Construction Cost per Square Metre in Australia (2026)

Construction costs in Australia in 2026 may typically range from around $2,000 to $4,300 per square metre for houses, $3,500 to $7,000 per square metre for apartments depending on the city and building height, and roughly $850 to $2,400 per square metre for industrial sheds, all measured against Gross Floor Area (GFA) and quoted exclusive of Goods and Services Tax (GST). Those are wide ranges, and that is the point. A square metre rate is a benchmarking tool, not a price. Used well, it gets a feasibility usefully close to reality before you spend a dollar on consultants. Used badly, it quietly sinks a project margin.

Most of what ranks for this search term is written for someone building their own home. This guide is written for a developer applying rates across a whole project: which rates to use for each asset class, what the published figures include and leave out, how the rates differ between cities, what escalation allowance to carry, and how to put the number into a feasibility model without fooling yourself. The benchmark figures come from the two sources Australian quantity surveyors actually use, the Rawlinsons Australian Construction Handbook and the Rider Levett Bucknall (RLB) Riders Digest 2026, alongside the BMT construction cost table and current index data.

What is a construction cost per square metre?

A construction cost per square metre is the total building contract cost divided by the building’s Gross Floor Area (GFA). It covers what a builder would normally price in a lump sum building contract: the substructure, structure, finishes, fittings, building services, preliminaries, and the builder’s margin and overheads. It is the fastest way to estimate a build cost when all you know is the building type, the approximate area, and the city.

The important word is estimate. Quantity Surveyor (QS) publications describe their square metre rates as the range you could expect if tenders were called today for a typical building of that type. Your building is not typical. Site conditions, design efficiency, specification level, procurement route, and the state of the local tender market can each move the outcome well outside the published band. Rider Levett Bucknall (RLB) publishes its cost data as ranges rather than single figures for exactly this reason, and pairs every table with a note that costs vary with site and market conditions. Treat any single-figure rate you are given with suspicion, and treat the range as a starting envelope to be tightened by a Quantity Surveyor (QS) as design develops.

What does a published square metre rate include and exclude?

A published rate generally includes everything inside the building contract and excludes almost everything else in your development budget. The Rider Levett Bucknall (RLB) Riders Digest 2026 lists its specific exclusions, and they are worth reading twice because every one of them is a real cost you still have to fund:

• Goods and Services Tax (GST)
• Land
• Legal and professional fees (including design consultants and the Quantity Surveyor (QS) themselves)
• Site works and drainage outside the building
• Loose furniture and fittings
• Tenancy and fitout works
• Car parking, which Rider Levett Bucknall (RLB) strips out of its building rates and prices separately

The BMT construction cost table works the same way: its rates allow for preliminaries, builder’s profit and overheads, and are quoted exclusive of Goods and Services Tax (GST).

Two traps follow from this. First, project home advertising works in the opposite direction: a volume builder’s “$350,000 turnkey” price is usually inclusive of Goods and Services Tax (GST), so comparing an advertised house price against a Quantity Surveyor (QS) rate table is an apples-to-oranges comparison that can flatter a feasibility by 10 per cent before you start. Second, the exclusions are not small. Demolition, external works, infrastructure charges, professional fees, contingency and finance costs routinely add 30 to 50 per cent on top of the building contract in a multi-unit project. A square metre rate estimates the contract, not the project. The full stack is covered in our guide to Total Development Cost (TDC).

Which area do you multiply the rate by?

Square metre rates apply to Gross Floor Area (GFA), not to saleable area, and mixing the two is one of the most common errors in quick feasibilities. Gross Floor Area (GFA) in cost estimating is generally measured as the sum of two elements:

• Fully Enclosed Covered Area (FECA): everything within the external walls at every level, including basements, garages, lift shafts, stairs, and plant areas.
• Unenclosed Covered Area (UCA): roofed but unenclosed space such as covered balconies, verandahs, porches and covered walkways.

