In the house I'm buying, the neighbour's double garage forms the left hand boundary of our garden.
I was thinking about putting trellises or something on it, to break up the brick and make the garden nicer.
Obviously the neighbour owns the garage (but he can't see this side of it at all) - would I need his permission to attach anything at all to it? Also painting it may look nicer, more than happy to ask permission but also worried consent could be refused and I'm stuck with an ugly wall to look at!
