Cardboard Castle

Building this cardboard play castle reminded me of my mom.  Our ability to create with cardboard is completely hereditary.  

Do you think Susie would be able to create Minecraft swords without training from a cardboard master?  

Our mom created puppet show stages, giant trees, castles, and an old west town with refrigerator boxes and paint.  

When I popped open that bottle of pink tempera paint, I was flooded by memories of watching my mom create backdrops for our school plays.

For all those who don’t have paint fume flashbacks to help you out…here is a step-by-step guide for how I made the cardboard play castle for Little Miss’ princess birthday party.

Tips for making a cardboard castle

  • Make the majority of your project before the event. Then assemble the pieces in their final resting place.
  • Determine what you want to happen inside the castle. We added mirrors and jewelry so that the kids could play princess.
  • You can make your castle any color you want! We chose pink because it is my little girl’s favorite color.
Yield: 1 Castle

Cardboard Play Castle Tutorial

Cardboard Play Castle Tutorial

This castle was much easier to create than it looks.  It all started with three large boxes

Active Time 1 hour
Dry Time 3 hours
Total Time 4 hours
Difficulty Medium

Materials

Optional Items for playing in your castle

  • Fake Flowers
  • Costume Jewelry
  • Small Mirrors
  • Foam stickers 

Tools

  • Box Cutter
  • Paint Brushes
  • Something sharp to poke holes into the cardboard

Instructions

  1. Take apart all of your boxes along the seams
  2. Play around with arranging the boxes until you find a shape that you like that will stand on its own.
  3. Paint the outside of the boxes at least 2 coats of tempera paint. You may need a third coat if the print on the boxes is extra dark.
  4. To keep the box flaps upright, use hot glue to attach shims (or paint stir sticks) across the folds.
  5. Once the paint is dry, reassemble the boxes into your castle shape. If you are transporting your castle later, hold the pieces together using binder clips and or clothespins.
  6. With a sharp box cutter, cut out a door, windows, and whatever else you want to make your cardboard castle.
  7. I left the bottoms of the windows attached so that the kids could close the windows.
  8. Begin to paint the details. I used purple paint to paint the window detail and bricks around the doorway.
  9. Glue 2 pieces of the inexpensive table cloth to the inside of the doorway.
  10. Move your castle to its final destination to assemble it. Poke holes in the corners and attach the boxes together using string.
  11. Line the floor with another unfolded box. Then cover it with an inexpensive table cloth. Make sure to tape the doorway down really well.
  12. We added some glitter to parts of the castle. This is optional.
  13. "Plant" some flowers around the doorway.
  14. Decorate the inside with things that you already have. I used some foam stickers that I had from Hobby Lobby.
  15. Hang some mirrors and add some dress-up items to encourage interactive play.
