This is a residential building complex located in Darmstadt, Germany. The building has a unique façade which doesn’t follow a regular grid pattern and the windows appear as if they are dancing out of line and appear out of order.  It was designed by Viennese artist Friedensreich Hundertwasser and finally planned and implemented by architect Heinz M. Springmann. It contains 105 apartments, an inner courtyard, a small artificial lake and also a playground for children. The building has 12 floors.
