i’m not suggesting to just do it without telling anyone im saying do not have plans altered as it will block any future ability to just build on that area.
To go down the route of adjusting plans changes what you have an then you would need to re apply for permissions to build something.
I am about to be going through this myself as we have buildings up we do not need at present and also a large area where building use to be and we were told to not chance plans as we are in a designated no new buildings area. As our land is also tax free as the dogs we home have full access to every area we also pay no tax on that.
@Anna we are about to remove old chicken houses and when we get round to it it will be turned into a cattery there is nothing stopping you using the building for anything else such as say storage sheds, so long as you dont try to turn an agricultural building into a house.
If you change the plans on the land register so it is no longer there it is like it never existed. As with anything on “agricultural land” most part you cannot make it into a human habitation without permissions but its quite easy to turn it into say a workshop or swimming pool changing as they are not classed the same as a habitation unit.
As I said (maybe ill add a few more words) Tell marie your taking it down but may have plans to do something later with it. Do not get it removed from plans is my advice
