What an amazing experience.we had Nick and the team in to carry out an extension and they surpassed every expectation. We are so happy with the finished job we highly recommend them to everyone that asks us if we know a builder.

He did an amazing job extension on my Daughters house that we had him to come and do our extension. He's a really nice guy, very trustworthy and reliable. He did a wonderful job - planned it and gave really great advice. He's currently using him again to do another job. He's reasonably priced - so impressed! .

Nick can put his hands to all jobs and completes the work to a very high standard and cleans up when he's done. He is a fantastic craftsman and reasonably priced. My neighbours have also use Nick and we have recommended him - will definitely use him in the future.

Nick has done several projects for us from a full attic conversion to the most recent installation of 2 media walls. Re routing the kitchen cupboards and knocking through to make a big family room. Always clean work. No obstacle is an issue and always happy to help with ideas and solutions. Nick is very skilled and respects the homes of people he works in, this quality can’t be underestimated.
