BE CAREFUL, I watched something on this the other day, someone bought land, but the local council were shats, country boys who were determined to come down on them like a ton of brick.s

Basically, if land has planning potential, then it is not cheap, the big boys will know about it and get it way before anyone else, and it will take internal backhanders for councillors to give out planning permission. This would be something you would never see, old boys clubs/networks

You may get lucky, but, i would imagine the best way to do this is to buy land that has a non listed run down residential building on, then pull it down and build a new place.
