I see at least two main approaches to building a pit house with earthbags:
1. Mimic Mike Oehler’s greenhouse design using earthbags instead of poles and shoring.
2. Mimic conventional walipini pit greenhouses. That’s what I’ve chosen to do in the following drawing. It’s very similar to typical walipini’s, so follow the directions in the link. Which one is best? It would be good to build both designs and measure their performance to see how they compare.

Note: high quality greenhouse plastic film is recommended, not ordinary plastic sheeting.
