    Thank you Granny Flats WA for the beautiful new custom-design home we have. With particular thanks to Jack our Site Supervisor, who kept a professional eye on everything and kept things moving along, we now have our Granny Flat in about 13 weeks since work began. The quality of the build is excellent, we are really happy with its look and feel. The promises that were made in the sales process were kept by the operational team, an important component of keeping our relationship with the company intact throughout the process. With thanks to all the team! Valerie and Curtis

    I highly recommend Granny Flats WA for their professionalism and quality of work. They completed our project ahead of schedule, and the build quality was excellent. The entire process was very well managed. A special thanks to Jack, the site supervisor, who was outstanding throughout the project—always supportive, responsive, and ensured everything agreed in the contract was completed properly. His professionalism made the whole experience smooth and stress-free. I would also like to thank Mike for his valuable inputs and guidance during the initial contract stage. His advice was clear and helpful, which gave us confidence right from the start. Overall, Granny Flats WA delivered exactly what they promised—high-quality workmanship, strong project management, and a professional team. I would rate them very highly and wouldn’t hesitate to recommend them to anyone considering a granny flat.

    Right from the start GRWA were a pleasure to deal with. Always responsive and willing to find solutions to any issues which arose. We went for an extension and bespoke build. The end product is a gorgeous 70m2, two bed-room villa blended in beautifully on my property. I would highly recommend these guys.

    We spent a lot of time thinking about which builder to go with and especially with the mixed reviews Online. In the end, we decided to take the leap of faith and go with GFWA As our needs, Council area, space restrictions required a bespoke design which was an attached extension limited with easement boundaries. From the beginning, Kathy was amazing and so patient With our multiple questions, managed the issues that emerged with planning but always kept fantastic communication with us. The Design team and pre-start were great and being under Jack and his supervision was the peace of mind worth paying for. All the team from prep of site works (Mitch, Anthony, Colin), frame up, cabinetry, plumbing and electrical gas painting. Small details and maintenance were just fantastic. Special call out to John and the boys-Felt very reassured in your skills over a few weeks and the chats, what legends you are! , Painter Christiaan and Ben, Mick, Alex Lawrence and Chloe and many others we may not have cross paths with directly. I’d like to leave a 10 star review but alas five stars is the Max! Thanks and blessed Christmas to you all.

    We had GFWA construct an addition to our home and could not be happier with it. From the planning stage all the way through to handover was great. All Supervisors, Trades, and suppliers who attended our home we're polite and friendly and the end result exceeded our expectations. Thanks, GFWA the end result is a credit to you all.

Frequently asked questions

How much do builders typically charge?
Builder costs vary widely depending on the job type and complexity. Minor repairs are generally much less than extensions, small builds or structural alterations that need foundations, framing or specialist input. Most quotes include a call‑out fee plus labour and materials, and the page shows live pricing to help you compare options.
Do builders charge call-out fees?
Call‑out fees are common and typically cover travel and an initial inspection or assessment. This fee is usually separate from hourly labour and materials, and after‑hours or weekend attendance often attracts higher rates. Ask whether a call‑out or minimum charge applies when requesting quotes.
Do builders need a licence in Australia?
Yes. Building work generally needs to be carried out by a licensed builder in every state and territory, and NSW builders are regulated by NSW Fair Trading. Builders should be able to provide their state builder/contractor licence number and show appropriate insurances and ABN/GST registration. In Victoria, domestic building insurance is required above a state threshold for certain contracts.