The BMT construction cost table applies its rates to exactly this definition. The practical consequence for an apartment developer: the areas you sell (internal apartment area) may be only 70 to 85 per cent of the areas you build (which include corridors, lobbies, services risers and structure). Applying a Gross Floor Area (GFA) rate to your saleable area understates the build cost by that efficiency gap, which on a mid-rise project can be the entire development margin.

Rider Levett Bucknall (RLB) publishes efficiency percentages against its office rates for the same reason. A prestige Central Business District (CBD) office tower of 10 to 25 storeys might run at 75 to 80 per cent efficiency, and Rider Levett Bucknall (RLB) notes the Net Lettable Area (NLA) rate is calculated by dividing the Gross Floor Area (GFA) rate by that efficiency percentage. A $5,500 per square metre Gross Floor Area (GFA) rate at 75 per cent efficiency is roughly $7,300 per square metre of Net Lettable Area (NLA). Same building, very different number. The full set of area definitions, and how they flow through to revenue, is in our guide to Gross Floor Area (GFA), Net Lettable Area (NLA) and saleable area.

How much does it cost to build a house in 2026?

A standard single-level project home may typically cost $2,000 to $2,900 per square metre in Sydney in 2026, with custom and architectural homes running from around $3,000 to more than $8,000 per square metre. The BMT construction cost table, current for 2026 and quoted per square metre of Gross Floor Area (GFA) exclusive of Goods and Services Tax (GST) on a Sydney basis, gives:

The Rider Levett Bucknall (RLB) Riders Digest 2026 quotes custom built single and double storey dwellings in Sydney at $2,500 to $7,600 per square metre, a deliberately wide band that reflects how much specification drives the number at the top end.

To turn a rate into a build cost, multiply by a realistic area. Australian Bureau of Statistics (ABS) data puts the average new house at roughly 230 to 245 square metres of floor area, a figure that has barely moved in 15 years. At the BMT medium rate for a brick veneer project home, a 240 square metre house may cost somewhere around $580,000 exclusive of Goods and Services Tax (GST) before site costs, external works and professional fees. If a consumer cost guide tells you houses are built for $1,600 per square metre, it is usually describing a volume builder’s base specification on a flat lot with siteworks and finishes stripped out, which is not a number a developer should carry into a feasibility for anything other than exactly that product.

How much do townhouses cost per square metre?

Townhouses may typically cost $3,200 to $4,300 per square metre in Sydney at 2026 rates, noticeably more than a comparable project home. The BMT construction cost table prices a 3 bedroom two-level brick veneer townhouse, including an allowance for common property, at $3,256 (low), $3,793 (medium) and $4,318 (high) per square metre of Gross Floor Area (GFA).

The premium over a detached house catches developers who price a townhouse scheme off a project home rate. It exists for structural and practical reasons: party walls and fire separation, common property works (driveways, visitor parking, shared landscaping and services), tighter sites with harder access, and preliminaries spread over a slower, more constrained build. The Rider Levett Bucknall (RLB) Riders Digest 2026 publishes city ranges for townhouses of 90 to 120 square metres per unit that run from roughly $2,250 per square metre at the bottom of the Adelaide range to $5,300 at the top of the Canberra and Perth ranges. For Sydney, Rider Levett Bucknall (RLB) quotes townhouses per unit rather than per square metre: $425,000 to $775,000 per townhouse at Fourth Quarter 2025 rates, excluding car parking and site works. Cross-checking a per square metre estimate against a per unit figure like this is a habit worth building; when the two disagree materially, your area assumptions are usually the problem.

How much do apartments cost per square metre in 2026?

Apartment construction may typically cost $3,500 to $5,800 per square metre of Gross Floor Area (GFA) for buildings up to 10 storeys in the major capitals, rising to $4,500 to $7,000 or more once a tower passes 20 storeys. The Rider Levett Bucknall (RLB) Riders Digest 2026 publishes these ranges at Fourth Quarter 2025 rates, per square metre of Gross Floor Area (GFA), exclusive of Goods and Services Tax (GST) and excluding car parking, for units of 60 to 70 square metres:

Three patterns in that table matter for feasibility work. First, rates climb with height: structure, vertical transport, services and preliminaries all get more expensive per square metre as a building gets taller, so a taller scheme needs a higher revenue per square metre to hold its margin, not just more square metres. Second, larger apartments cost slightly less per square metre than smaller ones (kitchens and bathrooms are the expensive rooms, and bigger units dilute them across more area), so a build-to-sell scheme of compact units carries a structurally higher rate than the same Gross Floor Area (GFA) in bigger apartments. Third, Brisbane’s ranges now sit at or above Sydney’s in the taller bands, which would have looked like a typo five years ago.

