Hoping for some clarification please.
Our next door neighbour has installed a tall wrought iron gate to close off the side access to their house. Our house wall runs alongside their side return and they have no fence or their own wall. The frame of the gate is drilled into their house wall on one side and flush against our wall. It hasn’t been drilled in but they have used the wall of our house to essentially ‘wedge’ the other side of the frame. Doesn’t look like there is any damage to our house.
Should they have asked for permission from us as they are using our property to enable the gate installation. I’m not sure we would have refused but I would have liked to understand what was being done first.
