EXP 3: PLAN AND SECTION DRAWINGS AND S/UP MODEL

My chosen plan to work with is shown below. The curved walls reflect the curving stairway 'pipes' of my bridge both in plan and section, so this was a useful plan to develop from.

Below are my plan and section drawings based from my tracing of the original plan. Whilst they are still fairly undeveloped, the exercise was useful in determining potential spaces to define to each space, and the shape of the void formed between these tubes - for example where a narrow vertical room would go and where a wide horizontal space would go. 

Below are two images showing my further developed sketchup model, in which I attempted to replicate the paths of the curved tubes in my section and plan drawings. the second image shows how the pipes act as stairways by having a path cut into them.
