Hello, SoI’ve been dreaming up a small home on a small plot. Sadly the neighbour has encroached to prevent (its a complicated story) but they have essentially pinned my little garage in and taken 2 feet of my land and is essentially attempting to force a sale. ...for now I need to repair the garage before everything in in is ruined. What can I do without planning permission for now until I have resolved the boundary situation? This is a case of someone with money taking of advantage of someone without....very frustrating! Please help. Thanks, Micc
