I have space under the basement staircase that I want to make a proper room with door. On one side I have a concrete block wall, so there is no issue there and I can put a door in the front. But on the other side I cannot put drywall because existing studs are not aligned and metal post supporting the beam is outside the stud.
So can I solve this by adding additional studs on either side to the existing studs (sister stud)and the put a drywall on it? Or any other ideas?
