Well, if I was stranded in a pine forest and figured to be snowed in for the winter, I'd fashion it out of pine. But first, I would try to avoid being stranded in a pine forest to begin with.
Now if I was going to fashion a line shack in the back pasture, I'd use treated 4x4's for the base covered with 1/2" waffle board floor. Frame it out of 2x4's and sheet it with 7/16" waffleboard. Roof would be 2x4 trusses for rafters, sheeted waffle board, covered with roofing felt, covered by corrugated metal. Sides would be finished with any suitable siding I could find including old barn wood. A simple sheepherder stove and comfort would be assured.
