Maybe it is no longer of interest, but: Our (purchased and not planned by us) house has a very similar floor plan. The upper floor is completely identical, the dressing room is a work corner for us. The ground floor is mirrored, and since we have a basement, your utility room = our office and your office = our kitchen (open to the living room with French doors). I find our floor plan almost perfect for 4 people. Only the hallway is too narrow for me. You cannot greet or say goodbye to another family together without crowding. And shoes should have a place near the door, otherwise dirt is actually carried far into the ground floor. The living room across the entire width of the house with windows facing south is great. And the clear layout on the upper floor is simple, timeless, and functional. I also do not find the bathroom too big. We are happy about that. Apart from the fact that I would never build without a basement, I find your design very practical for everyday life and appealing.
