Good morning and thanks again for the suggestions. I am happy to address your points, since "my" floor plan in this case is really supposed to appeal to me, I have actually already thought about your mentioned points in advance, but of course that does not mean that for someone else these points would not be the clearly better / more practical choice!
Number 1 regarding the bedroom, I just want to ask the group directly, how often are you daily in your bedroom/dressing room? For my part, usually in the morning to get up and in the evening to go to bed... I liked the idea of the en-suite bathroom, conversely, I would personally find it less nice if guests always had to first pass through or past the bedroom to get to the bathroom. The large bathroom is generally used anyway by me, the family, and overnight guests, that was my consideration behind it. Expanding the hallway for that... no, since you also need a corresponding depth e.g. for the walk-in shower with the heated towel rail... And regarding the topic of gastrointestinal problems... there is always the guest toilet, so I do not see that as a problem at all.
Number The guests enter through the front door, not through the garage. As you can see, the back wall of the shower is recessed a bit, here a wall panel along with a shoe cabinet will be installed. Furthermore, a dresser for miscellaneous stuff will be placed on the right side wall next to the storage room, which I will use as a pantry, even though it was once labeled as such, hence the open door to the living room/kitchen.
Since the utility room is quite spacious (intentionally), there is enough storage space here for shelves/cleaning supplies and the like, so I find the solution to use the storage room as pantry better.
But as I said, some considerations could certainly be implemented for other configurations... Thanks again for the comments & have a nice day everyone!