Walk-up product without lifts or basements prices well below all of this. Rider Levett Bucknall (RLB) quotes walk-up units of 85 to 120 square metres from roughly $2,250 to $5,800 per square metre depending on the city, and BMT prices a three-level walk-up complex in Sydney at $3,370 to $4,389 per square metre.

Basement car parking is the other large number the headline rate hides. Rider Levett Bucknall (RLB) prices Sydney basement parking at $58,000 to $110,000 per space in the Central Business District (CBD) and $55,000 to $100,000 per space outside it, based on 30 square metres per car. On a 100-unit project with 1.2 spaces per unit, parking alone can be a $7 million to $12 million line that never appears in a per square metre comparison of building options. Price it separately, always.

What do commercial, industrial and retail buildings cost per square metre?

Industrial is the cheapest space you can build at around $850 to $2,000 per square metre, offices the most expensive at $3,200 to $7,800 depending on grade, and retail sits in between. Indicative 2026 ranges from the Rider Levett Bucknall (RLB) Riders Digest at Fourth Quarter 2025 rates:

Hotels are usually benchmarked per key rather than per square metre because room count drives revenue. Rider Levett Bucknall (RLB) quotes Sydney multi-storey hotels at $322,500 to $432,500 per room for three star and $677,500 to $855,000 per room for five star, excluding Furniture, Fittings and Equipment (FF&E), which adds a further $36,750 to $157,500 per room depending on the rating. If you are modelling a hotel or serviced apartment scheme off a residential square metre rate, you are underdone before you begin.

The commercial rates come with the same exclusions as residential: fitout in particular. An office rate described as “excluding fitout” is a warm shell. Integrated fitout for a tenant can add $1,860 to $5,800 per square metre in Sydney depending on the tenancy type, which matters if your leasing strategy assumes a turnkey offer.

How do construction costs vary between cities and regions?

Brisbane is now the most expensive city in Australia and New Zealand to build in, according to Turner & Townsend’s Global Construction Market Intelligence 2025 report, which puts Brisbane’s average construction cost at US$3,135 per square metre, ranked 36th globally and seven places ahead of Sydney. A decade of Sydney leading the cost tables has ended, driven by south-east Queensland’s infrastructure and Olympics pipeline competing for the same trades as its residential sector.

For quick city adjustments, the BMT construction cost table publishes regional multipliers against its Sydney base rates: Melbourne at 94 to 105 per cent, Brisbane at 92 to 105 per cent, Adelaide at 90 to 108 per cent, Canberra at 92 to 110 per cent, Hobart at 90 to 100 per cent, Cairns at 90 to 110 per cent, Perth at 98 to 120 per cent, and Darwin at 110 to 120 per cent. Perth and Darwin above Sydney parity is the detail most eastern-seaboard developers miss: labour scarcity and freight distances mean the cheapest land in the country does not come with the cheapest buildings.

Two cautions on applying these. The multipliers are ranges, not points, and where your project lands in the range depends on how hot the local tender market is when you go out to price. And truly regional sites (as opposed to regional cities) can price above metro on the same drawings once travel, accommodation and thin subcontractor competition are loaded in, so a regional discount assumption should be tested rather than assumed.

How fast are construction costs rising, and what escalation should you allow?

