Cost of hiring a builder

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. The below is a guide for quotes received for building projects, requested through Oneflare.

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 is considered highly specialised fields that require particular qualifications before undertaking any work. By working with an experienced and qualified builder, it will give you 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
