I have a tri-level house and want to open up the kitchen to the family room and dining room but I am not sure if the walls are load bearing. I have a picture of the walls. The wall that does not go all the way to the ceiling was put in by me 11 years ago, that was to divide the dining room from the family room, I know that is not load bearing. It's the walls perpendicular and parallel to the vaulted ceiling. The perpendicular wall never spanned the entire length and there is not another wall on the opposite side of the vault. Just on that one are of the vaulted ceiling.
