But, it only lists repair and making good work. Grade 2 listed status applies to the inside too, if they were planning on using it for something, I am sure they would need planning permissions of some sort for the inside, of which there is none. Fairly substantial work would need to be carried out inside too for it to be used for anything, as it is in a bad state, this would need planning permission. This says to me, the repair work being carried out is just that. Repair work. Work to keep the structure from detonating even further.
I could be wrong and I hope I am, I would love to see something there. But there is nothing in the application that supports this, and it would need to be in their due to its listed status.
