If you’re thinking of building a home, you might need a loan to do so. That's where construction loans come in.

Construction loans differ greatly to a normal home loan thanks to something called progressive drawdown.

Check out our guide on how construction loans work:

What is a construction loan?

A construction loan is a specific type of home loan designed to assist the funding of a new home’s construction. Getting a loan for a home that doesn’t exist yet can be a bit trickier, so a construction loan works in conjunction with the building process and helps you pay for it. 

Construction loan interest rates are typically higher than standard home loans, as it's harder for a lender to value a home that doesn't exist yet, raising the level of risk. Additionally, they tend to have higher valuation fees, as the lender has to do a valuation at each stage of the construction process.

How does a construction loan work?

So how do construction loans work? Construction loans function very differently to a standard home loan. They typically charge interest-only repayments for the duration of the build, which is usually set at 12 months. This is to keep your repayments to a minimum during construction, before reverting to a principal and interest loan at the end, known as the ‘end loan’. 

An even bigger difference between construction loans and home loans is how your repayments are calculated. A standard home loan charges you interest on the full loan amount, but a home construction loan divides your loan into stages based on what part of the building process is occuring, a method known as progressive drawdown or progress payments.

How does progressive drawdown work?

A loan drawdown process typically consists of five or six stages:



% of total build cost


Paying the builder to begin construction

Up to 10%


Concrete slab complete or footings 

Approx 10%


House frame complete and approve

Approx 5%


Windows/doors, roofing, brickwork, insulation

Up to 35%


Plaster, kitchen cupboards, appliances, bathroom, toilet, laundry fittings/tiling etc.



Fencing, site clean-up, final payment to builder


This is a rough example and should be taken as such. If one of these stages (such as the base) costs $100,000, then for the duration of that stage you’ll only be charged interest on that $100,000.

If you then draw down an extra $100,000 to pay the builder for the next stage (the frame), your repayments will now be based on the interest costs of $200,000. So essentially, funds from your approved loan amount are only charged interest as they are paid to the builder (drawn down).
