Rest landing stairs
A resting plane staircase can have a different shape depending on the design of the resting plane.
The most common is to have a corner landing (L-shaped) or a landing in the full width of the stairs (U-shaped as in the picture) and two straight flights of stairs that meet the landing. Both side-rail stairs and stairs with an underlying rail can be obtained in a resting plane design. Often, the resting plane itself may need an extra, supporting post for the floor to become stable.
