hacking cabin construction

Let's say I want to build a small very cheap off grid cabin* and am reasonably intelligent, if ignorant in the ways of construction. I have access to land already and a large building near the construction site that can house material and tools securely. Are there smarter ways to construct a small off the grid cabin quickly as a single adult? Is anyone developing/writing about/coming up with smarter ways to quickly build a small cabin? Has this been, for lack of a better word, "hacked?"

*small = ideally, twelve feet by twelve, a second floor or secure roof access, and no real need for electricity or plumbing.
