Spiral wine cellars

Anything that offers extra storage space in a space where it was previously thought impossible will always get a hearty cheer from me. Living in a tiny space makes you appreciate the finer things in life. So these Spiral Wine Cellars, which are essentially wells sunk into the floor and filled with a staircase surrounded by up to 1900 wine bottles are something I'm seriously considering. They could also be used to store irritating relatives for a while - simply ask them to fetch a bottle and "accidentally" shut the trap door for half and hour or so. Or is that going a bit too far?
