The main task of this exercise is to decode the logic of complex facade systems, analysing
and defining the computational process behind them. With this logic thought out students will
propose several configurations that reflect the parametrization of the building skin. This
exercise aims to train students in setting up a proper computational strategy, approaching the
complex design proposals of such facades through a series of simple steps.

Project selected – Mumbai airport (chhatrapati shivaji airport terminal 2) – Designed by som


Inspired by the form of traditional Indian pavilions, the new four-story terminal stacks a grand “headhouse,” or central processing podium, on top of highly adaptable and modular concourses below. Rather than compartmentalizing terminal functions, all concourses radiate outwards from a central processing core permitting them to swing between domestic and international service.

Just as the terminal celebrates a new global, high-tech identity for Mumbai, the structure is imbued with responses to the local setting, history, and culture. Gracious curbside drop-off zones designed for large parties of accompanying well-wishers accommodate traditional Indian arrival and departure customs. Regional patterns and textures are subtly integrated into the terminal’s architecture at all scales. From the articulated coffered treatment on the headhouse columns and roof surfaces to the intricate jali window screens that filter dappled light into the concourses, Terminal 2 demonstrates the potential for a modern airport to view tradition anew. – courtesy of som

Varying iteration were created by increasing the diameter of the form parametrically from which volted dome structure can be created.

Sudo code used for creating the grasshopper definition.

  1. Create a point at 0,0,0
  2. Use point to create a square base and move/copy in z axis
  3. Scale the moved/copied geometry using the center
  4. Loft the geometry and deconstruct
  5. Use the faces to create diamond panels
  6. Cull the list to separate the solid, diamond and sphere insets
  7. Deconstruct and find the center of each segment to interpolate
  8. Find the normal to move the geometry
  9. Use the plane attracter to control the opening and move heights
  10. Loft the move/copied geometry with the existing curves
  11. Cull the triangulated geometry
  12. Cull by area to segregate the needed faces
  13. Perform inset and move using the same attractor above
  14. Merge the needed geometry and bake!
