What is LEGO® Build Day?

On LEGO® Build Day, people across the world gather their spare LEGO bricks and build – well, anything! It works like this: You build something unique. Then you share it with the world by tagging it with #LEGOBuildDay. That’s it!

When is LEGO Build Day?

This year (2023), LEGO Build Day is set for December 27th.

What should I build for LEGO Build Day?

“Should”? That’s a bad word around here! You decide what you build. Big, small, simple or wildly complicated, we love it all. You can build an extension to a current set you own, or unbuild and rebuild it into something completely different. Take a spaceship and rebuild it into a panda bear hammock. When it comes to creativity, let’s face it – you’re the expert!

How can I get involved in LEGO Build Day?

Build something with your spare LEGO bricks, and share it on the social media platform of your choice. Remember to tag it with #LEGOBuildDay so the whole world can see it!
