We are trying to finish an above garage attic space as a playroom (since the ceiling will be slanted - 7' to 4' headroom). The "room" is 25' x 8' and currently has 2x4s that are 16" apart.
My current place is to double up on the 2x4s by sistering them before putting a 23/32" plywood subfloor, topped with a light laminate or vinyl floor.
Is that a good plan? We don't intend to put any significant amount of furniture in here.
