Take the construction fun outdoors and build your own play space with HearthSong's 16-Piece Mighty Fantasy Forts™ Colorblock Build-A-Fort™ Kit! Designed with the same concept as the customer-favorite indoor cardboard fort-building 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 the included carton-building clips and a roll of hook & loop tape. Bonus – you can even design a storage box using five panels. Extend the life of this fort-building kit by storing the pieces indoors when building fun is complete.

Building with this Build-A-Fort™ Kit allows for open-ended creative construction—the possibilities for forts and play spaces are endless! Combine sets and build more!


  • Build your own indoor or outdoor play space with the Mighty Fantasy Forts™ 16-Piece Colorblock Build-A-Fort™ Kit – open-ended, creative construction with endless possibilities!
  • Durable 22-inch-square, lightweight, corrugated plastic panels can be connected on any of their four sides with the innovative double-sided hook & loop connectors (easy to fasten and unfasten).
  • Comes with everything you need to build a fantasy fort: 16 colorful panels (12 solid panels and 4 window panels) in four bold colors (orange, purple, red and teal), carton building clips to support two stories, and double-sided hook & loop connectors.
  • Inspire kids to ditch the screens and engage in imaginative play by building, pretending, and dreaming inside their fort! While several kids can build at once, this kit is also perfect for independent play.
  • Made for indoors or outdoors, but store indoors when not in use.
  • Combine sets and build more!
