Lego House — Billund, Denmark

The $150 million LEGO House in the brand's home town of Billund opened in 2017 and is simultaneously flagship store, museum, theme park, and tribute to the brick. 21 million LEGO bricks form the building. The LEGO Tree of Creativity at the centre is a six-metre-tall sculpture built by master builders. It is the most joyful retail experience on earth.
