Ok, we will think about it again, personally I would probably have left out the separate room downstairs, but my girlfriend wants the separate room on the ground floor also for old age to use it as a potentially necessary bedroom, I rather think that in case of emergency one could use a stairlift. The alternative ground floor layout would then be usable again and the utility room also a bit larger. The toilet arrangement works for us as it is.
True, on one side they are not planned very deep, the question is, do you need a window in the dressing room? Or maybe reduce the window size. The longer side should have at least 60-70cm deep cabinets, the other side probably 40cm ones are enough for small stuff.
