White Stairway. Architectural marvel!

A spiral staircase made of concrete rises through the centre of an open-plan office designed by architecture studio Hildebrand in Steinhausen, Switzerland.

Winding its way up the building’s four levels, the staircase ends with a large elliptical skylight that brings light into the centre of each floor.
