I'm not too much of a designer, but I know it gets annoying. I had moved from the starting house, where the fire meter was near halfway, to a 2 story house, and the meter was way over half when I got there, since decorations I never really used were everywhere. It would be kind of bad though, having a ton of stuff in the house could lag the game when loading. Still it is kind of bad the way it is right now.
