This is what I built, and donkey and pony field shelter half way up a mountain in deepest Wales. Pretty good views. I am not the worlds biggest fan of building stuff, but I enjoyed this. We were visiting friends who have opted for a rural existence and they'd just acquired the pony and donkey, oddly enough from the field next door to our house. So, a weekend of hard labour, good food, too much wine and the company of good friends. Plus, assorted children didn't fight, an added bonus.
If my four legged friends don't use it after our efforts, I'll show them what the French do to horses on our next visit
