Living room: empty flat
You just got the keys and there is nothing in it.
What gets in the way
An empty space cannot be pictured: with no furniture, you cannot judge a size, a colour or how you would move around. And in a living room in particular, the sofa takes the whole room and nothing moves around it.
What seeing it first changes
You see the room furnished before buying anything, so you stop getting dimensions wrong. What moves is the sofa, the rug and where the TV goes — the walls, windows and doors stay exactly where they are.
