Can a builder pass me a price increase once I’m already on site?

The short answer? It depends on the contract you’ve signed.

➡ Is it governed by the Home Building Contracts Act (under $500k)?
➡ Over $500k? Standard HIA/MBA template?
➡ Or is it a custom contract with rise and fall clauses?

The bigger issue here is signing a contract you don’t truly understand, or worse, only finding out about the conditions after you’ve spent thousands of dollars and months going through the preliminary stages.

You also need to keep in mind, it’s not always in a consultant’s interest to walk you through the finer details upfront. If you’ve never built before, you simply don’t know what you don’t know - so you don’t know what questions to ask.

This is where most people get caught.

They assume:

“Fixed price means fixed”
“The builder will absorb delays”
“Once construction starts, I’m safe”

But that’s not always how it works.

If you want real control over your build, you need to understand the risks before you sign - not when it’s too late.

If you’re unsure about your contract or want peace of mind before your build starts, contact us for a free consultation. We’ll help you understand exactly what you’re entitled to and how to protect your budget.

Lest We Forget.

Today, we pause to honour the courage, sacrifice and resilience of all those who have served our country.

ANZAC Day is a reminder of the values they fought for - bravery, commitment and putting others before themselves. It’s also a time to reflect on the freedoms and opportunities we have today, including the chance to build a life and a home of our own.

To all the veterans, service members and their families, we thank you, we remember you and we will never forget.
