Project Abstract
The programming of the definition for these adaptive stairs serves the purpose of investigating parametric design as a type of procedural
modelling by using Rhino Grasshopper comprising of parameters, algorithms and their outcomes. The Grasshopper definition uses an extensive set of parameters, published to Rhino’s remote control panel to adapt the design in real-time. The design of the stairs aims to recreate the stairs at the BEEAH Headquarters by Zaha Hadid Architects.
Digital tools used
Rhino 3d, Grasshopper, V-ray.

Once the algorithm is set, it enables the designer to operate the design dynamically for the purpose of exploration and rapid versioning.
