Mike and his team were great to work with, clear communications from the outset, and work of a very high standard. Nothing was a problem, and Mike found solutions to everything that needed solving throughout the project. Would highly recommend.

– Garage conversion

My brick wall fell down due to the recent storm and I called in prestige building to carry out the work I was really pleased with the final result there was good communication throughout the job from Mike and consistent amazing work I definitely recommend to anyone for there building and landscapes jobs that need completing.

I am so impressed with mike at Prestige building. We first got a quote last year but couldn’t go ahead due to planning. Mike had so much patience with us and even helped us complete some of the paperwork. When we were finally ready to go ahead with the extension he was able to give us the date we planned. He was able to give us advice on the build. We had subcontractors in and all involved did the job quickly and efficiently. Everything was planned in time perfectly. We are so happy with the results. We can’t recommend Mike enough. I will continue to use him time and time again. Thank you
