Did you know Toronto's CN Tower has the tallest metal staircase in the world? Inside, the tower contains 2,579 steps, and, interestingly, a massive wine cellar at the top that can hold up to 9,000 bottles. Funnily enough, staircases and cellars make great places to stash things around your house - until they just start getting in the way, that is. Stop using your steps as a makeshift bookcase and turn your basement into an amazing mancave or she-shed. Start the home makeover with the perfect self-storage unit for all that stuff! Problem Solved.
