"Choose, build, play!" That's the motto of Netherlands-based company design firm qb. (FYI, we think it's pronounced "cube".) Their innovative process lets children design their own play house - choosing their own colors and patterns for everything from the exterior walls to the doorknobs - using a fun online tool. If you want a totally unique playhouse, their design team can create a custom house just for you, using a photo or image that you upload. Or you can get the basic unadorned model and have the fun of customizing it yourself.

Prices start at €499, not including delivery. To check out the customization tool, visit the qb website.
