However, to fit Minecraft correctly, I think it could be kinda more complex than the real-life "versions". Here, the pics are attached below, so you can see what I mean.
We could have many options of frames to put on the doors. As the first option, We could have 1-sided frames, which would be placed on the same side/position of the door.
We could also put the frame on both sides.
And as a last alternative, we could kinda "tunnel" up the whole door passage.
It'd be more of an aesthetic mod, so the doors should look nicer and prettier than just standing at a blank wall without some decoration.
