Diverging glass staircase by Nico van der Meulen Architects
You approach this staircase on a glass walkway over a koi-pond.
The staircase is suspended over the open part of the koi-pond without any vertical support in the water, to enable a pool cleaner to be used under it.
The treads are backlit with LED striplights.
The staircase diverges on the landing and becomes a double staircase from that point.
