I have three small birch trees, that I am trying to build a platform on. I'd like the platform to be about 1.8 metres high, and should take a small hut and a couple of people.
I've already build a 2x2.3m platform, which is suspended from the tree by ropes. I'm struggling to come up with how to fix it permanently. I feel like the design should involve some coach screws, and some steel wire, but beyond that I am a bit lost. Does anybody have any suggestions or advice?
I've attached a drawing of one idea that I had, and a picture of how the project looks at the moment.
