I recently built my 2 bedroom granny flat in Blacktown with the Granny Flat Experts, and I find the team very efficient, accommodating, and carrying quality conscious approach in work. They use high quality products, have a great planning and design team with phenomenal customer-oriented approach that I could rely upon. They were quite accommodative of my requirements at every stage, and listened to me as a customer. George has been a remarkable person to work with, very patient and supported me for any consideration during the entire phase of the project. Taylor and Peter have also been excellent resources to rely upon the project. Overall, I find the team at Granny Flat Experts and the company to be honest, efficient, ethical, customer-centric, quality- focused, and reasonable priced without compromising the standards. All my friends who visited my place have admired the built quality and the look and feel of the Granny flat. I definitely recommend George and the team for any Granny flat projects and they are truly Experts in the field, as the name says.

We recently had the pleasure of working with The Granny Flat Experts for the construction of our two bedroom brick granny flat. From our initial meeting with George at the site visit, through to the design planning, the contract, the payment plan and the handing over of the newly built granny flat, we were very happy with him, his team and the process. The all inclusive price for the build and the appliances was competitive, reasonable and affordable. The progress payment schedule was clear with no hidden costs. George and his team at The Granny Flat Experts take great pride in their work, which showed in their professionalism, communication, efficiency, workmanship and quality materials. A special mention and thank you to Taylor, our Project Manager. Taylor was lovely and amazing to work with. She was always ready to answer our questions, follow through with any concerns and working towards a solution to suit both parties. We would not hesitate to recommend The Granny Flat Experts to family, friends or anyone planning to build a granny flat. Thank you George, Taylor and team at The Granny Flat Experts. Corinne & Tony

If you're planning to build a granny flat, I highly recommend The Granny Flat Experts! Best price, best team, and top-quality results! I contacted around 10 granny flat builders across NSW, and finally chose George because of his patience, approachability, and proactive attitude in solving our concerns. He offered a highly competitive quote while ensuring the highest quality of construction. As the Managing Director of the company, George is extremely experienced. Our backyard had many challenges and was not an easy site for building a granny flat, but he came up with practical solutions and helped us overcome every issue. He also helped us redesign the layout to better suit our needs and made smart suggestions for improving the existing plans. His building team worked efficiently and paid great attention to detail. They completed our granny flat in just a few months as promised in the contract, with no delays and excellent workmanship. If you’re looking to build a granny flat, The Granny Flat Experts is a name you can trust — best price, best quality, and total peace of mind!
