What Are Hard Costs in Construction?
Updated: Oct 27
Hard costs in construction are the direct costs of physically building a structure: the materials, labour, equipment, subcontractors and site work that go into the finished building. Soft costs are the indirect costs around the build, such as design, approvals, insurance and finance. Hard costs are usually the largest part of a project budget and the easiest to estimate, because they can be measured from the plans.
Hard costs at a glance
Direct and measurable. Every hard cost ties to physical work or materials on site.
Usually the biggest line. Lenders and investors check the hard cost estimate first.
Estimated from quantities and rates. Estimators measure the plans and price each item, whereas soft costs are often fixed fees or percentages.
Check what is included. In Australia, published building rates often exclude GST, land, professional fees and external site works, so confirm what a quoted figure covers.
Why hard costs need a fresh look in 2026
Hard costs keep moving, so an estimate has a short shelf life. National construction costs rose 2.8% in the 12 months to June 2026, NSW had the strongest June-quarter rise at 1.1%, and costs are up 29.5% over five years. Suppliers are also recovering costs through fuel levies, freight and logistics surcharges rather than headline price rises (same release). An estimate prepared in 2024 or 2025 will understate what a Sydney build costs today.
Examples of hard costs in construction
Hard costs include everything a builder buys, hires or builds on site. The table groups the main categories with examples and an Australian note for each.
Hard cost category | Examples | Sydney / Australian note |
Materials | Concrete, steel, timber framing, bricks, roofing, insulation, windows, doors, tiles, paint | Supplier surcharges for fuel and freight are increasingly added on top of list prices |
Labour | Wages for carpenters, bricklayers, plumbers, electricians, tilers and labourers, plus on-costs | Sydney trade rates run above most other capitals; one 2026 report puts plumbers at about $161 per hour |
Equipment | Hired or owned cranes, excavators, scaffolding, tools and vehicles, plus fuel and operators | Crane hire and heavy plant costs rose in the June 2026 quarter (Cotality) |
Subcontractors | Fixed-price or day-rate trades such as waterproofing, roofing, stonework and landscaping | Often the biggest share of a head contractor's price |
Site preparation | Demolition, excavation, earthworks, retaining walls, drainage, temporary access | Demolishing a brick house is priced at about $175 to $280 per m² in Sydney before remediation |
Structure | Footings, slab, framing, walls, floors, roof | Soil, slope and rock drive footing and excavation cost |
Building services | Plumbing, electrical, HVAC, hot water, fire services, lifts | Higher in older homes and larger buildings |
Finishes and fixtures | Flooring, cabinetry, benchtops, tapware, lighting, cladding | The most variable line, because specification is a choice |
External works | Driveways, fencing, landscaping, services connections, estate roads | Often outside a published per-m² building rate, so price separately |
Preliminaries, margin and overheads | Site supervision, scaffolding, temporary fencing, builder's margin | Normally included inside a builder's contract price |
Car parking (apartments) | Basement excavation, structure, ramps | Priced per space; Sydney basement parking runs roughly $55,000 to $110,000 per space |
Demolition, parking and estate road rates are from the Rider Levett Bucknall (RLB) Riders Digest 2026. The plumber rate is from What's The Damage, June 2026.
What about land?
Land purchase is usually treated as its own line rather than a hard cost, even though some US guides group it with construction. In an Australian feasibility, land, stamp duty and holding costs sit alongside hard costs in the total development cost.
Hard costs vs soft costs
Hard costs pay for the physical building, while soft costs pay for everything that makes the build possible but is not part of it. The distinction matters because the two are estimated, financed and controlled differently.
Hard costs | Soft costs | |
What they are | Direct costs of building the structure | Indirect costs before, during and after construction |
Typical examples | Materials, labour, equipment, subcontractors, site work | Design, engineering, council and certifier fees, legal fees, insurance, finance charges, marketing |
How they are estimated | Quantity take-offs priced at current rates | Fixed quotes, fee scales or a percentage of build cost |
Predictability | Measurable once plans are complete | Often less visible and easier to overlook |
Who checks them | Builders, estimators, quantity surveyors | Consultants, lawyers, lenders, insurers |
Share of budget | The largest share | A smaller but significant share |
Grey areas: where do these items go?
