Quarter Landing Stairs, also called U-Shaped Stairs, are two parallel flights of straight stairs that are joined by a landing that creates a 180° turn in the middle of the walk line. They are similar to L-shape stairs, as both can be located in a corner. Some advantages include their ease to fit into an architectural plan, and the landing can offer a resting point partway up the stairs. They are visually more appealing than straight staircases, and they take up less linear floor space. However, Quarter Landing Stairs can be more difficult to build than simpler stair types.
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).
