I?ve removed a few bricks from the party wall with next door, and noticed they don?t seem to use their loft - I don?t see them going in there and there?s only a few boxes of junk in there, some suitcases, chairs, and Christmas decorations. I regularly go in my own loft as it?s been converted to an en-suite bedroom. As they don?t similarly use theirs I was wondering if I went in there and started using it regularly for extra storage if in a few years I could claim it as my own additional loft via adverse possession?
