Not much help to me. I suppose I could buy a few lottery tickets, see if I can get lucky too.

You don't want an exposed edge of the floor slab with the ability wick damp into the inner floor.
Mike might have a different solution but I'd be thinking of a strip foundation maybe with steel rebar, dwarf walls with DPC 150mm above ground. An internal insulated slab floor with DPM under tucked into the DPC all round.

Out of interest, what is the thinking behind the 50mm?
Any thoughts on vapour barrier + plasterboard or osb and plasterboard?
