Hyperion
This large four flight helical staircase in a central London office has a complex geometry due being elliptical on plan with unsupported mid-landings that fall in different places on each flight. The steel frame was clad in GRG plaster and finished with a metallic paint. There is also an inset LED track to the recessed handrail.
Project number: SS964
