How to build a treehouse

Step 12 Add an entranceway

OK, so far the build has been very conventional - all the books on treehouses will tell you how to get this far. One of my favorite bits was the following minor innovation. The two big supports poke out far past the platform, and you can use one set of these to make a slightly lower level to use as an entry. Make a small deck between the tops of the supports to about 2' out, then build diagonally back to the corner of the treehouse. Add verticals. The pictures tell the story here. I just used offcuts - with any luck you'll be able to do the same.

Some of the offcuts came from cutting the excess 2 x 10 supports off flush at the other end of the treehouse.
