It took a few seconds for my brain to work these stairs out!
Designed by Diapo.
The muse for this staircase is a recent installation by Do Ho Suh at the Tate Modern Gallery called “Staircase-III”. Staircase-III is a short flight of 12 steps that start in mid air and finish at the ceiling of the Tate Gallery. Meant only to be sculptural and not functional, the flight of stairs is created with a see through gauzy balustrade and a thin run of continuous steps.
