Hallway: first home
It is your first place and you are starting from nothing.
What gets in the way
Everything needs doing at once, and the order you buy in matters as much as what you buy. And in a hallway in particular, it is a dark corridor where coats get dumped.
What seeing it first changes
You see the result before you start, so you know what to start with. What moves is the storage, the mirror and the light fitting — the walls, windows and doors stay exactly where they are.