National residential construction costs rose 2.5 per cent over the year to December 2025, the smallest annual rise since March 2002, but the quarterly trend is turning back up and forecasters expect 4 to 5.5 per cent annual escalation in most capitals through 2026 and 2027. Three current data points frame the escalation question:

• Cotality’s Cordell Construction Cost Index (CCCI) recorded a 1.0 per cent national increase in the December 2025 quarter, the strongest quarterly growth of the year, taking annual growth to 2.5 per cent, still well below the pre-pandemic decade average of 4.7 per cent.
• The Rider Levett Bucknall (RLB) Tender Price Index (TPI) forecasts for calendar 2026 sit at 4.0 per cent for Sydney and Melbourne, 5.0 per cent for Brisbane, 5.1 per cent for Adelaide, 5.3 per cent for Perth, 5.5 per cent for the Gold Coast and 6.0 per cent for Townsville, with Queensland markets forecast to run at 7.0 per cent through 2027 to 2029.
• Australian Bureau of Statistics (ABS) Building Activity data shows total dwelling commencements jumped 8.0 per cent to 53,567 in the December 2025 quarter, with private sector apartment and townhouse commencements up 23.4 per cent, and 236,858 dwellings under construction nationally. More work chasing the same trades tends to push tender prices up, which is why the tender price forecasts sit above the current cost index.

Note the distinction between those two kinds of index. A construction cost index like the Cordell Construction Cost Index (CCCI) tracks input costs (materials and labour). A Tender Price Index (TPI) tracks what builders actually bid, which adds market conditions and margin appetite on top. In a heating market, tender prices rise faster than input costs; that gap is what caught developers who priced projects in 2020 and tendered them in 2022.

For feasibility purposes the standard discipline is to escalate your rate from the date of the benchmark to the midpoint of your construction period, not to the start date. A benchmark struck at Fourth Quarter 2025, applied to a project starting in mid 2027 with an 18 month build, needs roughly two and a quarter years of escalation carried on top, which at current capital city forecasts could mean 9 to 12 per cent before a shovel moves. The timing of when those costs actually fall due, and what that does to your funding line, is the territory of development cashflow modelling. Staged changes to the National Construction Code (NCC) can also nudge rates between editions as states adopt new requirements, so it may be worth checking what code applies at the time your building approval is lodged rather than assuming today’s basis.

What does a square metre rate leave out of your feasibility?

The rate estimates the building contract only, so a feasibility built on rate times area alone is missing most of its cost lines. On top of the construction estimate, a typical project still needs to fund:

• Demolition and site preparation. Rider Levett Bucknall (RLB) prices demolition of a brick house at $175 to $280 per square metre and a multi-storey building at up to $580 per square metre in Sydney, before any remediation.
• External works and services. Driveways, landscaping, drainage, utility connections and road works sit outside the building rate. On subdivisions and townhouse schemes these can rival the building cost itself; Rider Levett Bucknall (RLB) prices residential estate roads at $1,820 to $3,100 per lineal metre.
• Car parking, priced per space as covered above.
• Professional fees. Architects, engineers, planners, certifiers, project managers and the Quantity Surveyor (QS).
• Authority and infrastructure charges. Council contributions, service authority headworks and, in some states, affordable housing contributions.
• Contingency. A design and construction contingency sized to the maturity of your documentation, covered in our guide to construction contingency.
• Escalation to the construction midpoint, as above.
• Goods and Services Tax (GST), finance costs, and land, each modelled on its own line.

The clean way to think about it: the square metre rate feeds one line of the Total Development Cost (TDC) stack. It is usually the biggest line, often 50 to 65 per cent of the total on a residential project, but a feasibility that treats it as the whole cost side will usually look better than the project that eventually gets built.

How do you apply a square metre rate in a feasibility model?

