Sketchup Models of Stairs

Here are Sketchup Models of the aformentioned stairs.

These are stairs to link the above and below spaces with the ground level exhibition space for the Australian-Evolution building.

The below stairs are formed from domed cylinders with flat tops. The elongated domes suggest the lower space are of an organic nature, emerging from the depths of the earth and time emphasized by the granite material. The flat top allows for the user to actually step on them, whilst the sandstone paving visually links the below ground to the above ground which is described as Australian.

The Upper stairs are large blocks of sandstone, a classic Australian signature, in alternating steps of glass disks, which symbolise the scientific ground on which evolution is based. The circular disks are arranged in helix formation to further suggest this point. Despite the physical improbability of this being constructed, these stairs provide a link between the Australian and Evolution levels of the building.
