acoustic privacy to talk to AI tools, is now a bigger cost driver than open-plan areas or premium finishes.

Here is what one meeting room actually contains:

• An acoustically rated partition with the correct stud, insulation, and sealing detail
• A ceiling that doesn't leak conversation over the top of it
• A return air path and supply diffuser, so the room stays habitable with the door shut
• A lighting circuit and switching
• A data run
• Backing in the wall for a screen mount
• A door with a proper acoustic seal

Six trades touch that room. Miss the coordination on one, and it fails the only test that matters, which is whether you can hold a confidential conversation in it with the door closed. That sequencing is the quiet skill in commercial fitouts, and it's the first thing compressed when a program slips.

Technology now absorbs around 14% of the total Australian project budget, close to triple its pre-pandemic share. That isn't screens. It's cabling, containment, backing, power, and the coordination hours to land all of it before the ceiling closes.

So count your enclosed rooms before you count your square metres. On a 300 square metre floor, going from four rooms to seven will move your number further than upgrading every finish in the place.

Five costs that sit outside the builder's quote

A contractor prices their scope. Your project is larger than its scope. The gap is where budgets die.

• Make good. Most leases require you to return the premises to base building condition at expiry. A dental practice we worked with in Robina inherited a tenancy whose previous fit-out had never been documented, and at the end of the term was liable for removing walls it had never built. Photograph and document the condition on day one.
• After-hours access. Multi-tenancy buildings restrict noisy work to evenings and weekends. That carries a labour premium and stretches the program, which costs again in holdover rent.
• Compliance triggers. Your fit-out can activate upgrade obligations in an older building: fire services, accessibility, essential services. Triggered by your scope, paid from your budget.
• Landlord's consultants. Design review, building manager fees, insurance requirements, security and induction costs.
• Contingency. Ten percent minimum on a Cat A floor. More on an existing tenancy, where the strip-out will show you things nobody could have priced.

None of this is concealed. It simply sits outside the four corners of a construction contract, which is why the honest answer to "what will this cost" is always a project budget rather than a builder's number.

Why the cheapest quote is usually the dearest

Read the exclusions page first

Not the total. The exclusions.

That page is where the difference between two quotes actually lives, and where a low number is manufactured. Base building rectification excluded. Mechanical services adaptation excluded. Fire services modifications excluded. After-hours works excluded.

Each exclusion is a variation waiting to be issued at a price you will have no leverage to negotiate, because the walls are already up.

Treat provisional sums as unpriced

A provisional sum is an admission that nobody has costed the item. Three or four generous ones will make any quote look competitive on paper.

The data backs up what your gut already tells you

The Australian Bureau of Statistics tracks this pressure every quarter in its Producer Price Indexes. Non-residential building construction prices rose 4.4% nationally over the year to June 2026, and the ABS attributes the pressure directly to persistent labour shortages competing against public infrastructure and defence projects, layered on top of what it describes as heightened insolvencies stretching out project timelines and driving up uncertainty.

Queensland is running hotter than the rest of the country on both measures. Non-residential building costs here rose 8.7% annually against the 4.4% national figure, and house construction costs rose 8.0% against 5.9% nationally. Brisbane's build-up to the 2032 Games is competing for the same trades your fitout needs.

A builder pricing below cost to win work in that market is not a bargain. They are a risk with a signature on your contract.

So normalise before you compare. Same drawings, same specification, same exclusions list, same provisional sums, priced by everyone. It takes a fortnight longer, and it is the highest-return fortnight in the project.

The number nobody has quoted yet

The market is already voting on all of this. JLL reports occupiers shifting hard toward pre-fitted suites and landlord-delivered space, chasing cost certainty over bespoke design, with the traditional mid-range fit-out squeezed from both ends.

That's a rational response to an irrational process. When a build's cost is unknowable until the ceiling comes down, a slightly compromised ready-made space starts to look like risk management.

But it's a workaround, not a fix.

The tenants who keep building the workplaces they actually want will be the ones who stop treating the fitout as something that happens after the lease, and start treating the lease as the first line of the fitout budget.

Ask what it costs before you sign, not after.

Frequently Asked Questions

What is the average office fitout cost per square metre in Australia? 

Around $3,011 per square metre for a medium-quality office in 2026, on JLL's national figures, with Brisbane at $2,979 and Perth highest at $3,118. Treat it as a planning benchmark, not a quote.

Why do two builders quote the same office so differently? 

Usually, one has priced the base building's actual condition, and the other has priced the drawings. Compare the exclusion lists and provisional sums before comparing totals.

What's the single biggest thing I can do to control fit-out cost? 

Walk shortlisted tenancies with a fit-out contractor before signing the lease. Base building conditions move the budget more than any finish selection you will make later.
