Many of today’s space-conscious designers have all but eliminated single-flight stairs. Instead they favor stairs that are U-shaped in plan, with two flights and a landing, because they take up less area. This does indeed save space, but it makes it impossible to carry an 8-ft. sheet of drywall upstairs.
An old builder I know suggested that I score the backside of the sheet at the 4-ft. mark, fold the two front faces together gently and then take the doubled sheet up the stairs, unfold it and screw it in place. This works like a charm, and the extra taping involved is negligible. Most 12-ft. sheets will negotiate stairs this way as well.
