I use a hand truck to move around the 2Pi Towers that I build. I used the hand truck even in the later stages of construction and after moving them around to different rooms. You just need to take a bit of care so you don't scratch or ding the wood or finish.
I hope you have one (hand truck), if not they can be obtained at the hardware warehouse store for about $30.00 and you will find other uses for it in the future.
