Now that you’ve properly schooled yourself in the ways of acrylonitrile butadiene styrene building block-based architecture, it’s time to put those new skills to good use in an international design event that invites LEGO lovers 18 years of age or older (or juvenile Blockheads with parents/guardians over the age of 18) to construct what they imagine a sustainable city of the future might look like.

Would your sustainable LEGO city be a completely car- (or monster truck/intergalactic spacecraft) free affair? Would there be a train station, rooftop gardens, and PV arrays aplenty? Would it include a several skyscrapers clustered around an expansive green space populated by a menagerie of Duplo critters? Would SpongeBob Squarepants serve as mayor? Would Frank Lloyd Wright make an appearance? Would the whole shebang uncannily resemble an Ewok village?

Although there’s no prizes attached to Build the Change given that it's a call for designs rather than a proper design competition, entrants who post a photo or video of their LEGO eco-metropolis to the Connect4Climate Facebook page along with their name, a brief description of the design, and the hashtag #BuildTheChange (city and age are optional) might have their creations featured at the EcoCity World Summit in Nantes, France at the end of this month.

As mentioned, entrants, whether a group or an individual, must be over 18. However, of-age parents and guardians are free to share the creations of their kids on the event Facebook page. And interested parties better get building as the deadline is September 28 (submission does not guarantee that it will appear if photo/video form at the EcoCity World Summit).


On that note, those in the Nantes area are invited to participate in a giant LEGO Build the Change eco-city construction project involving a million plastic mini-bricks supplied by the Danish company. In the ballpark of 3,500 to 4,000 pint-sized builders and grade school-aged urban planners are expected to participate in the event that aims to “give children a voice in the design of the sustainable city.” C'est plus excitant!
