    DPC/DPM in wall below external ground level.

    Yes that did cross my mind. But I was planning on using the first row of ties starting just above the dpc. I presumed the first 6/7 rows of bricks below the dpc would be ok without any ties.

    Warm Deck flat roof - vapour barrier

    Yes it's something like that. Ok so if I don't need the decking on the joists, then how would I install the vapour barrier? Would the vapour barrier go straight on to the firrings and the insulation boards on top of that? Or can I staple the vapour under the joists before I put the...
