Building a custom home typically costs between $3,250 and $5,000 (or more) per square metre (m²).

We include everything under a ceiling, including alfresco areas, porches, etc. It’s a broad estimate for establishing potential costs and should only be used as a ballpark figure.

Every custom project requires its own timeline. Typically, a detailed custom home can take 9–12 months (or more) to complete.

At Primebuilt, we take the time to understand your needs and guide you through each step, regularly communicating what’s required during pre-construction, construction, and post-handover stages.

By consulting with a team experienced in delivering similar projects. At Primebuilt, we have a step-by-step process that starts by setting realistic expectations for your project budget, based on past data. We guide the development of your project plans throughout the design phase, ensuring success and the delivery of your forever home.

Get to know your builder—you’ll be working closely with them for 12–18 months or longer. Interview them, check online reviews, and ask for references from previous clients. Your builder is a critical partner in your project and should be approachable for any detail, large or small.

You’ll enter into a building contract with your builder. There are two common payment methods:
1. Progress Claims: Payments are tied to milestone stages of the build (e.g., 15% at the completion of the frame stage).
2. Cost Plus: Used for projects where a fixed price is hard to calculate, such as complex renovations. Costs are billed periodically, with an agreed percentage for builder overheads and profit.

Variations shouldn’t be a dirty word. A good builder will have provided a detailed proposal, clearly outlining what is and isn’t included. When variations are necessary, they should be logical and easy to understand offering flexibility to adjust the scope during the project.

A quote is a 1-2 page often vague document. We like everyone to be on the same page and have no surprises. That’s why we engage first up in a pre-construction program where we get to know you and that results in upwards of 70-80 pages of detailed information about your future home.

By this stage, we’ve delivered on our promise, and a lasting relationship has formed. We offer complimentary checks at 3, 6, and 12 months to address any minor issues like a loose screw or sticking door. We also offer a maintenance program for ongoing support, such as gutter cleaning and window maintenance.

Success largely depends on thorough planning. While we can often start sooner, projects that lack pre-planning and proper scheduling may face delays and incur extra costs due to last-minute decisions. It is common that any time saved cutting corners in pre-construction is quickly lost and often at a cost of both time and money.

Once Project Estimates are established, we encourage you to speak to a lender as early as possible. Ensure they agree with your builder’s payment terms and ask how long they will require to approve your loan once the building contract is signed.

Interior designers play a vital role. They provide up-to-date product knowledge, practical advice, and help visualise your design, which is invaluable for those struggling with decision-making.

Primebuilt offers a selection service to help with fittings, fixtures, and colour choices. While this service doesn’t include the visuals or documentation of a full interior design service, it connects you with our supplier network and is ideal for those happy to browse showrooms independently.
