The height on the upper floor as planned is completely fine. Since we do not have two full stories and the rooms are not that large, it works for us. Currently, the walls are plastered and the substructure is in place. The substructure will now be removed again and readjusted. The current problem is that we need to fit insulation (5cm WLG 035) between the substructure. The contractor is currently calculating whether a 3cm WLG 032 insulation can be installed. This way, we might be able to gain some height.
