Redesign- Sundial Project: 

Redesign- Sundial Project Original Concept The Sundial will be a marker of time and movement of the activities that occur inside the building Hallways acting like a Telescope (provide view to SF), allowing outsiders to have a clear view of the activities occurring inside. Goal Add Cafeteria and Gym Using the unique cone structure to centralize main social activity Provide more efficient circulation and encourage interaction.

Floor Plan :

Attempt of Material Choice: 

Attempt of Material Choice A: Using Tensile structure for the cone structure E: Concern about safety Issues: Wind velocity Owner : Low R-Value for the tensile structure Use double glazing for the structure A: short life cycle of the structural material
