Bridge model - first draft

Based on one of the sketches I made in class last week, I created this on SketchUp. The model is a clear/transparent seeming space because I envision it to be made out of glass. The hollow spaces are walking spaces, and the closed areas are rooms.

I then decided to add a space in the model where stairs could be placed, to take you from the bridge on the ground floor to the bridges on the second floor. I created four of these spaces, on both the left and right side of the model, and on both the front and the back of the model. This is shown in the images below.
