This is a suggested design for a helical stair that curves around a lift shaft, it’s distinguished by having no outer stringer or traditional brackets to support the treads. This is achieved by using Spiral’s G-fin glass riser system which gives the stair structural integrity by  using the glass and aluminium risers as  beams cantilevered from the centre string.
