This is a well-known staircase of University of Technology Sydney in Sydney Australia. The double ribbon spiral design is inspired by the double helix structure of a DNA molecule. It is not only an impressive design feature, but also a reminder of how breakthroughs in science and technology have transformed our world. The double helix is one of three ‘architectural’ stairways in the building, which link the main student spaces in the lower floors of the building, inviting movement and connection, and reducing reliance on the lifts and escalators.
