Cantilevered stairs, or floating stairs, are a type of staircase.
A metal safety rail has been added to the outside of this cantilevered stone staircase.
A cantilever is a beam, which is anchored at only one end. Thus cantilevered stairs have a "floating" appearance, and they may be composed of different materials, such as wood, glass, stone, or stainless steel.[1]
