Looking for recommendations on sustainable/alternative homebuilders/contractors. My partner and I just bought land outside of Madison and are looking to build a house. We want a small(~1000 square feet) earth sheltered home and we are wanting to incorporate passive solar. We would love to find someone that works with cob, rammed earth or compressed earth blocks. Any help is greatly appreciated!

[Design Coalition](http://www.designcoalition.org/) can help with design, they might have recommendations for builders. [Loren Imhoff](https://lorenimhoff.com/) built our traditionally-built passive solar home and incorporated all the "green" stuff we wanted (solar hot water, solar electric, geothermal, etc.). Don't know if Loren has ever done earthen homes, but he was open to non-traditional stuff like insulated concrete forms.

I work for a Madison area General Contractor, if you end up looking at more 'traditional' super insulated construction (double stud wall, dense pack cellulose, focus on air-sealing, etc) please feel free to reach out. I don't have experience with cob/rammed earth. If you pick up any used books on passive solar, a lot of the older ones (1960-1980's) have designs that typically overheat the house. It's a tricky balance and having an energy model done is a good way of finding some obvious flaws that aren't obvious when you are just looking at a design in a printed book. Perhaps Design Coalition would have some ideas: http://www.designcoalition.org/
