Treehouse - Part 2

So here's an update. Dave framed the treehouse with 2 x 3s. Lighter and cheaper than 2 x 4s, but certainly strong enough for a structure this size. So far, it's going pretty smoothly. Note the little helper below. He's pretty much there with his dad for the whole process, so Dave is keeping power tools to a minimum. Next up? Roof and siding.
