I have a doorway that had odd sized double doors and the rough opening is 48.5" x 80". I need to make the RO 32" x 82.5". I can't be sure that the wall is not load bearing. It is an interior wall that was added about 5 years ago, but at the same time, the attic was finished into a bedroom, so I suppose it's possible that this wall now helps support that. The header is made by two 2x4's sitting side by side from jack stud to jack stud, rather than stacked, and there are 3 cripple studs. How do I go about reconstructing this into a 32" x 82.5"?
