This appartment house designed by painter Friedensreich Hundertwasser was completed in 1985, and it has become a major Viennese tourist attraction ever since. It surely sticks out from all the other community housing buildings in Vienna, but whether or not this is architecture is something that at least should be discussed (I have my doubts). It looks quite nice in spring and summer when all the trees have green leaves, but it looks more like a haunted house in winter (especially in the evening, when this shot was taken).
