This amazing wooden spiral staircase named “Riza” designed by the Norwegian architect Tron Meyer. This design rethinks a familiar architectural feature as an engineered product, it is manufactured from a single material and designed to offer a sustainable alternative to more standard designs. The designer said: “Spiral staircases today are mostly made in concrete or steel, so it was interesting for us to ask how it would work as a construction in wood, contrary to a wooden surface on a steel or concrete stair,”

The Design of the Wooden Spiral Staircase:
The designer used wood as main material for this staircase referencing Norway’s heritage of building in wood, so the product is produced from cross-laminated timber, layered and milled into precise profiles using computer-controlled machinery.

Every step in this wooden spiral staircase is formed by a combination of three layers. The lower layer in each step is craved in a concave shape to increase tread’s surface closed to the central column, so that also increases area for walking on and reduces the weight of the structure and the amount of material used. The central column gives the impression of solid cylinder due to the layered formation of the steps.

More descriptions from the designer: “We chose materials that combine strength, surface and colours that meet our standards of quality,” “To us, wood is a kind of magical material with a great variation of qualities, grown straight from the ground.”
