My wife and I currently live a SMALL story and a half house. We are considering adding a master bedroom in what is now the unused, unaccessed attic. I have a small room that I would like to put the stair case in but I am not sure how much room I will need to do this. The ceilings are 8' in the room where I would like to put the stair case. My questions are: How much room do I need for a stair case? And what other considerations do I need to take in my plans? I think I have everything covered, but????
