Is hiring a builder worth it? 

In short, yes. 

You want to build a home or home extension that will be compliant with local regulations and last for decades to come. It’s important, then, to choose a builder who is skilled, qualified, honest, and trustworthy with the job. 

Even the most skilled DIY’er will struggle with certain aspects of building a new home, so finding a professional builder is key if you want a stress-free and hassle-free build.

But here’s the catch, not all builders are built the same. To help you separate the average from the exceptional, we’ve rounded up some of the factors that influence price.

Factors determining the cost of building in Fairfield 

The overall cost of a builder depends on many factors, including: 

The builder’s hourly rate

Builders in Australia generally charge anywhere from $70-$120 an hour depending on their skill, specialty, and level of experience.  That said, choosing a highly experienced builder will ultimately cost you less money (though it’s a higher up-front investment) as you are less likely to have mistakes, rework, or quality concerns. 


If you live in a more rural or out-of-the-way area, it will be harder to get materials and labour to your space. This will lead to higher overall builder costs. 

The nature of the work

If you’re looking to build something new, it will have a different final cost than if you are remodelling an existing space like a bathroom renovation or kitchen renovation. When considering this factor, think about whether or not you need things like plumbing, wall construction, wood work, and furniture. Every element that you need will factor into the final cost.

The types of building services you require

 If you do need services besides building, it’s important to remember that each professional will charge additional rates. Plumbers and electricians, for example, generally charge $75-$125 an hour. Carpenters and glazers, similarly, charge $60-$100 an hour, and cabinet makers and tilers charge $50-$80 an hour. 

The materials you use

Clearly, luxury materials will cost more than basic installations. The same logic can be applied to the design, as a complex design will often be more costly to build, while a straightforward design can incur less cost.

To know where you fall on this table, it is important that you understand your own needs. Ask yourself: 

  • Do you need to raise and restump your home? 
  • Are you extending or renovating your home? 
  • Is your property eligible for granny flat construction? 
  • Do you want a completely new build? 

Answering these questions for yourself ahead of time will help you have a clear number range to work with when you start conversations with potential builders. 

What questions should you ask a potential builder? 

Once you’ve asked and answered your own questions, it’s time to start interviewing builders and looking for the right team for the job. 

To know if you’re dealing with the right professional, ask questions like: 

“What’s the cost breakdown?”

 Generally, you should expect about 50% of your total costs to go toward materials, while 35% should go to labour and 15% should go to council fees and approval. Make sure that the builder you’re interviewing has a similar breakdown, along with an overall clear sense of price ranges and expectations. If they don’t understand the numbers at the start, it’s a good indication that you’ll have budget problems throughout the project – and that’s never a good thing. 

“What type of building do you specialise in?”

 It’s always best that you choose a builder that has a lot of experience with your kind of job. If you need to restump your house, for example, you should choose someone with extensive experience on many restumping projects. Ask a potential builder, then, what they specialise in – and make sure that you get the references and examples to back up what they say. 

“Can I see your licence and insurance?” 

Any prospective builder must be able to show you that they have the right credentials. Make sure that their licence and insurance are valid and up-to-date before you continue any conversations. 

“Do you have any customer references I could see?” 

Reputable builders will have a long list of happy clients, and they’ll be happy to give you those references and reviews. If they’re not, it may be a sign that there’s something they don’t want you to know about their work style or their previous jobs – and that’s never a great sign in this industry.
