Thanks for the answer. The schetch I linked was just a scetch. The number of steps are most likely compleatly wrong. I'm just after the "shape" of the staircase. I would say that the staircase is 2.55m high and ruffly two meters in length.

I'm a simple programmer not a designer so to give it a go in by my self in a 3D modeling program is out of the question

If some kind soul would like to help me out I would be more than willing to give the exact dimentions.

I'll post a more acurate schetch tonight