Apply the rate to a properly measured Gross Floor Area (GFA), adjust it for what makes your project non-typical, escalate it, then build the excluded costs around it as separate lines. As a working sequence:

1. Measure Gross Floor Area (GFA) off the drawings, including basement, parking structure, common areas and covered outdoor area, using the Fully Enclosed Covered Area (FECA) plus Unenclosed Covered Area (UCA) convention. If all you have is a yield study in saleable area, gross it up by a realistic efficiency ratio before applying any rate.
2. Pick the right benchmark for the product, not a nearby one. A rate for units up to 10 storeys does not price a 15 storey scheme; a project home rate does not price a townhouse.
3. Position within the range deliberately. Difficult ground, small floor plates, high external wall ratios, premium specification and constrained sites all push you toward the top of the band. Be honest about which of those apply.
4. Escalate to the construction midpoint using a current Tender Price Index (TPI) forecast for your city.
5. Add the excluded lines separately: parking per space, external works, demolition, professional fees, authority charges, contingency.
6. Stress-test the rate before you commit. Construction cost is usually the largest and least controllable input in the model, so flex it 5, 10 and 15 per cent and watch what happens to margin and residual land value. Sensitivity analysis in a tool like Feasly is built for this, and a cost-assist feature that inserts the typical line items for your development type and state keeps the lines the rate excludes staring at you rather than forgotten.

A structure for the whole model, with the construction lines in context, is in our development feasibility spreadsheet guide.

When should you move beyond square metre rates?

As soon as a real decision hangs on the number. Square metre rates are appropriate for site screening, offer formulation and early scheme comparison. Once you are optioning land at a price that only works at $3,800 per square metre, you want an elemental cost plan from a Quantity Surveyor (QS), typically commissioned at concept design and refined at each design stage. An elemental plan measures actual quantities against the drawings (so a jump in facade area or basement depth shows up as cost rather than hiding inside an averaged rate) and it gives you a defensible basis for the cost line your financier’s Quantity Surveyor (QS) will later interrogate.

The published references remain useful throughout: the Rawlinsons 2026 cost guide and handbook for detailed rates and regional indices, and the Rider Levett Bucknall (RLB) online construction cost calculator for quarterly-updated city benchmarks. From tender onwards, the market replaces the book: the numbers that matter are the ones builders return, and the procurement decisions that shape them are covered in our guide to choosing a builder.

What are construction costs per square metre in New Zealand?

New Zealand construction costs may typically run NZ$4,700 to NZ$6,600 per square metre for multi-storey apartments and NZ$1,200 to NZ$1,900 for industrial warehouses, with cost growth currently subdued. The Rider Levett Bucknall (RLB) Riders Digest 2026 international tables, at Fourth Quarter 2025 rates in New Zealand dollars per square metre of Gross Floor Area (GFA), show Auckland multi-storey residential at NZ$5,500 to NZ$6,500, Wellington at NZ$5,800 to NZ$6,600 and Christchurch at NZ$4,700 to NZ$5,600, with premium Auckland offices at NZ$5,500 to NZ$6,700 and industrial warehouses at NZ$1,200 to NZ$1,500.

The escalation picture is softer than Australia’s. Cotality’s New Zealand Cordell Construction Cost Index (CCCI) rose 0.9 per cent in the December 2025 quarter for annual growth of 2.3 per cent, well under its long-run average of 4.1 per cent, and QV CostBuilder, the standard New Zealand cost database with rates across six regions updated quarterly, has reported annual residential cost growth as low as 1.2 per cent through the recent downturn. Rider Levett Bucknall (RLB) forecasts 2026 tender price growth at 3.0 per cent for Auckland and Wellington and 2.5 per cent for Christchurch, below every Australian capital. With dwelling consents recovering, both Cotality and Rider Levett Bucknall (RLB) flag that the flat period may not last, so the same midpoint escalation discipline applies on either side of the Tasman.

The short version

Square metre rates are the right tool for early-stage cost estimating, provided you respect what they are. Match the rate to the product and the city, apply it to Gross Floor Area (GFA) measured on the Fully Enclosed Covered Area (FECA) plus Unenclosed Covered Area (UCA) convention, position within the published range deliberately, escalate to the construction midpoint, and model everything the rate excludes as its own line. Then stress-test it, because at 50 to 65 per cent of Total Development Cost (TDC), few assumptions in your feasibility move the answer as far as this one. And once real money hangs on the number, pay a Quantity Surveyor (QS) to replace the benchmark with a measured cost plan. The rates in this guide are current at the time of writing; check the source publications for the latest figures before relying on any of them, because this market has a habit of moving while documents sit in a drawer.
