Doors can be built to open in four ways: inwards or outwards, hinge on the left or right. (Sorry if the language is wrong, non-native speaker here.) Considering that I am not sure I can follow why the door would make one direction more natural than the other. Maybe because there were more right-handed people than left-handed which made one setup more natural than the other?
Often the room itself gives you reason to prefer one direction or another. If the door is in a corner you want the open door to be against the wall (unless you don't - I can't think of why, but...). If there are other doors on the same wall you need to consider them - sometimes hinges all the same for symmetry; sometimes opposite so the the doors don't bang into each other (when they are right next to each other.
