Check out Doug's construction. It is going to be a shower and a dry compost loo. We were worried that it was going to be a bit of an eye-sore but it blends in really well and looks great. The sides are made from willow and the roof has a waterproof underside covered with birch that we had left over from our schooling fences.
We are picking up the Shepherds hut tomorrow. I must do some work now...
