Redesign- Sundial Project

Original ConceptThe 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.GoalAdd Cafeteria and GymUsing the unique cone structure to centralize main social activity Provide more efficient circulation and encourage interaction.

Floor Plan Gym 2 Floor height open space 660 SF- 26 400 SF - 16

Attempt of Material ChoiceA: Using Tensile structure for the cone structureE: Concern about safety Issues: Wind velocityOwner : Low R-Value for the tensile structureUse double glazing for the structure A: short life cycle of the structural material

Comments

+ s- s- Strong sense of directionality- Clear frame and core defined- Repetition, Symmetry Scarify large amount of space Complex interactions between systems- Too Expensive Simple Form and Clear Circulation path Various informal social space Two Uniformed structure system- Challenging Design- Exceeding height limit The form is too Rigid Eccentric moment issue- Amount of Glass Strong Form and Gesture Provide multi level special experiences Simple gravity system Reassembly of materials\ Lack of informal social space- Non-Uninformed Long beams Complicated concrete
