Valuable original building blocks have been recreated in various materials so that we can play and build with them together on a large scale at the MAK. We invite you to a fun architecture competition featuring historical building systems, supplemented by Bioblo and, of course, LEGO. Your creations will be judged by the friendliest jury in Vienna—yourselves! You can experiment to see which bricks work best for building, playing, and storytelling—whatever you like, however you like it!
