Hi my parents own a farm and at the far end of the land is on old farm house and its outbuildings. These buildings were struck by fire over 20 years ago and have laid to ruin since. Some of the walls still exist to approx 6 feet in places. However it has become rather overgrown. The area is classed as greenbelt (it’s not in the middle of the countryside you can see a housing estate from the plot, but the proposed building could be positioned behind the trees so they cannot see us!). I know its highly unlikely that we would get planning permission to re-build the original barn or farm house. Therefore do i need planning permission to build a log cabin here and if so would i be more likely to get this rebuilding the abandoned farmhouse, (i could class is as a holiday home if this helps). Or would I be better trying to get permission for a static caravan? Thank you
