> now it’s a floating McMansion! In reality it would be larger since it's used in 3D. You have 6 accessible surfaces. Most people only use their house in ~ 2 - 2.5 dimensions. Lots of other savings. Like stacking anvils on top of eggs in the cupboard and you can push things through space more optimized without the constraints of gravity. ie doors and hallways only have to be tight circles, you'll gain a lot there.
