Imagine a chance to step into your wildest childhood fantasy by spending the night in a space made entirely of LEGO. The recently opened LEGO House in the toy company’s home country of Denmark gives you just that.

Rest your head for the night in a house made out of 25 million of the world’s most ubiquitous toy bricks and turn it into your private playground. Airbnb and LEGO dreamed up this fantastic experience as a contest to give one lucky winner of any age who has been touched with a vibrant imagination to stay a night in the house. Participants must enter the competition by describing what one thing they would choose to build together with their family if they had an unlimited supply of LEGO bricks.

The winner will get a chance to create their entry with the help of host Jamie Berard, one of the world’s most prominent builders. They will also receive a one night stay in the house where they will get to sleep for the night in a LEGO bedroom under a LEGO waterfall, complete with LEGO teddy bears, lamps, alarm clocks, televisions, and even story books. They will also get to have a LEGO-inspired lunch made by robot waiters. They can tour the house’s Tree of Creativity, constructed from more than six million bricks. They will also get a chance to make their own movie, engineer robotic cars, design a city, and more while they are in the house.
