Actually made some progress this weekend - two ten hour days and almost finished the laundry wall.(got one row in above the door)
Up at 5 am both days and packing up in the dark at the end of the day.
It was a very slow process on the right hand side of the wall as multiple boards were required. The boards have to be cut back so that they join over a stud.
I made one mistake when fitting around the water heater pipes - there's an extra hole in the board - I'm hoping I can hide it with enough 'No more gaps'
The left hand side was fiddly on the first row when working around the plumbing, but quick after that - no joins - just a whole lot of boards the same length.
Tony M did a great job installing the corner stop timber piece.
