The Bildopolis Big Bilder gives kids the freedom to build their own world without rules, in a simple, fun, ecologically friendly way that challenges them to think outside the (cardboard) box.

The Bildopolis Big Bilder kit is a large-scale cardboard structure building kit designed to encourage creativity, imagination, spatial awareness, and dexterity while also teaching kids to think in 3D. Once built, the Big Bilder kit gives kids a private place to call their own while fostering imaginative play as well as providing a canvas for creative art.

The Big Bilder featured on the hit DIY Networks show "I Want That"
