A construction loan doesn't hand over the money. It releases it, as your home rises.
Building is different to buying, and so is the loan. Instead of one lump sum, funds are released in stages as each milestone is finished — and you pay interest only on what's been drawn, not the whole loan. It's a structure designed to protect you: the lender pays for work once it's actually done. Here's exactly how the money flows, stage by stage.
Six stages, released as the build hits each milestone.
Your builder invoices at each completed stage; the lender inspects, then releases that slice of the loan. The bar shows how much of your loan is drawn as the build progresses — you're only ever charged interest on what's actually been paid out.
Stage percentages are typical only and illustrative — the actual split is set by your builder's fixed-price contract and varies by lender and state. Before the final payment, the lender orders an "as if complete" valuation to confirm the build matches the approved plans. Not an offer of credit.
Three features you won't find on a normal home loan.
Interest-only while you build
During construction you pay interest only, and only on the funds drawn so far — so early on, when little is drawn, repayments are low. At completion it converts to standard principal & interest.
Fixed-price building contract
Lenders require a signed fixed-price contract from a licensed builder. It caps the cost, defines each stage, and protects you and the lender from blowouts before a dollar is released.
Valued "as if complete"
The lender values the property on what it'll be worth once built, per your plans and contract — so your borrowing is assessed against the finished home, not the empty block.
Building is picking up, and cost pressure is easing.
After a few brutal years for construction costs, the picture is calmer — which makes a fixed-price build easier to plan around.

Staged payments aren't red tape. They're your safeguard.
Construction is the hardest sector in the economy right now — it accounted for around 27% of all company insolvencies in Australia (about 2,975 businesses) in a single recent year. When a builder fails mid-project, it's devastating. The way a construction loan is built is your defence against it.
Because funds are released only after each stage is finished and inspected, you never pay ahead for work that hasn't happened — and a fixed-price contract with a licensed builder caps your exposure. We help you structure it so the protections actually work in your favour.

Four common paths — each financed a little differently.
Land & construction
Buy the block and fund the build in one facility — the land settles first, then the build draws down progressively. Or fund a build on land you already own.
Knock-down rebuild
Demolish an existing home and rebuild on the same block, using the land's equity. Financed much like a standard construction loan, with demolition as an early stage.
Owner-builder
Building it yourself is possible but tougher to fund — only a few lenders, and typically a lower LVR (often ~50–60% vs 80–95% with a registered builder), because there's no builder's licence or statutory warranty behind it.
New-build grants
Building new can unlock first-home-buyer grants and concessions — but these are state-based and change often (Queensland, for example, offers a $30,000 grant for eligible new homes under a value cap). We'll point you to what applies where you're building.
Construction loans, answered straight.
How do construction loans work in Australia?
Funds are released in stages (progress payments) as the build hits milestones — deposit, base, frame, lockup, fixing and completion. You pay interest only on the amount drawn at each stage, and at practical completion the loan converts to a standard principal & interest home loan.
What deposit do I need?
Commonly around 20% of the total land-plus-build cost (sometimes 5–10% with lenders' mortgage insurance), assessed against the "on completion" value. Owner-builders generally need a much larger deposit. We'll give you a realistic figure for your plan.
Can I get a construction loan as an owner-builder?
It's possible but harder — only a handful of lenders offer it, usually at a much lower LVR (often around 50–60%), because there's no registered builder's licence or statutory warranties behind the build. Using a registered builder makes finance considerably easier and cheaper.
How long does the construction period last?
The drawdown/build period is typically up to 12 months (some lenders allow 24). You can buy the land first with a land loan and fund the build later, or combine both in a single land-and-construction facility.
Do I need a fixed-price building contract?
Almost always, yes — lenders require a signed fixed-price contract from a licensed builder before approving construction finance. It caps the cost, sets the stages, and is a core protection for you as much as for the lender.
Does it convert to a normal home loan?
Yes. At practical completion the loan automatically switches from interest-only to standard principal & interest repayments — you don't need to refinance to make that happen.
