Not much experience with the scottish building standards but would presume a 60 minute wall would suffice. This could be single skin block (but would not help the sound resistance flanking transmission) to a stud wall 100*50mm studs with 1 layer of 12.5mm plasterboard either side (some insulation would also help i.e. 100mm fibreglass)
