Stringer Staircase (Umbrella Term) — Layout variation
Category: Layout variation
Umbrella term for stairs carried between two lateral stringers — includes housed, saddled and freestanding variants.
The stringer staircase is the classical form of a wooden staircase: the treads are carried laterally by two load-bearing stringers that frame the flight and transfer the loads to ceilings and landings. Depending on how the treads are joined to the stringers, there are mortised, half-mortised, slide-in, notched and saddled stringer staircases. On the wall side, the stringer is called the wall stringer; on the open side, the free or light stringer. Stringer staircases are constructively robust, can be built in nearly any plan form and form the basis of many modern and traditional stair variants.
