I can't seem to find a definitive answer to this..maybe someone here knows? My neighbour put up a field shelter last year in a field adjoining ours. He has never had livestock in there but has used it for storing his landrover, trailer, wood and a J.C.B. We recently had a falling out over an access issue that he lost, and, within days I found 250 withies planted at the bottom of my garden bordering the stream and now his J.C.B. is parked right up against my fence blocking my view. I expect it will remain there for the foreseeable future as he never uses it. It's the storing / parking of vehicles permitted on agricultural land?
