So we're giving the
LostRiverModern treehouse a dry run here in our full-time backyard:

We're working with three trees as our supports, which lends itself nicely to a modern shape, and to a fun triangular pitched roof.

Hard to keep kids off as you build...

Probably a little overbuilt, and it'll be a pain to take apart if our landlord makes us dismantle it before we move on to greener pastures.

The floor is 7/8" BC board (sometimes called project board), which has a nice smooth finish and is plenty sturdy. Most of my power tools are out in WV (including my jig saw), which meant some tricky and not-recommended improvisation with an old skil saw to shape the floor around the trees...

The plan is to use 1x2 slats in a rain-screen application for the walls, and to screen it in (mosquitoes are tough in these parts). About $350 in lumber and misc. materials. I fastened the beams with 1/2 x 6" lag screws. Not much to it after that. Framed the floor, roof and ladder; the roof will be corrugated plastic. Should finish today or tomorrow...
Michael says it's "awesome."
