I am located in South Australia. I have a small river front property that I would like to construct a tree house on. I would love some advice and feedback on the following points!
Being in Australia, I am limited to trees as our main eucalyptus trees have a dangerous tendency to drop limbs in the summer if they are stressed.
I have one poplar tree that is huge! The trunk is very thick and the tree is probably 30+ metres in height. At approximately 15 metres high there is a nice even three way split in the branches that creates a natural landing and what looks to me like a great spot to build a very basic treehouse. It would likely be mainly just a floor I would build perhaps with a very basic shelter to come later in the project.
I am thinking the size of the floor would be about 4x3m using all three branches as the supports. I could add some quick drawings of what I have in mind that gives an idea of the tree I'm dealing with but can't see an option here to do so. I could also build below these three branches using the 'outpost' design I have seen on this site.
I am unsure about the suitability of the tree, while it looks incredibly stable and is giant, it is situated at the top of a bank of the river and has the slightest of leans towards the slope. I imagine that the small nature of my construction wouldn't be a huge change to the balance of the tree though but would appreciate advice.
I am also interested in the best way to create access to the treehouse from the ground, given the height of the spot I want to build I imagine I will have to be efficient and clever to not blow out my small budget.
I am wondering whether given I have a three pronged tree whether braces underneath will be necessary. This design is similar to the 'outpost' concept except that it has the three prongs on the tree. I see in many of these designs that the braces are used but I wonder if having the extra support of those three braces would be enough. Also, I cant seem to find much information on how the lower end of the braces are actually connected to the base of the tree. I have seen designs with metal rings around the tree that the braces connect to but wonder if this would ringbark the tree.
I am very interested in anyones advice!
