Has anyone seen Cobb/Rammed Earth Housing?
I think that is what I want to do! If I build it into a hillside I can use the earth for the walls and I'll have excellent insulation.

I'm a fan of rammed earth or compressed earth bricks. Haven't seen much of anything regarding cobb housing. Cordwood is pretty cool in my book too.

I like cordwood too- but I think I want to do cobb for artistic reasons. I think nesting the house against a hill would lend itself to something I could shape artistically.

That reminds me of some articles i read about houses built into hills themselves not just the hillside...someone had essentially a 40*60 building that they pushed dirt up on the sides and top and then covered it in grass seed. It had a rainwater collection system, solar panels and skylights and the only external maintenance they had to do was mow the roof lol.

I'm more into function that appearances but houses built up against or inside of hills are always cool to me.

The only problem with cobb built into a hillside, where I live, would be too much rain perking through the rock. The rock can handle it just fine, but the cobb can't. Same problem with rammed earth or adobe here, unless you add a significant amount of cement or elastomeric powder into the mix---and the stucco on the walls of strawbales? Same problem! Sufficient waterproofing just makes everything too airtight for me, stuffy and stale. Earth plasters allow transpiration the best, but have to have quite a lot of protection, as in overhang or porches, which have to be overbuilt to accomodate the wind! That's the southern plains for you! I have seen concrete houses do quite well here, through all the different types of weather (and fires) that we have, and they're very quiet, much like my grandparents' stone bungalow was. You could never hear the wind in that house, which was nice for some people....but I like to hear the wind. It sings.

I have been researching all these alternative building systems since the '70s, and have tons of plans drawn up that I'll probably never use, unless I leave the plains. That would be really difficult to do.

This is the same concept and argument for high density housing, from a strictly energy point of view. By being surrounded, you share heat (and air conditioning) and have less points of exposure to the elements.

Something like Cobb housing works from an urban planning perspective of something that works as low density housing,

I really like Earthships, the houses famous in Taos, New Mexico. I'd love to live in one, but I don't think I live in an area that would currently support it. We shall see, however, we shall see!

I think I have a working floor plan!
