This modern staircase was made from a 10mm thick metal sheet. Each of the adjoining steps is connected with a slanting external side beam that forms a bracket attached to the wall. With a concept of a delicate rippling ribbon is definitely one of the most unique and thinnest staircases ever seen. It was created by HSH and it is now in one the contemporary houses in Liben, Prague. Although this original piece might look fragile, each of its brackets is constructed as a firm frame, so it is sturdy enough to carry weights.

6. Staircase at XXS House

What is so special about this staircase? Well, the design required remarkably little material and still functions as a regular set of stairs. It was created by Architect Dekleva Gregoric's for an eXtra-eXtra-Small house located in a little historic town in Slovenia. Its dimensions were dictated by law to fall within the measurements of the preexisting house on the site, leaving just 43m-sq (approx 460ft-sq) of potential space. If good things come in small packages, then the XXS house is as good as it gets!

12. Foldable Staircase



This originality was thought not only as a foldable staircase but as a ‘redefined door'. According to its creator, industrial designer Aaron Tang, it is “an element of a wall that allowed passageway to another environment when opened and restricted passageway when closed”. Using just hinges and pistons, the staircase can fold up a wall to expand space on the lower level or restrict access to the upper level. It was designed to be closed or opened from upstairs and downstairs.
