Sorry to start another thread about sheds. I'm having a few snags with the council at the moment and wondered if anyone has any advice. A few years ago I built a small 'lean-to' shelter in my garden to store my pushbike and a few garden tools under. It is basically four wooden legs with a piece of corrugated plastic on top. It's about 3x2 metres in size and sits around 2 metres high at it's tallest point. It has no walls and can be moved around easily if required. My **** of a next door neighbour has taken a dislike to it, she has tried over the years to get me to take it down by reporting me to the District Housing Office and even our local MP. So far they have all agreed with me and do not consider it to break any rules or regulations. This morning I received a letter from the planning department stating that I needed to submit planning permission for my 'permanent structure' or legal action would be taken against me. This came as a surprise. Clearly my neighbour has reported me to the planning department. So where do I stand? What constitutes a 'permanent structure'? My property is a leasehold, groundfloor flat with a large garden, like I said the shelter is completely moveable, it has no walls and it's fairly small. In my opinion it is no more than a piece of garden furniture. My understanding is, if I wish to store a piece of corrugated plastic in my garden and four pieces of wood, I may do so in whatever manner or arrangement I please. Finally I understand that if a structure has been up for over four years, they can't make you take it down. My structure has not been up that long, but my neighbour or the council have no way of proving this. Is it worth telling the planning department that I put it up over four years ago and to go swivel or shall I go down the route of attempting to prove that it is not a permanent structure? Any advice on this matter would be much appreciated. Also any decent (legal) revenge tactics wouldn't go a miss.
