Site Costs Upgrade Costs
Often overlooked costs before building starts
What is it?
Site Costs is one of the many inclusions that builders may include as standard, offer as a paid upgrade, or exclude entirely from their base package. Understanding where each builder stands on this item helps you compare true value rather than just headline prices.
Why buyers compare it
- Builders vary significantly in what they include as standard
- A lower advertised price may not mean better value
- Upgrades can add thousands to the real cost of your build
- Comparing inclusions is the only fair way to compare builders
Is it worth upgrading?

Compare My Build Tip
Always request a full written inclusions list from each builder, not just the highlights from a display home visit. The written specification is what legally binds the builder, not what you were told verbally.
