What makes a neighbourhood feel alive? For the Open House Dublin 2026 LEGO® Brick Building Competition, we’re inviting young builders to imagine, design and create their own vision of a living neighbourhood. Using LEGO® bricks, build a place, building, street or neighbourhood that brings people together, supports community and is a place you would want to live in. Think about the spaces we share, the places we care for and the ideas that could make our neighbourhoods thrive and then bring your vision to life, one brick at a time.

The competition is open to children aged 4-17. The closing date for entries is 1 November 2026.

The competition will be judged by LEGO® Brick Artist Jessica Farrell.
