When you're planning to build in the Hills District, the way construction finance works is fundamentally different from a standard home loan. You're not borrowing a lump sum on settlement day. Instead, funds are released progressively as your build reaches defined stages, and you only pay interest on what's been drawn down so far.
Progressive Drawdowns Match Your Build Timeline
Construction finance releases funds in stages tied directly to your build's progress. Your lender advances money at key milestones such as slab down, frame up, lockup, fixing stage, and practical completion. Before each release, the lender arranges a progress inspection to confirm the stage is complete. You submit an invoice from your registered builder, the inspection occurs, and funds move directly to the builder within a few business days.
This structure protects both you and the lender. You're not handing over the full loan amount before work begins, and the lender confirms that funds align with actual construction progress. For builds in areas like Castle Hill or Baulkham Hills where council approval timelines can vary, this staged funding also means you're not carrying debt on money that hasn't yet been needed.
Interest Charged Only on Drawn Amounts
During construction, you only pay interest on the portion of the loan that's been released. If your total loan is $600,000 and $150,000 has been drawn for the slab and frame, your monthly interest charge applies to that $150,000, not the full amount. As each stage is completed and more funds are drawn, your interest cost increases accordingly.
This can make a genuine difference over a six to twelve month build. Instead of paying interest on the full loan from day one, you're managing smaller repayments that grow in line with the construction itself. Most lenders structure these as interest-only repayments during the build, switching to principal and interest once the home is complete and you convert to a standard home loan.
Fixed Price Contracts Provide Certainty for Lenders
Most lenders require a fixed price building contract before they'll approve construction finance. This document locks in the total build cost with your registered builder and sets out the progress payment schedule. It removes uncertainty about what the project will ultimately cost and confirms that the loan amount will cover the work.
A fixed price contract is different from a cost plus arrangement, where you pay the builder's costs plus a margin. Lenders are cautious with cost plus contracts because the final amount isn't predetermined, which creates risk. If you're working with a custom builder in the Hills District on a unique design, confirm early whether they work on a fixed price basis. Owner builder finance is also more limited, as lenders view it as higher risk without a licensed builder managing the project.
Understanding the Progressive Drawing Fee
Each time funds are released, the lender charges a progressive drawing fee to cover the inspection and administration. This typically ranges from $300 to $500 per drawdown. Over five or six stages, that can add $1,500 to $3,000 to your total cost. Some lenders cap the fee or include a set number of inspections, so it's worth comparing how different lenders structure this.
The fee is usually deducted from the drawdown itself, meaning it doesn't require an upfront payment from you. But it does reduce the net amount that reaches your builder at each stage, so factor it in when confirming your budget.
Council Approval and Timeframes Affect Loan Conditions
Most construction loan approvals require you to commence building within a set period from the disclosure date, often six to twelve months. This condition exists because interest rates and your financial circumstances can change. If your development application or council approval in The Hills Shire takes longer than expected, you may need to request an extension or resubmit your application closer to your actual build start date.
In suburbs like Kellyville or Rouse Hill where land and construction packages are common, builders often manage the council plans and approval process. But if you've purchased suitable land separately and engaged your own builder, stay on top of the timeline. A lapsed approval can mean reapplying for finance, which may involve updated income verification and a new credit assessment.
Land and Construction Packages vs Separate Purchases
If you're buying a house and land package, the developer typically coordinates both the land settlement and the build. Your construction loan covers both components, with the land portion settling first and construction drawdowns following once the slab is ready to pour. This structure can simplify the process, as you're dealing with a single contract and a known builder.
Buying land separately and then arranging a custom build gives you more control over design and builder choice, but it also means managing two distinct processes. You'll need to settle the land purchase, then apply for construction finance once you have council-approved plans and a signed building contract. Some lenders will assess both together as a land and build loan, but timing is important. If you settle the land months before construction begins, you'll be paying interest on that portion without the offset of rental income or occupation.
Renovation Finance Works Differently
If you're planning a substantial renovation rather than a new build, the finance structure shares some similarities but with key differences. A house renovation loan may still involve progressive drawdowns tied to stages, but lenders will also assess the existing property's value and the expected value after renovation. The loan amount is based on the combined cost of purchase (if applicable) and renovation, and you'll need detailed plans and quotes from licensed tradies such as plumbers and electricians.
Renovation finance is particularly relevant in older pockets of the Hills District where buyers purchase established homes with the intention to extend or modernise. The same principles apply: fixed price contracts, progress inspections, and interest charged only on amounts drawn. But the approval process also considers whether the renovation adds sufficient value to justify the loan amount.
Switching to Principal and Interest Repayments
Once construction reaches practical completion, your loan converts from the construction phase to a standard home loan. At this point, you switch from interest-only repayments to principal and interest, and your repayment amount increases. The exact timing depends on your lender, but it usually occurs within 30 days of the final inspection and drawdown.
This transition is worth planning for financially. If you've been paying $1,200 a month in interest during the build, your new repayment might be $2,800 once principal is included. If you're also paying rent during construction, that cost drops away once you move in, which can offset the increase. But if you're holding onto your existing home or managing other commitments, factor in the higher repayment from completion onwards.
For anyone building in the Hills District, understanding how construction finance actually works gives you the confidence to move forward with clarity. The staged drawdowns, interest structure, and contract requirements are all designed to protect you and keep your build on solid ground.

Frequently Asked Questions
How does interest work during a construction loan?
You only pay interest on the portion of the loan that has been drawn down, not the full amount. As each construction stage is completed and more funds are released, your interest cost increases accordingly. Most lenders offer interest-only repayments during the build, switching to principal and interest once construction is complete.
What is a progressive drawing fee?
A progressive drawing fee is charged by the lender each time funds are released during construction, typically $300 to $500 per drawdown. This fee covers the cost of the progress inspection and administration. Over a full build with five or six stages, these fees can total $1,500 to $3,000.
Do I need a fixed price building contract for construction finance?
Yes, most lenders require a fixed price building contract before approving construction finance. This contract locks in the total build cost with a registered builder and provides certainty about the final amount. Cost plus contracts are typically not accepted as they create uncertainty around the final loan requirement.
What happens if my council approval takes longer than expected?
Most construction loan approvals require you to commence building within six to twelve months from the disclosure date. If council approval delays push you past this timeframe, you may need to request an extension or reapply for finance closer to your actual build start date, which could involve updated income verification.
Can I get construction finance for a renovation instead of a new build?
Yes, house renovation loans work similarly to new construction finance with progressive drawdowns tied to stages. However, lenders also assess the existing property's value and the expected value after renovation. You'll need detailed plans and quotes from licensed tradies, and the loan is based on the combined cost of purchase and renovation.
