Chris, the reason why i asked is, my brothers girlfriends parents are pretty loaded, Her dad got about 5 fields with the house they bought but he cannot get planning permission for them even though there is "stables/workshops" at one end. these fields are huge, approx 6 football pitches side by side.
I wouldn`t of thought a bit of asto/dirt/cobbles etc would require planning permission as it would always be changing so therefore not a permanent fixture?
At the moment these fields are making him no cash so a couple of hundred quid a week is better than a kick in the nuts for him.
