Okay I tried this on a whim, And I was right! All you have to do is place several columns in the shape of the house you want to build then fill it in just enough to where you can place a whole floor on top of them then just put down your floors add walls and put stairs on the outside of your house you can make a porch or w-e you want as this is the only way into the house. After you finish the house and are happy with the results just delete all the columns you placed and your house will just sit there floating in the air! This glitch can also be used to make any sized second story balcony you want as well.
