Why is the central hole square? Wouldn’t the orientation of the square hole have to change with each step, requiring dozens of unique steps to cut out? Whereas a round central shaft would enable you to make only the 4 basic outlines of steps because each could be rotated to any position on the supporting shaft?

In the center there is a supporting brick column, it has a square cross section. The customer had a desire to make steps around the square to strengthen the staircase structure.

Very nice @Antey85 👏  
Check out ‘Grand Designs’ on Channel 4 (UK). There was an architect that did something very similar to this - end result looked really good.  
I’d also add in a part number to the CNC - thats one big puzzle! 😆
