Imagine having a ladder that goes to your attic that you can retract for easy storage, but this ladder is directly in front of a door archway which prevents the door from opening/closing as well as preventing people from being able to easily get in/out of the room. For the closet, imagine a small storage closet where half of its "floor" consists of a 45 degree incline rather than a horizontal surface because it was made directly on top of a staircase.
