got an estimate on how much it would cost to add a bedroom? Would you also need a bath?

I am sure that something to help with the stairs would be a lot less expensive option since you love your house so much. There are so many new options now that I have been seeing advertised. I haven't looked at the costs yet, but the new stuff will probably come down in price as it gets more popular. I like the one that you just step on a platform, even with the floor on each level, and it glides you down to the bottom or up to the top. For some reason, it appeals to me more than the sit-down kind, but if one is sick, I am sure the sit-down kind would be more useful.
