What a journey, we managed to find a granny flat specialist who not only built but designed the flat to our specifications, and managed to squeeze it in the site, using skill and tenacity, and fire walls!!It started slowly, with the joys of the permits, but once that was done it went quite quickly.And yes with every project there were challenges, however they were dealt with quickly and smoothly.A major factor for us was having good, quick and clear communication , which was always the case.All in all a great job and would recommend them to others.Thanks

We cannot fault these guys at all! They’re friendly, approachable, and understanding. By far the best tradies we have ever had attend our property by far! Their workmanship is second to none and they actually clean up after themselves! Huge thanks to Paul and his crew for not only the job you did but always respecting us and making sure the end of the day the yard was still safe for the dogs. Huge thanks to Simon for everything you accommodated for as we know it was a battle for a bit there.If you are considering a granny flat for your granny, your kids, or somewhere to escape from said kids - these are the guys you want! 10/10 without question!

We have recently completed a build with Superior Granny Flats, and couldn’t be happier! From initial consult to finalisation, the communication between all teams was calm, clear and constructive. Superior organised all council permits here in Ballarat, and were knowledgeable about the changing laws within Victoria at the time.The design team took our personalised concept drawings, and made these a reality, listening clearly to all the quirks we wanted within the build.We were concerned starting a build, after hearing horror stories that have circulated over the last few years, but have nothing but praise for the team at Superior. On behalf of my family, we would like to thank Simon, Ryan, and all the workers who came on site, for their professionalism and respectful attitude throughout the project.We have already recommended Superior to two friends who are looking to build in the near future.

Superior built me a Granny Flat 300kms north east of Melbourne. Even at that distance nothing was too much trouble for the company. I cannot compliment the Management, staff and subcontractors enough. Everyone was very professional; keeping me informed of progress, answering all my questions, and completing the build to high standard.I would recommend Superior to anyone who is thinking of building a Granny Flat/Cabin etc. Cost wise they even compare very favourably.

Peter Tully

We engaged Superior Granny Flats to build a small granny flat and unusually to also renovate concurrently a room that was an enclosed carport - attached to the existing house - and used as a spare storage room.The Granny Flat layout is based on affordable range Option 1 but built to their Superior Range standard. It comprises a large bedroom, more than big enough for a king bed, a bathroom - shower and toilet - with space for a washing machine and dryer and a walk-in-robe. The renovated room consists of one half being a kitchen with space for a fridge, sink, dishwasher, stove and microwave, ample bench space, in addition to cupboard space for pantry and cutlery etc. The other half of the room is a lounge area big enough for 2 recliner chairs and coffee table, a television and split system both mounted on the wall.We elected to do this approach as the size of the block of land was limited, but its location was great for access for shops, schools and transport. The end use was for us (2 people) to use the Granny Flat and the renovated room, the original main house being used by family (2 adults and 2 children).The result is high class. The finishes for both areas are exceptional, especially the internal room as it is unrecognisable from what it was. The team of trades that Superior Granny Flats have are all first rate and were at all times professional and fielded queries about the build.We are very happy with the end result and would highly recommend Superior Granny Flats for any of their wide range of Granny Flats.Peter and Julie

Would definitely recommend Superior Granny Flats! The whole process from the day we walked in, to handover was easy and we were looked after and consulted the whole time. Simon made the whole process easy and adjusted things along the was as we requested. Nothing was too hard! All the team worked so hard to finish the unit and have mum in before Christmas. We are really happy with the finished product and absolutely recommend Superior if you need that extra space.

Our experience with Superior Granny Flats was seamless. Once council planning permits were issued the communication with the team and length of time to implement the build and finishing was very quick. They were happy for me to suggest changes to the colour and finishes. We are extremely happy with the end result.
