Granny Flat Solutions recently built a 2 bedroom granny flat for my investment property. The whole process from sales to design and then construction was smooth and professional - I am very happy with the final result!
James, the sales representative, was very knowledgeable and came to do a site inspection and provided a detailed quote very promptly.
Tony and Matt, our project managers, were always very responsive to our emails and calls and kept us updated with the whole project. They made sure that any minor issues were quickly resolved and sent us weekly updates. GFS made sure to push the

Five years ago, we had decided to build a granny flat in our back yard, visited few granny flat builders around the greater Sydney but couldn’t find the right builder. This year a friend introduced Granny Flat Solutions. The management and staff warmly supported us from day one, signed the contract, stated the work and despite all obstacles and restriction caused by Covid 19 pandemic, completed it timely.
Though they are a big builder with many projects, their approach is like a family business it is personal and specific. The top managers, project managers, subies, internal architect, technical

I chose Granny Flat Solutions to build an extension/addition to my existing house plus an attached granny flat, just because of the company’s good reputation, being a multi-awarded company and the excellent reviews by their customers. I was not disappointed because they delivered on their promise, rightly deserving of awards! The project was completed almost hassle free, from the design right through the construction process, up to the handover, they were right on schedule except for a few weeks delay because of COVID. I am so pleased with the completed project, proudly showing it to my friends

Granny Flat Solutions were great! I got them to build a granny flat that worked out so well, a year later I got them to build another. I found them professional and punctual.
Highly recommend them for design and build of your Granny Flat.

6 stars! GFS built us a superior quality granny flat at an affordable price.
Our independent building inspector viewed at prelining and PC stages and was super impressed with the workmanship.
Shout out to Neil that designed a beautiful and unique granny flat that found cost effective ways to deal with a sloping block. Sean our PM was in regular contact with us and gave really thorough updates with photos of the site. He did a great job at also keeping our tenant in the main house informed who stayed for the duration of the build. Joseph was fantastic with helping with the bank on any financing

I would highly recommend Granny Flat solutions. They built a granny flat for us and the whole team from the sales person, designer, project manager, office team, trades and owners were fantastic and very professional. The finished product is excellent. They manage the whole process for you with council etc and they let you know of all costs upfront so you are prepared for council fees and other extras. Even with COVID shutting construction down for a couple of weeks they kept us updated and then the trades were back as soon as they could be. If you are thinking of building a granny flat this is

Granny flat solutions built me a great Granny flat on a difficult terraced block. My designer Neil did a great job to make it fit on the block and yet be functional and stylish.My project manager Pierre was great ,always one step ahead and in tune through a difficult time with covid temporarily shutting the industry down.I was particularly impressed with how fast things got up and running again when construction resumed.The brick work and painting were exceptional and puts our main dwelling to shame! It’s probably why they have won so many awards.Despite their excellence they were not the most

We would have no hesitations in recommending Granny Flat solutions. Stuart was our first point of contact who showed us around quite of a number of their completed and partially completed flats. Once we had made our decision we then dealt with Sean, our Project Manager, easy to deal with and provided us with weekly updates. From the office staff to those who worked on site we would like to say thank you. All work went well and completed within the specified time. We are very happy with the finished project.

Granny Flat Solutions recently completed a Granny Flat for me at Normanhurst. The experience from start to finish has been rewarding at every stage and memorable for all the right reasons.
From the initial consultations to determine what would best suit my budget and my difficult backyard, all the way through to the construction stage which was carried out in a manner which had minimal impact on my home and lifestyle, the staff at Granny Flat Solutions were exemplary.
The constant upfront communication made me feel at ease and confident with what I was signing up for and there were many instances

We are extremely pleased with our experience with Granny Flat Solutions. My husband has a background in project management and knows the ins and outs of the construction process. The quality that Granny Flat Solutions produced was highly detailed and attentive. We knew early on that we had chosen the right company to take on our project.
We were genuinely surprised by the level of professionalism that GFS brought to us - from slab, to carpentry work, to the finishing details.
Our designer, Khai was extremely helpful and gave us lots of great ideas and practical advise to get the most out of our
