ASSEMBLY DIAGRAM FOR DOUBLE SKIN SYSTEM

Points are strategically pushed and pulled to create an S-shaped base and a curved section which promotes structural

balance of the system. The triangles are subdivided and transformed into pentagonal cells for rigidity.

ASSEMBLY PROCESS: An Adjustable Triangle Acts As An “Adjustable Jig� For Creating All The Unique Bends In The 18 Cell Wall System

Maintaining coplanar geometry in nontriangulated surfaces is one of the many challenges modelling

Triangulated faces are a common solution to achieving co-planarity, however this limits the patterns and forms that can be developed. The major innovation in this project is the subdivision of giant triangular planes into three pentagons.

Each

pentagonal cell has a unique bent flap detail which allows for easy and adjustable edge-to-edge connections.
