The Crystal Laboratory     Developed in a model building workshop for the Familienservice’s new school, the children’s imaginary worlds were full of plush and comfortable sleeping areas containing various jewels of delight. Alternately, the children also imagined worlds full of ice crystals and ice bombs – a place so cold and icy, that nobody would dare set foot inside. As a result, the core areas (spacious hallways) of the fifth floor of an office building located in the Lützowstraße were converted into a Crystal Laboratory, with a Heat Lab for the planned kitchen area and a Coldness Research Lab next door. From the labs, crystals grow as single modules into the class rooms. They can be used either as separation walls or toys which the children can inhabit, decorate, or climb through.
