"Cadenza staircase"
NEST building’s STEP2 unit in Dübendorf, Switzerland,
Created by ETH Zurich and ROK Architects,
It reimagines concrete construction with 3D-printed formwork and dry-joint assembly, this helical staircase comprises 16 prefabricated steps, each connected without permanent binding materials, allowing for easy disassembly and reuse.
Reinforced with post-tensioned memory steel, the design minimizes material use while ensuring durability, embodying NEST’s commitment to sustainable and experimental building techniques.
