Luke did a garage conversion for us and we are very pleased. He and his trades were professional, considerate, tidy and very efficient. Luke communicated with us and was completely trustworthy. AND the job he quoted was good value and did not change. He ended up doing some extra (paid) bits for us on request. We would highly recommend and use him again.

Serious and hard working. Since 1998 in EU and from 2010 in UK . "Work smart not hard" . Some people think they will get from you what they want with force. Some people forgot from where they leave and who they are!if they don't get what they want from you will denigrate you and try to put you down in front of other people. I look for quality not quantity!I respect people as long they respect me!
