Getting a bit closer to the the finished product. These are two sections through my Jumble/Golden developed sketchup model. As you can see, I have completely redesigned my below ground level after a consultation with the tutor. I have gone for a much simpler shape down below that better represents the concept of 'golden' i.e a radiation and projection all around. To this end I have placed the spiral staircase in the exact center of the room to give the effect of the walls receding away from the user when they descend the staircase.
