If master bedroom is downstairs, would you prefer having your kids rooms on the first floor or second floor? I have babies now so I feel like it would be easy to keep an eye on them and safer with no stairs for them now, however when they're teenagers I wonder if we'd all appreciate the privacy of being a bit separated. I'm still debating one or two story and can't decide which way to go because we want to stay in this house long term. Which do you prefer? Also, what did you convert your playroom to after kids were older?
