The walls go up.

A simple stud wall can be built very quickly, so after spending a bit of time sorting out a couple of little details the back wall was ready.

The structure is EX 4 x 2 CLS studs sheathed with 11mm OSB I have decided to screw the studwork together as it so much stronger and easy to take apart in the event of a mistake. The back wall went straight up and was held with a few temorary braces. As always it looks much bigger than when it was just the foundation area and certainly much higher so we will have some serious tree puning to do next week.
