Can I pile within 3 metres of a neighbours boundary wall? The wall does not form part of a building but is a normal land dividing wall approx 1m high with a fence on top. I've looked online on the governments acts but they seem to relate to a party wall like a terraced house for example. I have started piling on site and a neighbour has asked us to stop because there is no party wall agreement, do I need this just for garden wall which I think is probably owned by the neighbour?
