The adjustable staircase comprises a plurality of treads T fixable at a plurality of different angles between a pair of stringers. Fixing holes may be provided in the stringers and in both ends of each tread. When respective holes in a stringer and tread are aligned, a bolt can be passed through the holes and fastened with a nut to fix the tread to the stringer. This enables a fixing angle to be selected such that the treads are substantially horizontal, independently of the slope of the stringers. A foot piece FP may be fixable at a plurality of positions along the lower end of each stringer, the length from a top end of each stringer to a ground engaging portion of each foot piece being adjustable. Each stringer may be constructed from multiple stringer plates SP5, SP6 joined by joining plates JP. Each foot piece may define a specific or variable angle of rise for each stringer. The staircase may be dismantleable and reconstructable. Also claimed is a kit comprising stringer plates, joining pieces for assembling the stringer plates into a pair of stringers, foot pieces, treads, and a landing catch plate LCP.
