Our neighbours are proposing a rear single storey infill extension to their property: it's a terrace adjoining ours. The plans show the new side wall of the extension to be set back 6 inches from the property boundary line (our fence). The height will be 3 metres, brick built, flat roof.
What is the minimum set back distance required in order for them to excavate and build the foundations without encroaching beyond the boundary line?
If we refuse permission for them to access beyond the boundary line (even temporarily) for the purpose of building the foundations, what are their options, other than to set the wall back further? Can we refuse such permission?
