I had a very good experience with Jamatek Design Studio. Initially I wasn't aware and ignorant of planning rules regarding building an extension for my home in Cardiff but the team took me through it all and were very professional in their approach. They helped and worked with us all the way to the completion of our extension which looks amazing! Most times, you don't get such personal service from big companies so it was refreshing working with the team at Jamatek.
