I had a few quotes done for the job of converting my workshop into a well-insulated and usable room and although Aeron's actually wasn't the cheapest he was very honest and told me that some of the work I'd requested wasn't actually necessary so he actually saved me money. I have to say with all sincerity that Aeron (and Dave) are by far the best tradesmen I have ever hired. Absolutely outstanding craftsmanship, excellent work ethic, friendly, pleasant and efficient. 100% confidence in recommending.

The end result was outstading and carried out in a very professional manner. The space we were working with was awkward and there were no bedroom/ wardrobe specialists who could create something in the space we had. Dom had one initial site visit and took all measurements down before completeing the work off site. The wardrobes, drawers and shelves were then fitted in one day. What was created looks as though it has always been there which is superb given the space he had to work with. Well recommended.
