Living room: 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 living room in particular, the sofa takes the whole room and nothing moves around it.
What seeing it first changes
You see the result before you start, so you know what to start with. What moves is the sofa, the rug and where the TV goes — the walls, windows and doors stay exactly where they are.
