I own a top floor apartment with a roof terrace. A couple of months ago a new neighbour had a satellite dish installed on the wall of a community area adjacent to my terrace (ie a party wall) - and it is positioned so that it extends/hangs over my terrace - and looks pretty bad! I have asked him to move it - he agrees that it looks bad but says there is nowhere else it can be positioned. Now I'm wondering what my legal position is if I want to get this dish removed?
