As it was a nice sunny day I managed to get the front wall done. First job was the bottom rail, I drilled through the concrete and fixed it down with 4 10mm x 175 mm anchor bolts then made a frame to attach the wall boards, I've put silicon in between the joints just to make it extra water tight.
Just a pair of doors to make now ( when i get some more wood ).
Here's a couple of pictures for Norm to look at .
