Spiral stair

Spiral staircase is both functional and attractive. Spiral staircases consist of a central column, with stairs winding around it from bottom to top.

You can create a spiral staircase like this in just a minute and in that short time you can also check a few variations easily.

Structural requirements demand that the column is often made of stainless steel, however the steps and railings can be made of nearly any material, including wood, steel and glass like in this example.
