Site Costs

Site costs are one of the most variable and least understood components of a building contract. Two builders quoting the same house design on the same block can differ by tens of thousands of dollars purely based on how they handle site works — and many buyers don't discover the real figure until well after signing.

What is it?

Site costs cover all the groundworks required before your home's slab can be poured — earthworks, slab classification and engineering, soil removal, rock excavation, retaining structures, and connection of services. Builders typically quote these as either a fixed allowance or a provisional sum that can change once soil tests are completed.

Why buyers compare it

Site costs can vary by $10,000–$50,000+ between builders on the same block
Provisional sum allowances are a common source of post-contract cost blowouts
Some builders quote unrealistically low site cost allowances to win the tender
Fixed site cost contracts eliminate the biggest single budget risk in a build

Is it worth upgrading?

Your block has a slope, fill, or known reactive soil conditions

You want budget certainty and no surprise variations during construction

You're comparing builders and need a true like-for-like total price

Your block is flat, sandy, and straightforward with known M-class soil

Your builder has completed a proper soil test and provided a fixed site cost

Questions to Ask Your Builder

Are site costs fixed or quoted as a provisional sum?What soil class has been assumed (M, H1, H2, E)?Does the allowance include rock excavation if encountered?Is site scrape, fill import, and spoil removal included?Are service connections (water, sewer, power, gas) included?What happens if actual site costs exceed the allowance?

Site Costs — Typical Costs

Flat Block — M-Class

$5,000 – $15,000

Standard slab, minimal earthworks, straightforward connections

Sloping or Fill Block

$15,000 – $35,000

Cut and fill, engineered slab, possible retaining walls

Reactive or Rocky Soil

$30,000 – $60,000+

H-class or piered slab, rock excavation, deep footings

Compare My Build Tip

Always ask for a fixed site cost quote backed by an actual soil test — not an allowance. A builder quoting $12,000 for site costs without a geotechnical report is guessing, and any shortfall becomes your variation during construction.
