How much do Builders cost?

$10,000 - $130,000

    How much does a Builder Cost?

    Builders are normally hired for longer-term projects that usually involve a higher cost than many other jobs. Whether you’re building a new house from scratch, planning a renovation or an extension, there’s more involved than you may think.

    While the price range and median price of building jobs in your state will matter, it isn’t the most indicative of what your particular project will cost. Building a new home from scratch will obviously cost significantly more than adding a simple home extension. Choice of features will also factor into the final cost in the end.

    Below is the average cost per hour for a builder in different states around Australia.

    State Average Cost per hour
    NSW $45 – $55
    VIC $35 – $45
    WA $30 – $40
    SA $35 – $45
    QLD $35 – $45

    How to Hire a Builder

    References are of more importance when it comes to building or construction jobs. They’re a relatively hefty investment so you want to be sure that the business you hire for the job is the right one for you. A good way to obtain references is to look through past customer reviews on their Oneflare profile, or alternatively, ask them for some photos of past work they have completed.

    Industry Experience
    Industry experience is more important than you may think. A builder with a great amount of industry experience will often have a sound understanding of local codes, zoning laws, and project management; all indicators of quality and efficiency.

    Education: Certificate III
    Building and construction are considered highly specialised fields that require particular qualifications before undertaking any work. By working with an experienced and qualified builder, it will give you the ultimate peace of mind with regards to safety and reliability. In Australia, a builder is qualified to work as a skilled tradesman or contractor when a Certificate III is obtained after completing a four-year apprenticeship. They can also gain a qualification through school-based apprenticeships which include off and on the job training.

    Registered: Building Practitioners’ Board
    For the builder or contractor to carry out any construction or building project valued over $5,000, they must be a registered member of the Building Practitioners’ Board. Additionally, they must gain approval from the Board to obtain a building permit for your project

    Are They Verified
    If they have the verified badge on their Oneflare profile, this means they have provided an ABN and are a legitimate business.
