The spiral staircase design with a gilded fantasy fencing and opened marble steps is an actual interpretation of the classic style. It forms a spectacular vertical, distinguishing the layout of the hall, and is a stylish interior dominant. Due to the absence of risers and the illumination of the base, the construction looks light and openwork, and therefore does not pile up the space at all, and the light shade of marble made it possible to fit it into the atmosphere as organically as possible. The significance of this large-scale element is emphasized by the floor pattern, and the shape of the stairs – by the original ring stained-glass window on the ceiling, supplemented by LED-illumination and stucco decoration.
