Lego is having a sleepover at its newly-opened Lego House in Denmark.

The Danish toy company has teamed up with Airbnb to allow one family to stay the night at its new attraction - a 12,000 sq m (129,167 sq ft) building filled with 25 million of its plastic bricks.

There's a parents' bedroom that features a Lego cat, slippers, a coffee pot and even a newspaper made from the bricks.

In the children's bedroom there's a Lego teddy bear, lamp and story book. Towering above the child's bed is a six-metre (20-ft) brick waterfall, surrounded by a seemingly bottomless pool of Lego bricks.

Those who want to join Lego's private sleepover must enter a competition and describe what they would build if they had an infinite supply of Lego bricks.

"What I do as a as a job is I actually make the products that you can buy at the toy stores," says Lego design manager Jamie Berard.

"So, to do something like this outrageous waterfall or to recreate a bedroom out of what is currently not really a living space is a wonderful challenge."

The winner will get the chance to create their entry under expert supervision, as part of their stay.

Designed by Danish architect Bjarke Ingels, Lego House opened in late September after four years building work.

The attraction is located in central Billund, a small town in Danish Jutland where the toy company has its headquarters.

Towering at the building's centre is a 15m Lego brick tree, named the Tree of Creativity, which took over 24,000 working hours to construct.

Made from over six million bricks, it charts the gradual evolution of the toy company's creations.

The competition launches on Thursday and is to run till mid-November. The winner's family will visit the Lego House on November 24.

This is not Airbnb's first sleepover contest - last year, it invited people to spend a night next to the shark tank at Paris Aquarium and at "Dracula's castle" in Romania.

It was the first time Bran Castle had welcomed overnight guests since 1948.

The Lego experience is rather tame by comparison, unless barefoot visitors should unwittingly step on a stray Lego brick.

Adults are advised to wear Lego-proof slippers just to be safe.

"I wish I was the one that could just sleep in here," says seven-year-old Albert Landbo, who was visiting with his brother Gustav and their parents.

Asked what creation he proposed for the competition, he said: "I think I would make a little baby husky."
