>>1252087Yes, in a typical home you'd want to run it to the very top to the corner though, they call them braces, because they take shear loads (sideways) to the wall. it's like a soccer goal that prevents it to tip over. If the roof was heavier though, you'd want it higher up so it doesn't snap the stud in half like a twig.
In a timber framed home, the first thing laid down is a foundation. The side walls are constructed laid down and erected on the concrete and tied together with nails, brackets, or joints carved into the wood depending on the strength needed.
Since you don't have a conventional concrete foundation, cladding for walls, or insulation, you can take lots of creative liberties on how you go about flooring, walls, and roofing. You have a a whole bunch of branches around your site that you can lash up to some pallet studs and then weave some grass in the gaps. If you are pitching a roof, you can make one wall half as tall as the front so you can walk inside, and just find the length of the diagonal by taking the square root of the height of the front wall minus the height of the back wall squared, plus the length between the two walls.
Doesn't have to be completely waterproof because the rain will run down whatever you thatch it with to the back.
