In order to make my staircase I’d started with a 2 storey block. After dragging the flooring to the size and shape you want, simply delete the block and you’re left with a floating foundation. To make a build float you first need to build a 1, 2 or 3 storey block, upon which you place a piece of flooring. Unfortunately, once I’d started building I realised this wasn’t going to work. I had visions of a spiralling staircase leading up to an imposing and grand castle and I wanted nothing more than for that to be my end product.
The thing that really makes this build fantastical is the fact that it floats so it was essential that this element was perfect.
