First of all, my great praise that you worked analog in the plans, and then also right away with furniture templates to move around.
Due to the smoothing of the bay window line, the upper floor becomes a bit larger, for which the bathroom and one of the children's rooms (which would benefit from this without further changes) probably won't have use to this extent. Thanks for that too, because it excellently illustrates my advice to derive the ground floor from the upper floor instead of the other way around.
My surprise about the wall thickness simply arose from the fact that I do not know any manufacturer who even has this stone thickness in their range. There may be one, otherwise the planner would hardly think of using this format, but that would probably limit the choice of manufacturers already (?)
