Stairs within Google SketchUp

This are my staitrs desinged on Google SketchUp.

Spiral stairs (in Moleskine bookelt its the first stair desinged). This stair is used from the top (above-ground) all the way through the ground plane to the bottom (below-ground). The materials used are wood, translucent and steel. This materials are used so that the person can see right through the stairs as they travel up and down, therefore they know how much they got to travel.

After a few hours of play with designing stairs i had came up with my own design that suited my model.

This is a closer look at the stairs that i had made myself. This stair is used from the flowers connected to the ground plane and below-ground. The material used is just plane white concrete to give the person an image that this stairs are newly made in the model.
