6. 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.
