Hi, we moved into our house 2 years ago. It's a detached property but just a walkway distance between houses. The left fence is our responsibility according to deeds, however this fence is attached to the neighbour's house and follows their property line which is lower than ours. Also, the neighbour's have things up against a lot of the fence and their plants growing through it. This past week, one of the panels just "came out" and they want us to fix it. I would like a whole new fence but following our property line not theirs. Are we in our rights to just leave the existing fence and build a taller one on our property. Also, can we have it 2 metre tall on our side even if it makes it taller to them on their side? Hope this makes sense!
