Hello everyone. Im in the process of designing my house with home designer suite and am having a problem with my loft area. I need the whole interior wall to be open, as I plan on having a staircase follow the 1st floor wall and a railing across the whole 2nd floor wall. Right now I have an attic wall, and an exterior wall on that side of the loft set behind the attic wall. I feel like I should make the attic wall invisible, but what do I do with the exterior wall to keep it from coming down through the roof line?
