How to set out a garden room base using the rod system

I said I was back! pumping out these videos as often as I can now. John has concreted the rods in with Adam and Davey. Me and Jen have returned to do the serious stuff! John, Im joking!! Its a team effort as always, and here you'll see how we put the base in which will support the full structure of the room. No fingers were broke and we all went home safely. Blood, sweat and tears definitely go into these rooms. Please comment, subscribe and like or thumbs down if it does not register with you😏
