Guys Ive been tasked to build a tree house for the ankle biters. Not that I don't have enough to do already; but Im thinking that a basic tree house without all the bells and whistles shouldn't be too much of a chore.
Im thinking that it will effectively be a 4x6 shed on stilts with a bit of a veranda type affair and a set of steps.
I think im happy with the framing side of things mostly 4x2, and the basic construction etc but two elements are unclear in my mind and any guidance would be appreciated.
Firstly - the supports. It wont be supported by trees, albeit it will be amongst the trees they are not suitable to use as supports. So that leaves me with how to set the legs in/on the ground. I will be using pressure treated 2x6. So set them in concrete, or on top of set concrete? Or another method? A limited amount of research suggests both may cause swift rotting due to continual damp.
I was going to bolt two together to form the supports, with one cut at platform height to work as a sort of trimmer stud, with a sole plate running between the two supports. The longer one would continue to roof plate height to support the roof.
So this leaves me with how to join the two sides together.
Any pointers on how to construct the support framing very much appreciated.
