i'm actually in a building that is somewhat of a hole in the building code, although i'm assuming it's well over 400 m^2. well, a quick calculation took it way over...

there's all kinds of rules about where you are and aren't supposed to put a furnace. it's supposed to be in a fire-separated room - ruling a kitchen out. unless it has "vertical separation" (which i doubt), in which case you can use a sprinkler. it's supposed to be a good distance away from bedrooms and living rooms, meaning where it is is no good. there's supposed to be separation in the flooring (which was just eliminated by cutting the holes through the floor).
