In this idea project, the concept was to explore the formation of a geometric ‘growth’ as resultant of systematic development of a structural shell/canopy spanning a railway platform of about 100’ x300’. The approach was juxtaposed with an innovative structural intervention. Aesthetic, force and forms of the canopy were generated carefully in pure geometry and symmetrical order. The result was a thin structure sitting on the platform like a tree canopy and merging with the surrounding.

Floor Plans And Elevation

The structural idea was to create an elevated skeleton to express the floating sense of feeling. It was executed using tubular steels columns of 10” diameter as the primary structure and 6” tubular columns on the secondary structural membrane. The geometric approach included a hexagonal tube on the center to distribute the load evenly.

The shell is proposed to be double-layered PTFE( Ethylene tetrafluoroethylene) to resist heat and allow cool daylight. Hence transparency to achieve floating feel again. PTFE layers would be attached using tertiary solid steel tubes with the secondary members. Plan
