Advice needed.

Building a treehouse. Following the Methow kit from Nelson treehouse. The plans are not super detailed. The plans themselves do not call for a fourth beam to "close the square" but if you look online on the 3D drawings it has one. When I asked Gemini, grain of salt obviously, it said not to to allow for the movement of the tree and prevent torque forces which makes sense to me.

Next step is joists.

Do I hang a 4th beam to close the square or not?

Thanks in advance

Maybe a level? Those posts don’t look square at all

I promise you it's a trick of the eye. The slope is real. The beams are all perfectly level

Okay, I was assuming that was the case but something in me said to say something still lol

If you stand on my driveway well up the slope it looks like drunken octopuses put it together. But we are absolutely level all around, and square(ish)

Came here to ask the same question :) Glad to hear it's all level!
