St Helens Needle

Posted on Posted in Science

The brief was to design a feature element and stair that would link an existing roof top car park to the new arts quarter of St Helens. The staircase is a full 360degree helix with no supporting columns. A 600mm diameter torsion tube that sits under the stair provides the stiffness. The spire is a 20m-polished stainless steel tube with a series of drilled holes to let light shine out from the top.
