yes me too, i can use ladders but try and do a spiral staircase...no chance

have you seen the second image?
* first you place pillars that will be hidden inside the big pillar ether one at a time or all 4 at once.
* then you can place stairs to the desired height, may need rotate both stair and camera to place where you want it
* Optional you may add platform ledge at the top with pillar top can also be used standalone to any pillar
