Brynjar Karl Birgisson, a teenager from Reykjavík who is on the autism spectrum, transformed a childhood obsession with ships and plastic bricks into the world’s largest LEGO model of the Titanic, using a staggering 65 thousand pieces.

His journey started in 2013, when 11-year-old Brynjar laid out the ship’s blueprints on his bedroom floor and vowed to recreate them at LEGO scale. Eleven months and roughly 700 hours later, the five-foot-tall, 24-foot-long vessel stood finished—though only after a bow collapse forced him to add nearly 9 thousand extra bricks to the original 56 thousand-piece plan.

Precision mattered. With help from his grandfather, a retired engineer, Brynjar converted the real Titanic’s measurements so every LEGO minifigure would stand in proper proportion to the decks and funnels—a feat of math as much as patience. His mother handled crowdfunding, warehouse space, and the media requests that began pouring in even before the last brick clicked into place.

The colossal model soon went on tour, stopping at museums in Norway, Sweden, and Germany before anchoring in 2019 at the Titanic Museum Attraction in Pigeon Forge, Tennessee, where it drew crowds through the end of 2020. The exposure earned Brynjar the nickname “the LEGO Boy” and spurred invitations to deliver a TED Talk and publish his memoir My Autistic X Factor, in which he urges young people to embrace their special interests as superpowers rather than obstacles.

Now in his twenties, Brynjar keeps building—and dreaming bigger. In 2022 he unveiled a LEGO Boeing 737 in Copenhagen and announced a documentary, How the Titanic Became My Lifeboat, hoping his story will encourage schools and workplaces to make room for different kinds of minds.

What began as a boy’s quest to honor a historic ship has become a floating classroom on neurodiversity: proof that when passion meets support, even 65 thousand tiny bricks can shape a life-size message of inclusion.
