Pricing with Clarity & Confidence

How much does it cost to build with us?

It’s the question we get asked the most — and the one everyone wants a straight answer to. The truth is, no two custom homes are the same, so pricing shouldn’t be guessed.

We don’t guess. We price with precision.

Why We Don’t Use “Cost Per Square Metre”

Rather than throwing out misleading averages, we follow a proven pricing process designed to protect your investment and eliminate risk from day one.

This is the difference between informed decisions now — and budget blowouts later.

Our Proven Pricing Process

STEP 1

Qualifying Budget Estimate (QBE)

A comprehensive, full-day project feasibility study completed by our estimating team.

Key points as icon list or bullets:

  • Labour — the biggest risk in any custom build

  • Materials — benchmarked to current market rates

  • Subcontractors — based on real data from recent projects

We break your project into up to 30 labour categories, calculating hours and costs for every task. This produces a realistic budget range with a target accuracy of ±10%, depending on documentation.

Know exactly where your money is going — before committing to full design and documentation.

STEP 2

Final Build Estimate (FBE)


A fully costed, ready-to-build proposal based on completed construction documentation.


Once your project is approved at the QBE stage, our team invests significant time developing a detailed proposal outlining every allowance in your build.

  • Fixed upfront fee (based on projected project value)

  • 4–6 week pricing period

  • Fully transparent allowances


A confident, accurate estimate you can build from — no surprises.
