I’ve been very interested in underground dome homes with living roofs for many years after my dome building Instructable went viral. The other day I was watching a video about Hacking Aircrete that showed the dome home featured here. One side has a geodesic greenhouse and the other has a skylight.

Below Grade Earthbag Domes
Email from a reader: Hello, I am trying to put together a design for an earthbag dome built into a hill in New York, and for a few reasons, I would like to have some of it underground. Actually, there are two adjacent domes, one with a diameter and height of 14′, and the other 8′. The frost line here is at least 48″, and I’ll probably go down further.
