Top links to share w/ someone open to earth integrated housing?

If someone was planning on building a ~2500 square foot house in rural Virginia and was interested in the potential cost savings of earth integrated housing, what links/sources would you give them? Or who would you point them towards for consultation/questions?

Thanks for any help!

Here are the links I would share:

Thanks very much! Does anyone know what kind of work would be necessary in getting a design drawn up and how to work with/around building codes?

For example, if I sent an architect those three links, is it the sort of thing where they could work work out a design that's up to VA code without too much trouble? Or would it be the wild west and require lots of back and forth with the state?

Pardon my ignorance if these are obvious questions, just doing my best to spread earth integrated housing =)

I may be way off though I doubt that an architect would even consider drawing up plans for those structure.

What you might be able to get an architect to design would be a traditional home with an earth berm.

I have never tried this though at one point in my life I had friends who were serious looking for land to do this. I lost touch with them so I don't know if they fulfilled their dream

You might share this link with an architect:

Thanks again, another question if I may:

Is there a general size constraint on WOFATIs? Looks like the ones in existence are between a cabin and small house.

I watched some of Mike Oehler's DVDs forever ago and iirc his designs could be extended to cover large square footages (though not usually multiple floors?), not sure if that translates to WOFATIs with the berm.

You might try finding plans for a house with a basement.  Make it a walk out basement.  There are house plans try southern living, the library, ask around for local builders and talk with them.  They often have house plans they use and reuse.  I live in NC and people around do not do basements.  I love basements!!  Trying to figure out what I will do.  Good luck!!
