The door has a swing radius that is used for entering and exiting. It is not suitable for placing furniture.
Exactly why you don’t put anything in the room within the radius. In the study it’s still relatively okay, because the door is centered in the room. In the bedroom, however, the door is bothersome. And nothing gets placed in the hallway, so it doesn’t matter there.
There’s a reason why doors open inward: it reduces the risk of accidents, not with bikes, but similar to the dooring accident of the residents when they move upstairs. Collisions are avoided by keeping the rather narrow communal hallway clear. When entering and exiting. Let me put it this way: Child 2 gets the door leaf from Child 1 slammed in their face.
Since one child gets a sliding door and the other a swing door, it makes no difference there. The swing door goes both ways anyway.
The children’s bathroom and the study would be the two possible ones to run into, the bedroom is at the end of the hallway. That is unlikely.
Emergency responders trying to rescue residents from fire or other situations are not helped either. Or rather, the person to be rescued suffers here.
That’s actually the first reason I’ve heard for the change that can’t simply be argued away.
Fortunately, it’s “only doors” — if it actually turns out to be a problem in everyday life, it’s a comparatively simple change. (Switch/room controller position is still the hardest part, but that can be remedied with preparatory wiring.)
