I have an extension which is 130mm bigger than the 3 metre limit (terrace house).
The planning are on my case.
Do you think I could run a grinder through the side wall, separating the outer course of brick from the back wall, thus making my extension, 3 metres with a rear garden wall only a few millimeters away.
I know it would leave only 1 course of block for the back wall, but planning are not being nice.
Any advice would be great.
