I dont know if it makes any difference but Id be slightly tempted to do the wall insulation before the floor dpm and floor -only because if any moisture gets through the wall -it will run down to the slab and not the floor.Thanks, yes I was always planning on using a plastic layer as well.
does the rest of my plan sound ok to you?
Am I right in saying you are having on walls: a 50mm wall cavity, then 50mm celetex then plywood?
I think on a solid external wall, it might be better to put 50mm insulation tight to the wall, with all gaps filled and the joints taped and if you want cover with VCL. Then fix 50 x 25mm battens flat and screw in place through the insulation -then fix plywood to the battens.
If you google "internal insulation of solid walls" I think this is the recommended method.
Wall insulation types: solid and cavity wall insulation
I would definitely insulate the pillars as they made of Hi 7s -they will be cold.
it might be a good idea to put a vertical dpc where the doors are -a length of 100mm dpc would so, folded so it creates a say 70mm x 30mm corner -tape in place at the doors, put insulation in place then clad with plywood -afterwards cut off any dpc poling out in front of the plywood. Why do that? -well if you get any driving rain that gets through between door and frame, it will hit the dpc and run down and cant make the ply damp.
