I admire home builders. (My latest case is 84 years old man is building his farm house by hand.) Birds have ‘cultural’ (or genetic) plans to build their nests. Wild pigs also build nurseries for their newborns (with leaves and branches) and so many other animals. Human tops the list of design, innovation and use of materials. 👍️

I wonder if your plan should be overlaid with electrical wiring, water plumbing, waste water disposal, air/heat flows, … (I see 2 septic tanks - but no sinks, no basins, no showers, no kitchen, no fire/emergency exits, and no rain water catchment/tank.) I think incorporating these considerations can make much safer, more energy efficient, more comfortable and more distinct homes.
