This unique and quirky upside-down house in Germany was created by two talented Polish designers as a part of the “The World Upside Down” project. Every piece of furniture is upside-down and, though the house is big enough to be lived in (it even has a bathroom), you can’t obviously live there. The house is situated in the town of Trassenheide on Germany’s Baltic Sea island of Usedom and is open as a tourist attraction.
