The 13-Storey Treehouse

The 13-Storey Treehouse (known in the US as The 13-Story Treehouse) is a 2011 book written by author Andy Griffiths and illustrated by Terry Denton, and a stage play based on the book. The story follows Andy and Terry, who are living in a 13-storey treehouse, struggling to finish their book on time among many distractions and their friend Jill, who lives in a house full of animals and often visits them. According to the book, the 13-storey treehouse has: "A bowling alley, a see-through swimming pool, a tank full of man-eating sharks, vines you can swing on, a games room, a secret underground laboratory, a lemonade fountain, a vegetable vaporiser, a marshmallow machine that follows you around and automatically shoots marshmallows into your mouth whenever you're hungry, an observation deck, a giant catapult, a room full of pillows and a library and theatre room”.

The 13-Storey Treehouse won the Australian Book Industry Awards Book of the Year for Older Children 2012 and the 2012 COOL Award for Fiction for Older Readers.
