Groundwork & Foundations- 1 May 2026
Richard and team are absolutely one of a kind! They can do absolutely anything you can think of! It’s the first time I’ve used MyBuilder and to find Lionheart Builders, I’ve hit the jackpot! They completely put my mind at ease, very professional and knowledgeable. The work was completed to a very high standard and not to mention they are very reasonably priced too!! We’re definitely keeping their contact details for all of our future jobs and will recommend them to all our friends and family. Thank you both for such an amazing experience!

If I could give Aaron (the owner) more than 5 stars I absolutely would! Impeccable service from start to finish. I found out about AGF through a friend & when approaching them I was impressed by the quotation given to us for the amount of work that we needed doing, thought maybe it was too good to be true at first, but it wasn’t - we certainly bagged a bargain! High standard finish to our property for a fraction of the price my neighbour paid for hers, she even commented that ours look much better than hers do, bonus! Aaron was professional throughout and is a lovely & down to earth person. We asked if we were due a roof replacement due to a leak we had, he was honest and told us we already have a good quality roof that just needs a small repair, I’m sure many tradesman would have jumped at that opportunity to overcharge us for something we didn’t need, but he didn’t do that & was honest in his advice throughout & carried out the work to a high standard. I was impressed that as the owner that Aaron does the main bulk of the work himself, in my experience the owners tend to leave the grafting to the employees but he gets stuck right in there and is definitely a perfectionist with his work. He’s informative to his clients and answers questions (and I had many questions), he’s pleasant and friendly and even had the approval of our 4 year old who never talks to anyone! The work was completed in a timely manner, to a perfect standard, for a great price. He even did extra for me like using leftover cement to stick back a step on the front garden that had come loose, plus other small jobs. Absolutely lovely guy who goes above and beyond for his customers, and I’d certainly recommend him to anyone. Will definitely be calling him back for anymore work we need doing. If you’re looking for a builder and in 2 minds about how to choose - choose this one, you won’t be disappointed! Thanks Aaron!

Extensions- 12 Feb 2025
From the first communication with Stewart this has been the most easy and amazing process.. I honestly can't praise him and his whole team enough. The process has run so incredibly smoothly and quickly it's been amazing. It's difficult choosing a builder and we worried we would choose the wrong one, worried about how it would go..but we choose the best option. I would highly recommend Chez Construction to anyone looking for builders. It's taken around 3/4 weeks give or take from start to finish. Stewart was always on the end of the phone to respond to any questions wr had and dealt with the architect and council for us aswell. We are very very happy with our new extension.

Extensions- 2 Jul 2019
We would highly recommend Greg of Extreme Construction. We hired Greg after looking at several local builders and posting the job on MyBuilder. Greg was quick to respond to questions and listened to what we wanted to achieve. His quote was very competitive and after following up references which he was happy to provide we hired him to complete our extension. We certainly made the correct decision, from start to finish he’s been excellent, on schedule and budget. The extension has been finished to a high standard and we are very happy.

Mark was able to start the job at very short notice and dealt with some unexpected additional work along the way. The work was carried out promptly and to building control standards. Communication was good and I would use him again for similar work.
