Those wise words reflect thoughts I've been having throughout. I've been toying with the phrases and friendly tone I could employ simultaneous to telling him that I don't want such heavy-duty fixings to my wall.

Ye could argue till the cows come home on that one (that's semantics for ye). https://bit.ly/3dsFqmb

Tony, thanks very much for taking the time to furnish me with your wisdom. He definitely sees this as a terrace and, presumably, carry out the same functions that a terrace would provide. He thinks he can use a variation of a loft-ladder for access from the back-gate steps. So, from what you say, the council is only concerned with structural integrity and they will have no mandate in terms of trespass? Is the bottom line that no work can be done to my wall without my permission?

It was clear from the conversation that he sees this as a terrace.

Comrades, my next-door neighbour happened to mention that, maybe next year, he intends installing decking over his wee back yard and possible over his single-storey extension. He said he intends to connect his joists to my extension (23) on one side and to his extension (25) on the other side of his yard - see image (joist indicated in orange). The image I've uploaded is from the own plans for my extension years ago. Do you reckon he has any right to do this if I don't want this structure attached to my house?
