Honestly, I don’t need a window in the dressing room either, just as little as a door so as not to disturb the other person. We didn’t have that in our apartment before either and we still love each other
So you didn’t have a dressing room in the apartment. You didn’t need one. Then you don’t need a dressing room today either.
The point of a dressing room is to get the wardrobe out of the bedroom in order to:
a) not disturb the person in the bedroom
b) separate the bedroom from the hallway (walk-through dressing room) to create a “parents’ area”
c) keep the bedroom visually “nicer”
For turning on the light, there are motion sensors, okay, but have you ever noticed that colors look completely different under artificial light than under natural light? For example, under the dreadful cold-white LEDs.
Just think about whether you really need a dressing room like the one in the above design. Because it takes up space! Without it, child 2 would also have space for a large wardrobe like child 1 and you would also have the same wardrobe space in the bedroom. I don’t see exact measurements in the design, but with wardrobes on both sides as drawn, it won’t work. We have 2.15m width in the dressing room (shell measurement) and that’s just enough for two 60cm wardrobes (corpus size, plus 3cm for the door) on both sides.
