Also known as wall supported cantilevered stairs, the steps protrude from a side stringer. The side stringer is installed in a side wall, which is reinforced to support the staircase. This structural support should be installed before the wall is completed. The stringer can be painted and continue to be visible, but most owners prefer to have it so the wall finish runs over the stringer. This way only the steps protruding out from the wall can be seen. More simple designs may only have steel plates, but typically wood boards are added on top of the steps or completely wrapped around so the steel is not visible.
Advantages of Cantilevered Staircases:
· Very clean, modern look.
Disadvantages of Cantilevered Staircases:
· The construction and installation can be a little more expensive than other types of stairs.
