Understanding Land and Construction Finance
A land and construction package lets you buy vacant land and fund the build under one loan structure. The loan settles when you purchase the land, then releases funds progressively as your builder completes each stage, meaning you only pay interest on what's been drawn down rather than the full loan amount from day one.
This differs from a standard home loan because lenders assess both the land value and the proposed construction. They'll want council approval, a registered builder with a fixed price building contract, and proof you can service the loan once construction finishes and repayments switch from interest-only to principal and interest. Most lenders require you to commence building within a set period from the disclosure date, typically six to twelve months, so timing between land settlement and construction start matters.
In Hawthorne, where vacant blocks are rare and often positioned on sloping sites near the river or backing onto bushland, lenders pay close attention to whether the land is classified as suitable for standard residential construction. If your block requires retaining walls, significant earthworks, or sits in a flood-prone zone, some lenders will either decline or require a larger deposit to offset perceived risk.
What Lenders Assess Before Approving Construction Finance
Lenders evaluate the land purchase price, total construction cost, your deposit, and whether you can service repayments once the build completes. They'll also review the builder's credentials, the building contract, and council plans to confirm the project is viable and the finished property will be worth more than the combined loan amount.
You'll need a fixed price contract from a registered builder, not a cost plus contract, because lenders won't fund open-ended builds where the final price isn't locked in. The contract should include a progress payment schedule that aligns with the lender's progressive drawdown structure. If there's a mismatch between when the builder expects payment and when the lender releases funds, you'll need to cover the gap from your own resources or renegotiate terms before settlement.
Consider a buyer purchasing a 405-square-metre block in Hawthorne, zoned low-density residential, who plans to build a two-storey home designed to suit the sloping block. The land costs are at the higher end due to proximity to Oxford Street cafes and Hawthorne Park, and the build cost reflects the need for split-level construction and a suspended slab. The lender requires a 10% deposit on the combined land and construction value, plus evidence the buyer can service repayments based on the completed property value, not just the land. The buyer also needs to show they have enough savings buffer to cover the gap between progress payments and drawdown timing, which in this case meant holding back an additional amount in offset to manage cashflow during the six-month build.

How Progressive Drawdowns Work During Construction
Funds release in stages as construction progresses, typically after a progress inspection confirms each phase is complete. Common stages include slab down, frame up, lockup, fixing, and practical completion. The lender arranges the inspection, charges a progressive drawing fee for each drawdown, and transfers funds directly to the builder once satisfied the work matches the stage claimed.
You'll pay interest only on the amount drawn down, so after the first drawdown your repayments are lower than they will be once construction finishes and the loan converts to principal and interest. Some lenders allow you to make additional payments during construction to reduce the balance before conversion, while others restrict this depending on whether you've chosen a fixed or variable construction loan interest rate during the build.
Timing is important because builders often invoice before the lender releases funds. If your builder requires payment within seven days of reaching lockup, but the lender takes two weeks to arrange the inspection and transfer funds, you'll need to either negotiate extended payment terms with the builder or cover the amount temporarily. In our experience, this is where buyers with a modest savings buffer after paying their deposit can run into trouble if they haven't planned for the lag between builder invoices and lender drawdowns.
Choosing Between Construction-Only and Land Purchase Combined
Some buyers already own land and need construction loans to fund the build alone. Others are purchasing land and building in one transaction, which requires the lender to assess both components and settle the land purchase before construction starts.
If you already own the land in Hawthorne, the lender will value it as part of your deposit contribution, which can reduce how much cash you need upfront. However, if you bought the land years ago and it's increased in value, some lenders will only recognise the original purchase price rather than current market value when calculating your deposit, depending on how recently you acquired it. This varies between lenders, so if you're sitting on land that's appreciated, it's worth comparing how different lenders treat existing equity.
If you're buying land and building together, the lender settles the land purchase first, and you'll start paying interest on that portion immediately even though construction hasn't started. Once the build begins, drawdowns occur progressively and interest accrues on each amount released. This means your repayments increase incrementally throughout the build rather than jumping to the full amount at completion.
