Not your typical spiral staircase, this organic form is a concept by artist and architect Andrew McConnell. The piece, entitled the Vertebrae Staircase, is based off of the spine of a whale. According to the artist's website, the project "is not simply mimicry of organic form but an exploration in shaping structure. Much of the design work went into refining the single component, or vertebra, that mate with each other creating a unified spine running from floor plate to floor plate."
The idea involves several components, including an outer, layered surface of durable composite fiber material; steel fittings and pins that lock the vertebrae together; and a handrail and steps that are reinforced by structural foam and a network of steel rods. The single flowing concept is anchored by two steel plates at the base and the top, and is meant to function as a self-supporting staircase. The futuristic plan is a visually appealing concept that also serves as a constant and unique reminder of the enduring forms of nature.
