Looking for feedback/instruction for treehouse supports

Hello all, i’m looking for some feedback on this treehouse, specifically the ground supports/pillars. This build will be at a rental house so it cannot be connected to the tree.

I was trying to have the supports be visually interesting but I also want it to be super sturdy. Not an engineer so I may have overdone it in some places. Feel free to let me know.

Open to suggestions and feedback on the model in general, not just the pillars. Tia

I call it brick outhouse engineering. :smiley:

Are you going to put the posts in the ground? If so, how far and will there be footings?

I might consider creating X’s with the bracing. I’d probably also reduce the number of short pieces between the joists.

Maybe something like this?

Thinking about your framework a bit more. Trying to eliminate the hanging joists.

Turn the ladder 90° so it comes up between two joists?


Really great feedback. Thank you Dave

You’re quite welcome. Might not be worth even what you paid for it. :smiley: Maybe it’ll give you some ideas though.

I would offer a couple suggestions in addition to @DaveR s. I like the beams to have at least 1 1/2" bearing on the posts instead of shear fastening. Also, seems like a slightly squarer cut on the double beam would be a bit stronger.

Probably overkill but I’d go around the tree trunk something like below.