Most cost disputes come from items that sit between the two. Treat them consistently in your budget, and write down the rule you used.
Item | Usual treatment | Why |
Builder's margin, preliminaries and overheads | Hard cost | They are inside a builder's contract price (BMT and RLB rates include them) |
Demolition and site preparation | Hard cost | Physical work on the site, though often priced separately from the building rate |
Contingency | Separate line | It covers unpriced risk within the scope and should not be buried in margin, escalation or provisional sums (Feasly) |
Escalation | Separate line | It reflects price movement between estimate date and construction midpoint |
GST | Separate line | Published quantity surveyor rates exclude it; advertised project prices often include it |
Temporary services (site power, toilets, fencing) | Soft cost in many guides, but often inside builder preliminaries in Australia | Check how your contract treats them |
Design, engineering and surveying | Soft cost | Professional fees outside the building contract |
Council, certifier fees and NSW levies | Soft cost | Statutory charges calculated from the cost of works |
Home building compensation insurance | Soft cost | Insurance premium paid before work starts |
Land and finance | Separate lines | Counted in total development cost, not construction cost |
One US guide classifies temporary site services as soft costs. Australian builders usually price site facilities in preliminaries, which is why the table flags both views.
What percentage of a construction budget are hard costs?
There is no single figure. Published guidance ranges from about 50% to over 90%, depending on what each source counts as a hard cost and whether land and finance are in the total.
Source | Hard cost share | What it measures |
Clockify (US guide) | About 70% to 80% as general guidance | Share of total project budget; the guide stresses there is no universal figure |
Clockify, citing a National Association of Home Builders example | 92.6% hard, 7.4% soft | One 2,562 sq ft single-family home |
Workyard (US guide) | Often 50% to 70% | Typical share of a construction budget |
Feasly (Australia) | Often 50% to 65% | The building contract as a share of total development cost on a residential project |
The gap between those numbers comes from the denominator. A homeowner budgeting only for the build sees hard costs as the large majority of spend. A developer whose total includes land, finance, infrastructure charges and professional fees sees the building contract fall closer to half or two-thirds. Feasly adds that demolition, external works, infrastructure charges, professional fees, contingency and finance routinely add 30% to 50% on top of the building contract in a multi-unit project.
How to use this
Write down what your total includes before you compare percentages.
For a Sydney home build, treat any rule of thumb as a sense check only, then build the budget up from quantities.
If a quote or feasibility shows a hard cost share far outside these ranges, look for a missing line item or an item counted twice.
How are hard costs estimated?
Estimators build hard costs from the bottom up: measure the quantities on the plans, price each item at current rates, then add the site-specific and market factors. A per-square-metre rate is useful for early screening, but it describes a typical building, not yours.
Measure the work. A material take-off lists every item and quantity from the drawings and specification.
Price materials. Use current supplier quotes, and check how provisional or prime cost allowances for tiles, tapware and appliances compare with what you want.
Price labour. Apply current Sydney trade rates and productivity to the hours each task needs, including on-costs.
Price equipment and subcontractors. Include hire, fuel, operators and any specialist trades.
Add site factors. Slope, rock, soil, access, demolition, services and council conditions all change the number.
Add preliminaries, margin and overheads. These are normally inside a builder's contract price.
Allow for contingency and escalation. Keep them as separate lines so they stay visible.
Check against benchmarks. Compare the result with published per-square-metre rates for your building type.
Worked example: a 240 m² Sydney project home
Using the BMT typical rate for a 3-bedroom brick veneer single-level home in Sydney, $2,424 per m² excluding GST, and replacing a 150 m² brick house:
Line | Low | High | Calculation |
Building contract | $581,760 | $581,760 | 240 m² × $2,424 |
Demolition of existing home | $26,250 | $42,000 | 150 m² × $175 to $280 |
Hard costs (ex GST) | $608,010 | $623,760 | |
GST at 10% | $60,801 | $62,376 | |
Hard costs (inc GST) | $668,811 | $686,136 | |
Contingency (separate line, ex GST) | $29,088 | $58,176 | 5% to 10% of the building contract |
This is an illustration built from published benchmark rates, not a quote. Design, engineering, approval fees, insurance, levies, landscaping and finishes above the standard specification are soft or separate costs on top.

