A construction loan releases funds progressively as your home is built, rather than providing the full loan amount upfront like a standard home loan.
Most buyers in Werribee are familiar with the process of buying an established home - you borrow the full amount, settle, and own the property outright. When you're building from scratch, whether on land you already own or as part of a land and build loan, the lender won't hand over the entire loan amount on day one. Instead, funds are released at key milestones throughout the build. You only pay interest on the amount drawn down at each stage, not the full loan amount. Once construction is complete, the loan typically converts to a standard home loan with principal and interest repayments.
How progressive drawdown actually works
The lender releases funds in instalments tied to specific stages of construction, and each release requires a progress inspection to confirm the work has been completed. Most lenders use a five or six-stage drawdown structure: slab, frame, lockup, fixing, and completion are common checkpoints. Some lenders charge a Progressive Drawing Fee each time an inspection is arranged and funds are released, usually between $300 and $500 per drawdown.
Consider a scenario where you're building a project home in Werribee on land you already own. Your fixed price building contract is for the construction component, and your lender has approved the loan amount based on the final valuation once the home is complete. At slab stage, the builder requests the first payment - typically around 15% of the contract value. You submit the builder's invoice and progress claim to your lender, who arranges an inspection. Once the inspector confirms the slab is complete and compliant with council plans, the lender releases that portion of the loan. Interest starts accruing only on that drawn amount. The same process repeats at frame stage, lockup, and so on until the final drawdown at completion.
Interest charges during the build
You're charged interest only on the funds that have been released so far, which means your repayments start low and increase as more of the loan is drawn. During construction, most lenders offer interest-only repayment options, so you're not paying down the principal while the build is still underway. This keeps costs lower in the short term, particularly if you're also paying rent or a mortgage on your current home.
In the earlier example, if $75,000 has been drawn by lockup stage and the construction loan interest rate is 6.5%, you'd be paying interest on $75,000, not the full loan amount. Once the build is finished and all funds have been released, the loan converts to a standard variable or fixed rate home loan, and you begin making principal and interest repayments unless you've arranged otherwise.

Fixed price contracts and cost plus arrangements
Most lenders prefer a fixed price building contract because it gives them certainty about the final loan amount and reduces the risk of cost blowouts. Under a fixed price contract, the builder agrees to complete the home for a set amount, and any variations or upgrades are documented separately. This structure works well for project home builders and is the most common approach for land and construction packages in growth areas like Werribee.
A cost plus contract, where the builder charges for actual costs plus a margin, introduces more uncertainty. Lenders are cautious with these arrangements because the final cost can shift, affecting the loan-to-value ratio and your ability to service the debt. If you're working with a custom design or engaging an owner builder, expect lenders to ask for detailed cost breakdowns, quotes from plumbers and electricians, and evidence that contingency funds are in place.
What happens if the build goes over budget
If construction costs exceed the original loan approval, you'll need to cover the shortfall yourself or apply for a loan top-up. Lenders assess the increased amount against the updated valuation and your financial position at the time. In some cases, this means providing additional deposit funds or accepting a higher interest rate if the loan-to-value ratio has changed. Variations to the building contract, unexpected site costs, and delays that push the project past the expected timeline can all contribute to budget pressure.
Werribee has seen steady demand for house & land packages and knock-down rebuilds, particularly in estates around Wyndham Vale and the growth corridor toward Tarneit. Blocks in newer subdivisions often come with standard site conditions, which reduces the risk of unexpected earthworks or soil treatment costs. If you're building on a block in an older pocket of Werribee closer to the town centre or near Watton Street, be prepared for the possibility of additional site prep costs, particularly if services need upgrading or the block has unusual contours.
Timing requirements and settlement conditions
Most construction loan approvals require you to commence building within a set period from the Disclosure Date, typically six months. If you don't start within that window, the lender may reassess the loan or withdraw the approval altogether. This is particularly relevant if you're buying land and intend to build later - holding land without construction activity can affect your borrowing capacity and the loan structure available to you.
Once the development application and council approval are finalised, the progress payment schedule kicks in. Registered builders in Victoria work to a timeline agreed in the contract, and delays on either side can create complications. If the builder falls behind, you may still be paying interest on funds already drawn while waiting for the next stage. If you're delayed in securing finance for a progress payment, the builder may pause work or enforce penalty clauses in the contract.
What lenders look for in a construction loan application
Lenders want to see that the project is viable, that the builder is credible, and that you can service the loan once construction is complete. That means a registered builder with appropriate insurance, a detailed contract, council approval in place or imminent, and a clear progress payment finance structure. If you're planning a renovation or a knock-down rebuild rather than a greenfield build, lenders will also assess the current value of the land and any existing dwelling.
Access to construction loan options from banks and lenders across Australia varies depending on whether you're building with a volume builder on a standard block or pursuing a custom home with a boutique builder. Mainstream lenders are comfortable with project homes and land and construction packages in established estates. Specialist lenders come into play when you're doing something less conventional, such as spec home finance, owner builder projects, or significant renovations that alter the dwelling's footprint or structure.
Construction loans for renovations and improvements
If you own your home in Werribee and want to renovate or extend, a house renovation loan works on similar principles to new home construction finance. Funds are released progressively based on the scope of work, and you'll need quotes, council plans if structural changes are involved, and a clear breakdown of costs. Lenders distinguish between cosmetic upgrades and structural work - if you're adding a second storey or changing the roofline, expect more scrutiny and a formal valuation before approval.
Renovation finance is often structured as a home improvement loan with an interest-only period during the works, converting to principal and interest once complete. The key difference from a new build is that you're already living in the property or holding it as an investment, so serviceability is assessed with your existing mortgage and the additional loan combined.
Choosing the right loan structure for your build
Some buyers start with land finance and then apply for construction funding once they're ready to build. Others take out a combined land and construction package from the outset, which locks in the total loan amount and avoids the need to reapply later. The second option usually makes sense if you're buying in a new estate and plan to build within six months. The first option suits buyers who want to secure suitable land now but aren't ready to commit to a build timeline yet.
If you're considering an off the plan finance arrangement where the developer handles construction, the loan structure is different again - settlement occurs once the dwelling is complete, and you're not managing the progress payment schedule yourself. That's a separate process, closer to buying an established home, though it still involves construction risk and timing uncertainty.

Frequently Asked Questions
How does a construction loan differ from a standard home loan?
A construction loan releases funds progressively as the build reaches key milestones, and you only pay interest on the amount drawn so far. A standard home loan provides the full amount upfront at settlement.
What is a progressive drawdown and how does it work?
Progressive drawdown means the lender releases your loan in instalments tied to construction stages like slab, frame, and lockup. Each release requires a progress inspection to confirm the work is complete before funds are paid to the builder.
Do I need a fixed price building contract to get a construction loan?
Most lenders prefer a fixed price contract because it provides certainty about the final loan amount. Cost plus contracts are harder to fund and usually require detailed cost breakdowns and contingency provisions.
What happens if my build goes over budget?
If construction costs exceed the approved loan amount, you'll need to cover the shortfall yourself or apply for a top-up. The lender will reassess based on the updated valuation and your current financial position.
Can I use a construction loan for a renovation?
Yes, a house renovation loan works similarly to new home construction finance, with funds released progressively based on the scope of work. You'll need quotes, council approval if structural changes are involved, and a clear cost breakdown.
