Airbnb and Lego House unveil the most fantastic nocturnal experience ever organized. For one entire night the Lego House recently opened in Billund, Denmark will become a private playground for an entire family.

To be able to win a night in Lego House aspiring master builders of all ages have to use their imagination to describe a project they want to complete with their family, using a virtually infinite supply of Lego bricks.

The winners can enjoy a stay at Lego House for one night, sleeping in a Lego bed and creating their project with the help of the host Jamie Berard, one of the best master builders in the world.
