A cardboard castle for a princess party. I crawled through myself easily and im 5″10. These boxes are approx 50×60.
I bought 30 for $30 by replying to a gumtree ad


  • 23 boxes Cardboard boxes approx 50x60
  • 2 rolls Packing tape
  • 1 Stanley knife


  1. Arrange boxes into tower 3 high by closing the bottom flaps of one box and stacking 2 opened boxes inside so the tower is open for a child to stand inside of. Fo this 4 times for the corner towers
  2. Slide boxes inside of each other with open flaps so they join into a tunnel. Do this 3 times then join them with sticky tape to the sides of the towers.
  3. Cut doors on the tower entrances. Cut windows.
    Crawl through and make sure no flaps are hanging down.


I made this for my daughters 4th birthday party. My partner and myself only spent about 2 hours total. So easy and everyone loved it