Why hard costs matter
Hard costs set the size of your budget, your loan and your approval fees, so an error here flows into everything else.
Budget accuracy. Hard costs are the biggest line, so a small percentage error is a large dollar error.
Finance. Lenders and investors usually want a detailed hard cost breakdown before they commit funds, and a financier's own quantity surveyor may test it.
Approval fees and levies. Council, certifier and complying development fees are calculated from the estimated cost of works, and councils can challenge an estimate that is not genuine and accurate (Murray River Council fact sheet, as one example). The NSW long service levy is 0.25% of works of $250,000 or more, including GST.
Cost control. A clear hard cost baseline lets you spot overruns and variations early, instead of at final claim.
Planning and scheduling. Quantities and rates feed the program, trade sequencing and cash flow.
Escalation risk in 2026. Rider Levett Bucknall forecasts Sydney tender prices to rise about 4.0% in 2026 and expects cost risk to return late in the year (RLB), so the date of an estimate matters as much as its method.
Tips for managing hard costs in 2026
The best control comes from a measured estimate, a complete scope and a contract that makes price movement visible. Seven practical steps:
Get an independent estimate. A residential or commercial estimator or quantity surveyor can measure your plans and give you a number to test builders' quotes against.
Finish the design before you tender. Incomplete documents are the main source of variations, and incomplete designs justify higher contingencies.
Hold contingency on its own line. Feasly's guidance suggests 5% to 10% once scope is firm and 10% to 20% at early concept stage, with more for refurbishments and complex sites.
Check allowances and surcharge clauses. Ask how provisional sums, prime cost items and fuel or freight surcharges are handled, and how long the price is held.
Compare itemised quotes. Look at inclusions and exclusions line by line, not only the total. Our guide to checking whether a builder's quote is fair shows how.
Track costs against the baseline. Review progress claims and variations monthly, and update the forecast when scope changes.
Re-price when the market moves. With Sydney tender prices forecast to rise about 4% in 2026, refresh any estimate that is more than a few months old.
Frequently asked questions
What are hard costs in construction?
Hard costs are the direct costs of physically constructing a building, including materials, labour, equipment, subcontractors, site preparation and the builder's preliminaries and margin.
What is the difference between hard costs and soft costs?
Hard costs build the structure. Soft costs support it and include design, engineering, council fees, legal fees, insurance and finance charges.
Is labour a hard cost?
Yes. Wages for trades and labourers, and related on-costs such as payroll taxes and leave, are hard costs because they pay for work done on the building.
Is land a hard cost?
Usually no. Land is normally a separate line in the budget, although some guides group it with construction costs.
Is demolition a hard cost?
Yes. Demolition and site preparation are physical work on the site, but they are often priced separately from a building's per-square-metre rate.
Are architect and engineering fees hard or soft costs?
Soft costs. They are professional fees for design and documentation rather than physical construction.
Are permits and council fees hard costs?
No. Development application, construction certificate and complying development fees, and levies such as the NSW long service levy, are soft costs.
Is contingency a hard cost?
It is usually shown as its own line, calculated as a percentage of the hard costs, so it stays visible and is not mixed with margin or escalation.
Do hard cost figures include GST?
It depends on the source. Published quantity surveyor rates for Sydney are usually quoted excluding GST, while advertised project home prices often include it. Always check.
How much do hard costs run per square metre in Sydney in 2026?
BMT rates for a standard single-level project home in Sydney run roughly $2,200 to $3,150 per m² excluding GST, with custom designs from about $3,050 and architect-designed homes from about $4,500.
Who calculates hard costs?
Estimators and quantity surveyors measure the plans and price each item. An independent estimate is a useful check on a builder's quote.
Conclusion
Hard costs are the measurable, physical cost of building, and they usually drive most of your budget. Separate them clearly from soft costs, decide where the grey-area items sit, and keep contingency and escalation on their own lines. Because Sydney costs are still rising and suppliers are adding surcharges, base your numbers on a current, measured estimate rather than an old benchmark.
