In Barlassina, in the province of Monza and Brianza, to reside in prestigious offices was designed this helical staircase model Etika painted in polished pink, while each tread is coated with embossed sheet steel polished non-slip. All around structural glass to create material contrast. The project was tackled with study and meticulousness, especially with regard to static calculations, with reference to horizontal torsion control cables.
