Take the construction fun outdoors and build your own play space with our Colorblock Build-A-Fort Building Kit! Designed with the same concept as our customer-favorite indoor cardboard Fantasy Fort sets, but made of lightweight corrugated plastic (rather than cardboard) for outdoor building, these brightly colored panels will stand out in your backyard, beckoning friends and neighbors to come join the building fun. Set includes 12 solid panels and four window panels in four bold colors. Connect with included carton-building clips and a roll of hook & loop tape. When construction play is complete, design a storage box using panels. Extend the life of this fort-building kit by storing the pieces indoors when building fun is complete. Building with our Build-A-Fort kits allows for open-ended creative construction-the possibilities for forts and play spaces are endless! Combine sets and build more!
