Attached is the view onto my block paved area of drive - my house is to the right. I am not sure what might happen yet and I am pre-empting what may happen just in case.
My neighbour in the property to the left has said about increasing the width of his drive - possibly taking out the border (The border is wholly his) including the trees and bushes. That is his right and I have no problem with that as I can do something on my property to compensate for this loss of greenery. However, what is not immediately obvious from the image is that the end near his garage is about 300mm lower on his side just where the paving curves around the back of the bush. There are paving slabs on end that retain my drive just here. If he removes the border and soil to the same level as the far end of the border is he obliged to install some form of retaining wall?
If this happens I will obviously ask what he intends to do, but I feel I need to be armed with something just in case. If a wall is not installed and my drive starts to collapse would he leave himself open to remedial work to my property?
