Rising eight metres above Denman Prospect, Everchange by Benjamin Shine is brought to life by thousands of wind-driven spinners, and a carefully engineered structural system behind the scenes. Partridge designed the steel sphere and quadripod leg frame that support the sculpture’s weight, movement, and environmental loads. Using detailed modelling and hand calculations, we refined the frame to limit sway and ensure long-term stability. We also collaborated with TILT on internal cable bracing, transport frames, and installation planning. The result is a dynamic, kinetic artwork underpinned by precise structural engineering and a commitment to making ambitious public art possible.
