I'm looking to build a wall in the basement. Basement exterior walls have concrete ledge so I'm planning to build a wall in front of it to build a straight wall floor to ceiling. I have couple questions:
Since the exterior wall is already load bearing, the new wall in front should not be load bearing right?
If the above is true, then can I frame the wall with screws and not nails? And can I use a 2 x 3 instead? Sole purpose of this wall is to hang drywall from floor to ceiling.
