Not a "shouse". It's termed a hybrid cob/straw bale house. Here's a video link that shows a similar construction:
https://www.youtube.com/watch?v=rL7HDA2sPS4&list=PLxJa2E7AZDHn_l-dCoc230MRU5B8Vz3yC&index=12Our design is different as it has a crawl space instead of a concrete slab. When finished, it will have 3 post frame rings. The 6x6 post frame you see in the picture, the next will be a 4x4 post frame on the deck that supports the straw bale stack along with the door & window bucks. The 3rd will be another 6x6 post frame for the wrap-around porch roof.
Once the straw bales are stacked, they will be coated inside and out with about 3" of cob (mixture of sand, clay, and straw) making the walls about 2 feet thick. According to my research, we should end up with breathable walls with an R-40+ insulation value. The crawl space was poured using ICF blocks that also tout an R-40 insulation value and a radiant heating system in the floor.
If all goes as planned, we should end up with a very strong, fairly cheap, extremely energy efficient house.
Shawn, post frame homes are not common here, although there are a few houses built fairly recently that are basically framed in pole barn style.
