Happy Family with their new Granny Flat


  • Helen and I can’t express to you all enough how happy and amazed we are with the beautiful Granny Flat you have built us. We distinctly recall getting serval quotes and seeing several sample flats and we believed GFA seemed the most professional and after speaking with Sandra, who was genuine and sincere, we knew GFA was the team to trust with our new home.

  • I would like to start off by thanking the team for their professionalism along the journey of the granny design and construction. The team is committed with strong customer focus. In the present moment, I’m considering granny flats Australia for my next project. Hands down, if anyone was to ask for a great team who will work for you to achieve any desired granny flat solution, there is no hesitation to mention the team I dealt with.

  • I just wanted to take the time out to say thank you for building my granny flat and making the whole project perfectly seamless. Everything flowed beautifully from the first visit to the showroom where I was given undivided attention by Sandra and Cid as well as the girls at reception. Cid helped me come up with the development idea that would work on my block. At no time did I feel pressured to sign up to anything other than what I wanted a 50 square metre granny flat even though a 60 square metre flat could have worked as well. Sandra’s advice with material selection was invaluable and it all looks fantastic.
