11. Eureka Car Park
Location: Melbourne, Australia
One way to brighten up the spooky atmosphere of a parking garage is to open it up with more glass, mesh, and space. If you can't do that, primary colors tend to do the trick, as well, which was part of the focus at the Eureka Car Park. Designer Axel Peemoeller color-coded the entire garage with nifty optically illusional words on the walls that lead you where you want to go. Red will take you to an exit, Green leads in intot he garage, blue goes up, and yellow goes down.
