The Stair

1. Spiral

These are my drawings at the beginning of figuring out the design of this staircase, I am trying to experiment with direction, railing and line of the stairs section.

The left page is a section showing the direction the two staircases go when they cross over the others path. One spins around the inside and the other spins around the outside.
On the right page is a section of the stairs that are shown below, the irregular shapes move around and connect together to create this staircase.

These are my product of my first page design and messy sketches

2. Wave

First part of concept on bottom right

I took the inspiration of the stair that moves in the direction of a wave as it slopes up.
These are a few different sections on the design.  

Sketch up model of stair in this style.

3. Rigid

This design is similar to the one above.

Rigid stair case, where the steps are placed in an irregular pattern, this making it look like rocks rather than neat stairs.

Each step is different sizes but all the same shape of a simple square block.

I think these stairs would be impossible to walk on, however they do have a sculptural effect

4. Skeleton 

The top sketch (right page) are my beginning rough sketches of this idea.

The intention is to have low risers and long treads for an easy and slow ascend and descend.

My aim was to have tick frames of the same size step and then have them overlap each other to show geometric shapes, with the centers being clear, so can see the 'skeleton' of the stairs.
