Turning an otherwise unused large attic space into a bedroom or game room is a great idea to create more living space in your home.
However, if you are considering creating a bedroom in an attic you will probably need to sister new lumber, such as 2x6s or 2x8s to the existing ceiling joists. If the ceiling joists are on 24” centers then you should also add new ceiling joists (floor joists) in between the existing ceiling joists. These steps are extremely important when converting an attic into a formal living space. The additional lumber will help to ensure the new bedroom floor won't flex and/or cause cracks in the ceiling drywall below the attic.
Check with your local building inspector to determine your attic’s specific framing needs prior to beginning construction.
