So, name changed as obviously outting as pretty sure this isn't a normal occurance!
My neighbour has drilled a hole in my (grade 2 listed) building so she can permanently hang a piece of tarpaulin about 15ft up (as high as my 1st floor roof) for "privacy". Surely she can't just do this? Where do I go from here? It blocks all the light out to my ground floor windows now. Have included (bad) diagram.
