Never Ending Story.
Limahl. My youth :-)
Would the whole thing be easier to realize if the children's bathroom is placed next to the master bathroom and thus the gallery is eliminated? The children's bathroom then becomes the dressing room.
The gallery is – to answer Krüger’s question – not art, but can be removed. But otherwise, you are in the wrong movie regarding the approach. You won’t bring it into congruence by shifting walls. As I said: take a look at the old plan, after all it is the origin of this floor slab. Then write on each drain what it was originally planned for. In the extreme, take all the sanitary fixtures from the old plan 1:1, i.e., the kitchen and the bathrooms with all objects, and make only the walls towards other rooms subject to change. In the next step, vary the locations of the sanitary fixtures under the condition that they still connect to the same soil pipe. I still see you coming to the realization to adopt my opinion of your floor slab (at least a doctoral project for an engineer, if not a damned devil’s gift).
