King’s Cross pedestrian tunnel in London features a tiled floor of interlocking triangles, set along a sloping curve. The conceptual design of the floor complements the other key elements: the canopy, the fin section and the integrated art-wall of LED lights. Craven Dunnill successfully solved the geometric and mathematical challenges created by the irregular floor, providing the required technical CAD expertise and supplying the water-jet cut tiles to an accuracy of 0.1mm.
