Betonhausen is A D.I.Y. spot in Berlin funded by c-list energy drink. (But really, is there anything as an grade A energy drink?) It has an outdoor part that looks like it served as the concrete college. Check it out. They’ve added an indoor part as well, 3 videos after the jump. The best video in the series is part two, which features the construction, including huge chunks of styrofoam sculpted in place and used instead of fill dirt.
