  Granny Flats Australia is exceptional! My site was very awkward and narrow to build on, but Granny Flats Australia did a phenomenal job to complete a beautiful 2-bedroom granny flat, just like a mini-home! I had granny flats built by different builders previously, but in my honest opinion, Granny Flats Australia is the BEST by far! Good value, knowledgeable, honour their promises, professionalism, streamlined process starting from day 1 until completion, and good quality workmanship. That's why I am now building another granny flat with Granny Flats Australia! Many thanks to Rod, Norman, Michael, Felicity, Liz, Martin, Dani, Chelsey!! You are all truly amazing!

  For any Sydney siders considering building a granny flat, I would definitely recommend Granny Flats Australia. If you’re after a reputable and solution orientated company, want great customer service and want a smooth construction process but also be involved with the customisation of your mini home, GFA is the company for you! The entire process from start to finish was seamless and reliable. I’m happy with the final outcome and enjoyed the experience with GFA. I’d like to say thank you to the team, Rod, Felicity, Norman, Michael and Danielle - the team are valuable assets to your company and really make GFA standout. Felicity supported with transforming my vision into reality, and I commend her and the architect/engineering teams for their agility and problem solving with making the limited space work (51sqm is the size of our granny flat). Norman was great during pre construction and during the external builds, he was thorough and kept me well informed about all the works to be done and was helpful with his recommendations. We were then handed over to Michael, who’s an absolute gun! He ensured works progressed timely and smoothly, communicated clearly and even offered to help if we noticed any defects after the keys were handed over. My only feedback would be to provide clearer explanations during the material selection process, especially when it comes to custom or add on materials. I originally selected a splash back panel that was an add on, however was notified during the last stages of the project that the company hadn’t worked with the supplier’s material before so they couldn’t guarantee warranty or final finish of the splash back. This is understandable, however I would have appreciated if this was communicated up front during the material selection meeting and to work through alternatives earlier on instead of deciding last minute on secondary options, which were done close to completion of the project. Thankfully we managed to land on splash back tiles that we were satisfied with, so thanks Felicity for working through this with me.

  We had a fantastic experience with Granny Flats Australia while building our owner-occupied granny flat. From the beginning, Rod impressed us with his extensive knowledge and realistic approach to the quote. As the project progressed, we had the pleasure of working with Liz, Martin, Norm, Michael, Chelsea, and Danielle. They consistently surprised us with their seamless teamwork, timely communication, and prompt responses to all our queries. The quality of the work exceeded our expectations, and we couldn’t be happier with the final result. Highly recommend!

  A big thank you to the Granny Flats Australia team. We are very happy that we chose them for our project. Some things that could have been done better: response time for questions about material selections, knowledge about passive solar design, high performance windows and low VOC paints, setting expectations for when the project would begin and communication around the timeline of milestones. Some things that were awesome: initial meeting at showroom to discuss project, creation of initial quote, friendliness and responsiveness of reception staff, friendliness of all workmen and staff on site, cleanliness of site, responsiveness of external and internal construction managers, and the actual end product/workmanship. The team were also helpful with aspects of the job that were related to our project, but not their responsibility, such council contributions, tree removal and damage to our property caused by the skip bin operator. Some things that the pre-construction team could start doing: advise clients on passive solar design and high performing materials that promote a low energy footprint. If we ever decide to build another one, then I would absolutely consider using them again and will recommend them to our family and friends.

  I just wanted to thank the team for the wonderful experience they provided. Their effort and support truly went above and beyond. As with any build, unexpected challenges came up, but they were consistently on top of everything and handled it all with professionalism. The architect was especially impressive, he modify the floor plan to suit exactly what I wanted. This company delivers a truly bespoke and high quality service, both in their workmanship and the products they use. The attention to detail reflects prestige and care at every step. A big thank you to Rod, Martin, Norman, Michael, and the rest of the team. I’ll definitely be recommending your company!
