You have to be completely obsessed with it for real. You can't fake obsession. There's no compromise possible. You keep looking until you find the place that will work for the story. And that holds for the objects, too.
Many places are painted or rearranged, new furniture is brought in.
You cant make compromises. Compromises kill the film. That part is free. You'd do that no matter what. You get paid to deal with idiots who don't care about movies.
