We’re so happy we went with Quality Granny Flats for our first build. After visiting the showroom and meeting Ash, we felt comfortable straight away. He really took the time to listen to what we wanted and made the whole process feel easy and straightforward.
What stood out the most was how genuine and honest he was. No pressure, just clear communication and support from start to finish. We felt looked after the whole way through.
The finished granny flat is exactly what we hoped for. The attention to detail was great, and Ash made sure everything came together just how we pictured it. You can tell he takes pride in his work.
We’d definitely recommend Quality Granny Flats to anyone looking to build. Great service, fair pricing, and someone you can actually trust.

Building our first granny flat was such a big step for us, and after meeting with so many companies that just didn’t feel right, we were honestly starting to lose hope until we walked into the showroom at Quality Granny Flats and met Ash. From that first visit, we knew we were in the right hands.
Ash made us feel so at ease. He genuinely listened to everything we wanted, asked thoughtful questions, and made us feel like our vision actually mattered. We’d been to other showrooms before, but none gave us the confidence and warmth that Ash did.
He went above and beyond, not just in the build itself, which turned out better than we could have imagined, but in the way he guided us through the entire process. There were no hidden costs, no pressure, and no stress. Just honesty, kindness, and real attention to detail.
It’s rare to find someone in this industry who truly cares and takes pride in their work, but that’s exactly who Ash is. We’ll always be so grateful for what he’s created for us and how smooth he made the whole journey.
We can’t recommend Quality Granny Flats enough. They’re the real deal.
