Oh, I remember. Considerable resistance to advice:
Upper floor: Utility room far too small, access to the bedroom via the dressing room rejected.
Enlarging the hallway without changing the position of the rooms is quite easy: enlarge the exterior walls on the upper floor.
Joking aside: What else is possible:
Light in the hallway: make the window in the dressing room bigger and then add clerestory windows in the wall to the hallway.
