Folio Staircase by Disguincio & Co
Italian studio Disguincio & Co has produced a concept for a spiral staircase with steps made from folds of fibreglass.

The Folio Staircase by Pordenone-based practice Disguincio & Co would comprise a repeated sequence of steps that slot into each other to make a spiral staircase.

Each step is flexible and relatively weak, but when pieced together the whole staircase would become stable and robust, says designer Mirk Daneluzzo.

The steps would be made from fibreglass reinforced with carbon fibre strips, although Daneluzzo hopes to utilise other materials in the future. "We are actually doing research to select environmentally sustainable solutions to have a natural fibre and bio-polymer-matrix composite," he told Dezeen.

For the moment there is no working prototype of the staircase, only a small model. "We are working to make it as soon as possible, in collaboration with some producers," added Daneluzzo.

We recently featured another concept for a spiral staircase using a single repeated element, this time based on a whale's backbone.

Other staircases we've published lately include flights of stairs floating in mid-air by artists Lang/Baumann and a ladder-like wireframe staircase leading to a mezzanine bedroom – see all staircases.
