I'm adding a new wall/door in a current finished loft space to convert it from a loft to a bedroom. I've already decided to trim back the carpet and carpet pad to attach my bottom plate to the subfloor properly, and of course trim back the existing baseboard.
What is the correct way to install the top plate and first stud of each side?
- Leave existing drywall - Attach the top plate to as many ceiling joists through the drywall as possible and the side studs to potentially nothing except the new top/bottom plates
- Remote existing drywall - Attach the top plate directly to the ceiling joists and side studs to the existing top/bottom plates and any studs that overlap in the existing walls.
