I spent two days at my grandparents house in Karlsruhe (not the house in the picture!).
And as I was walking through the shopping streets of Karlsruhe I suddenly found this house hanging around.
I think it's art because last time I've been in KA the house has already been there. I don't really get the meaning of this to be honest. Maybe it's kind of a protest against the huge building work going on in KA these days regarding the underground train. Maybe not. :D
