This structure is an 8'x8' platform supported on posts. It can be used to support the Kauri, San Pedro, and Zelkova treehouses if you have no suitable trees (plans available separately). You can also use this plan as a base for your own treehouse design, provided it is 8'x8' or less and of similar general style to the treehouses listed above. The platform has options to be built using partial tree support, with two layouts using tree supports included in the guide.

The guide covers every step of the build with diagrams to illustrate the location of parts and position of bolts. There are no complicated techniques to learn, no difficult joints to master, and all the materials are readily available. A marginless version of the guide is included for ereaders. Help is available by email and a 28 day satisfaction guarantee applies.

This guide is included free if you buy the San Pedro, Kauri, and Zelkova treehouses, and is specifically designed to convert them to full post support.

Site options and requirements

Your treehouse can be built entirely on posts or with one tree plus posts, and custom instructions are included for these different methods. The site requirements vary depending on the design you use for your site:

• Four posts: level ground which is not subject to flooding and has a low proportion of sand
• Three posts and one tree: level ground as above, plus a healthy tree of at least 9" diameter at floor level
• Two posts and one tree: level ground as above, plus a healthy tree of at least 12" diameter at floor level
