new floor screeded to same height as kitchen. All areas will be covered with durabase and an additional 6mm insulation over the kitchen. So the only difference in height will be the insulation and the adhesive for it - some of which will be compensated for in the new room by the high points.
Hence our guesstimate of an average of 8mm over whole area.
