What is Compare My Build?

An interactive comparison platform for home buyers to evaluate builders, plans, and inclusions in their region side-by-side.

What are site costs and why are they separate from the base price?

Site costs are the costs of preparing your specific block for construction — earthworks, slab upgrades, retaining walls, stormwater, and connection of services. They are separate from the base price because they depend on the specific conditions of your block, which the builder cannot determine until a soil test and site survey are conducted.

How much should I budget for site costs?

Site costs typically range from $5,000 to $30,000+ depending on the block. A flat, clear block with good soil may cost $5,000–$10,000, while a sloping block with reactive soil can cost $20,000–$50,000 or more. Always get a soil test before signing a building contract to understand your likely site costs.

Why is the advertised 'from' price not what I'll actually pay?

Advertised 'from' prices assume a flat block, standard soil classification, basic inclusions, and no upgrades. They typically exclude site costs, flooring, driveways, landscaping, and many finishes. The actual cost of building the advertised home is usually significantly higher once these items are added.

What hidden costs should I ask about before signing?

Ask about site costs (and whether they're fixed or provisional), driveway and landscaping exclusions, flooring, blinds and curtains, fencing, letterbox, ducted air conditioning, and any items listed as 'PC' (prime cost) or 'PS' (provisional sum) in the contract.

Hidden Cost Guides

What builders don't always advertise — site costs, exclusions, and the budget blowouts that catch buyers out.

7 guides 3 categories Independent & builder-neutral

Advertised 'from' prices rarely tell the full story. Site costs, upgrade charges, and exclusions can add tens of thousands to a build. These guides explain where hidden costs come from and how to budget for them before you sign. From understanding site cost allowances and why they blow out to decoding 'from' pricing and spotting the exclusions buried in the fine print, this learning centre helps you budget for the real cost of your build — not just the advertised price.