What Happens If Construction Costs Exceed the Approved Amount
If your builder invoices more than the lender approved, you'll need to cover the excess from your own funds. Lenders base their loan amount on the fixed price building contract and won't increase the facility mid-construction unless you formally apply for a top-up, which requires re-assessment and may not be approved if your financial situation has changed.
Variations during construction are common, whether due to design changes, unforeseen site conditions, or material upgrades. The builder will issue a variation order, and you'll need to pay it outside the construction loan unless you've built a contingency buffer into your original loan application. Some buyers include a small buffer when they apply by rounding up the construction cost estimate, though this only works if the valuation supports the higher loan amount.
In a scenario where a Hawthorne buyer upgraded kitchen fixtures and added a covered deck mid-build, the variations totalled an additional amount not covered by the original contract. The lender wouldn't increase the loan because the valuation was already tight relative to the approved amount, so the buyer paid the variation from savings. If those funds hadn't been available, the builder would have either delayed the variation or required the buyer to remove it from the scope.
Fixed Versus Variable Rates During Construction
You can choose a variable construction loan interest rate, a fixed rate, or a split during the construction phase. Fixed rates lock in your repayments during the build, but if you want to pay down the loan faster or make additional payments during construction, a variable rate offers more flexibility.
Some lenders let you fix the rate during construction and then revert to variable once the build completes and the loan converts to principal and interest, while others require you to choose one structure for the entire loan term. If you're building in a rising rate environment, fixing during construction can provide certainty around repayments as each drawdown occurs, but it also means you'll pay break costs if you want to refinance or sell before the fixed period ends.
Interest-only repayment options are standard during construction because you're only paying interest on what's been drawn down, and the loan balance increases with each progress payment. Once construction reaches practical completion, most lenders automatically convert the loan to principal and interest repayments unless you've arranged to extend the interest-only period, which typically requires re-approval based on your current income and circumstances.
Approval Timelines and Conditional Requirements
Construction finance takes longer to assess than a standard home loan because the lender reviews the building contract, council plans, and builder credentials on top of your financial position. Expect conditional approval to take one to two weeks, with final approval dependent on satisfying conditions like providing the signed building contract, proof of council approval, and evidence of insurance.
Some lenders require you to have a development application approved before they'll issue formal approval, while others will provide conditional approval based on the DA being lodged. If your Hawthorne block requires a DA due to building height, setbacks, or character housing overlays, factor in council approval time before assuming you can settle land and start construction immediately.
Once approved, the lender will issue a disclosure document with a validity period, and you'll need to settle the land and commence building within the timeframe specified. If construction delays push you beyond that window, you may need to reapply or request an extension, which isn't automatic and depends on whether your financial circumstances and the lender's credit policy have changed since original approval.

Frequently Asked Questions
How does a land and construction package differ from a standard home loan?
A land and construction package releases funds progressively as the build reaches each stage, and you only pay interest on what's been drawn down rather than the full loan amount from the start. Lenders assess both the land value and the proposed construction, requiring council approval and a fixed price building contract before approving the loan.
What happens if my builder invoices before the lender releases funds?
You'll need to either negotiate extended payment terms with your builder or cover the amount temporarily from your own savings. Lenders typically take one to two weeks to arrange a progress inspection and transfer funds after each stage is claimed, which can create a timing gap with builder invoices.
Can I fix the interest rate during construction?
Yes, you can choose a fixed rate, variable rate, or split during the construction phase. Fixed rates provide certainty as each drawdown occurs, but variable rates offer more flexibility if you want to make additional payments during the build.
What deposit do I need for land and construction finance?
Most lenders require a 10% deposit on the combined land and construction value, though this can vary depending on the lender and whether you have existing equity in land you already own. You'll also need a savings buffer to cover the gap between builder progress payments and lender drawdown timing.
What if construction costs exceed the approved loan amount?
You'll need to cover the excess from your own funds, as lenders won't automatically increase the loan mid-construction. Variations due to design changes or unforeseen site conditions are common, so some buyers include a contingency buffer in their original application if the valuation supports it.
