Stair of the Week: DNA Stair from Studio P-H-A : TreeHugger

The stairs are stainless steel, water-jet cut from sheets, and hung from stainless steel rods , which act also as the guards. Landings are glass. “We desired to give a ‘technological’ impression to the entire structure, which would correspond with the exactness of a scientific institution,” Sesták says. To invoke the correspondence more literally, the glass landings are printed with an antislip grid in a pattern derived from DNA-sequence-registration-machine outputs.”
