So the neighbours in the next road but at the bottom of my garden have decided to build some kind of shelter and attach it to my garden wall. This now means it would be easier for intruders to gain access to the back of my house and would also stop me from building on the wall from my side if I wanted to which I think is unreasonable. Especially since they didn't bother to knock and ask if I would mind beforehand.
I'd like to go round there and question them, but do I have leg to stand on or are they just being cheeky?
