The sculptural floating stair is an example of excellence in steel design, engineering, and construction while dealing with the constraints of an existing building and the demands of a live fit-out project. The main design feature of the project involved the design and documentation
of a self-supporting, helical structural steel stair spanning the height of two equivalent storeys
and then separated into two independent flights at the upper transition. The stair was wrapped in lathed timber battens, finished with marble treads. Partridge were honoured to receive the ACSE Award for Excellence in Structural Engineering – Unusual Projects.
