Out block is in a new estate and our neighbours block is a metre higher than ours and there is a limestone retaining wall which sits on their side but on the boundary.
We have found out that they have had plans approved to build their garage wall which is 9 metres long, on the boundary line which means this is being built on the retaining wall.
Council will only tell us that it applies with r codes but we have concerns about the extra load the retaining wall will be taking. I have driven around everywhere looking for a similar set up and haven’t found one and haven’t found much online about this set up.
Their builders engineer has stated the retaining wall is sufficient but it seems a bit strange that they can just build a brick wall on top as it is. There is an expansion join in the retaining wall right under where the wall will be.
Has anyone done this before? And have photos or information on how it’s done. While the thought of a 4 metre high wall on our boundary isn’t appealing, I’m more concerned about the bedrooms we will have next to it and how safe that wall will be long term.
