For the hardcore LEGO-loving families out there, this one's for you. Airbnb and LEGO are currently running a global contest asking one question: In a response of 50-500 characters, “If you and your family had an infinite supply of LEGO bricks, what would you build?” 

The grand prize? The winner and their family (or up to three guests) will be flown out to the new LEGO House in Billund, Denmark for a free one-night stay from November 24-25, 2017. 

The winning guests will embark on an interactive journey through the LEGO House, which Bjarke Ingels designed. The host, LEGO Master Builder Jamie, will lead a tour of the building — including the Tree of Creativity, the Masterpiece Gallery, and the interactive Experience Zones where you can create your own LEGO films, robotic cars, and more. 

The final stop is a bedroom “floating” in a pool of bricks underneath a 6-meter-tall LEGO “waterfall”, with furniture completely made of LEGO bricks. Before calling it a day, the winner and their family can work together with Jamie to build a real-life version of their winning entry using the endless supply of LEGO bricks — so be prepared for a little physical activity.

The following morning after breakfast and before doors reopen to the public, the winning guests will get to leave with one last surprise from the LEGO House: “We won’t reveal it here, but let’s just say that in some small way, your family will leave your footprint in LEGO House long after you leave, just like the memories of your time here.”

Submit your LEGO “dream creation” now until November 16, 2017 at 11:59 p.m. Pacific Time. For full contest details and rules, visit Airbnb.
