A Quarter Turn staircase changes its direction to the right or left, but the affected portion of the turn introduces a quarter space landing or winders. The flight of stairs turns 90°, as it rises to connect two different levels, so it is also called a L-stair. L-shaped Stairs have many advantages; they provide a visual barrier between floors to add privacy, and they can somewhat aid in sound transmission between floors if the stairs are contained within walls. The landing can provide a place to stop and rest when ascending, and the staircase is safer than straight stairs, as the central landing can reduce the number of treads when falling.
For stairs serving a single user (typically private residential), a minimum of 36” (91 cm) is required. In general public spaces a minimum of 44” (112 cm) must be met—providing ample space for one person and allowing the tight passage of two people. Comfortable two person stair widths range between 49” (125 cm) to 60” (152 cm). For three simultaneous users, a minimum of 74” (188 cm) is recommended. Handrails must be placed every 60” (152 cm).
