I am planning on knocking a wall down between our kitchen and dining room. Got a SE in and he has confirmed that it is not a load bearing wall. However, he has indicated we need a wind post on one side to deal with lateral forces e.g. wind. I pointed out that this wall is the party wall with our neighbour (semi detached house and the wall in question is where we are attached). He said that this is required in case the neighbours house was ever taken down. Very unlikely but he tells me this is what the regulations say. Sounds a bit mad but equally wouldn’t be surprised by anything in regulations! Does anybody know if this is correct as I can’t find anything regarding this particular situation?
