A 9-Year-Old LEGO Designer? Take a Peek at Sienna’s Winning LEGO Set

Most of us are still figuring out the instruction booklet while our kids race ahead of us — but nine-year-old Sienna took things a step further. She became one of the first children in the world to see her own idea turned into an official, worldwide LEGO set. Read on to find out how she did it, and take a peek at the set she helped design.

How Did Sienna Become a LEGO Designer?

Sienna's Winning LEGO SetLEGO ran a LEGO Friends design contest inviting children to let their imaginations run wild and create their own official LEGO set idea.

After receiving thousands of creative entries from children all over the world, LEGO chose Sienna’s design as the winning idea.

“We received creative, fun and innovative ideas for new LEGO sets from children all over the world,” said LEGO Friends designer Ricardo Silva at the time. “In the end, Sienna’s idea won because it was so appealing and original, and at the same time aesthetically pleasing with many fun design details. All the entries showed the endless creativity of children, and we are happy and humbled to find so many children interested in becoming LEGO designers.”

As the winner, Sienna and her family travelled to LEGO headquarters in Denmark, where she spent a week with the design team turning her idea into a real LEGO set. LEGO didn’t stop there — they also modelled and named a mini-doll after her, adding Sienna to the LEGO Friends gang.

Sienna’s Winning LEGO Set

Sienna's Winning LEGO SetSienna lives in London with her parents and little brother. She loves her local playground and playing with her grandmother’s dog, Pippa — and all of these favourite things found their way into her design. Her winning set, named the LEGO Friends Heartlake City Playground, is a place to have a blast with your best friends.

The 326-piece set features a tree house, a climbing wall, a slide, working swings, a spinning merry-go-round, a fountain and a rocking see-saw. Pippa the dog even makes an appearance alongside the LEGO Friends, who use their walkie-talkies to invite more friends out to play.
