    I had the absolute pleasure of dealing with Faraj on a recent project to build a granny flat, and I couldn't be happier with the experience.From the very beginning, Ferrage stood out with his fair and competitive pricing. What really set him apart, though, was his commitment to transparency. He took the time to walk me through the entire process, highlighting potential challenges and providing clear explanations every step of the way. This level of openness was incredibly reassuring.One thing that truly impressed me was Ferrage's attention to detail. He personally inspected the site and thought deeply about the best ways to approach various aspects of the project to ensure it was in my favour.

    This is a really great company for anyone that is new to the entire process of wanting to build a granny flat on their land. The customer service they provided is second to none. Sarah, who initially answered my phone call was lovely and was really open to answering all my questions. To top it off, Faraj’s professionalism and honesty is what will keep me in contact with them. His willingness to work with us prior to purchasing our property and providing his expert opinion with a fast turn around time is more than what I expected. I’m grateful that I decided to contact these people and confidently encourage anyone to do the same if wanting to build a granny flat.

    Faraj’s approachability and professionalism is what brought us to the company. His experience in the industry ensured a smooth sailing process. He reviewed site maps before we had even purchased our property, worked through with us what we wanted, what was possible and what wasn’t when it came to drawing up plans and remained with us during the construction process and thereafter. We are beyond ecstatic with the outcome and are grateful that we had someone we could confidently rely on and turn to in unknown territory.

    We used Blue Gum Granny Flats for our build and could not be happier with them. Their team of sub contractors and employees are very dedicated to providing the best possible product without question.. We were kept updated during the build and as each part of the build was progressing they kept us one step ahead so it went very smoothly. Nothing was a problem at any time. All the building material is very high standard along with the internal inclusions and we always had the choice to change or upgrade any part of the build. They are a great team of people dedicated to providing an excellent finished product and we would recommend them very highly

    Chris , Sarah and the team have done an outstanding job in the creation of our granny flat. Chris provides realistic expert advice when creating a concept from scratch and helps achieve the best possible outcome for the client.My wife and I are very happy with the final result and could not recommend Blue Gum Granny flats enough. Their professionalism is unlike anything you would expect from the average builder. Great communication in particular the weekly updates from Sarah which outline the status of the build.Thanks!

    I built two granny flats at the same time as I found their quotations were very competitive. Received Their professional attitude at every step of the building process including design. Communications (Weekly updates by Sarah) were very good and always upfront. Comparatively took very short time to finish (4 months including 4 weeks Christmas break). I am very impressed with the quality of service. I can say staffs were very responsive and well managed by Chris and William. Their honesty really impressed my whole family and recommend highly Their professionalism. If myself and any of my family members want to build granny flats or extension of our existing houses, certainly will contact Blue Gum again. Thanks Guys for your super service.
