can place stuff, just doesn't quite know about object dimensions yet so everything
get stuck together.

potential issues involve picking which GameObject when furniture gets referred to.

for now, just go in order i guess, until things can't be placed anymore.

in this simple demo case, it shouldn't matter anyway as there's only 3 objects.

need to get dimensions of objects.

how do objects get created initially?

center of method needs to get created.
at some point want to move those methods to room?

how to treat the floor and walls -> dummy objects that don't get written out at the end
