I don't drink wine, I don't have a cellar — or even dirt under my flat to install a cellar in — but man, this is one freakishly desirable batcave/staircase thinggum.
Ever want a wine cellar but don't have the space or money to build one? The Spiral Cellars design/build firm will dig a hole right in whatever room you want your cellar in and haul the dirt right out the front door. In the remaining void they infill a highly functionally and visually dazzling spiral-staircase wine cellar to fit all your favorite vintages and go with your favorite funky furniture designs.
Wonderful Wine Cellars For Any Room in Your House
