Perfectly inserted in a superb chalet in Haute-Savoie, this sculptural spiral staircase on two levels connects living area -living room with private bar and wine bar- and sleeping area. The staircase rests on a floral Bisazza and creates a wonderful contrast with the ceiling of antique larch wood: of metal painted in the spot of micaceous rose, has maintained for style choice the visible porosity; with stiffness on the central pole, curved elements help to create an organic shape; the terminal is shaped to design a flame-domed, the start is with curved handrail radiated, the landing step on the first floor consists of open glass tray.
