apartment therapy changing the world, one room at a time

The good news first: your compound of adobe buildings is made of one of the most venerable, inert, and unquestionably natural building materials: mud.
Once mud is crafted into adobe, though, it demands expert advice. For information on adobe itself, we recommend without hesitation Preservation of Historic Buildings, published by the National Park Service, which publishes a slew of such briefs on other topics that your project will certainly touch on, like roofing.
So we'd start there, and then read everything else you can find about adobe; then you'll know if which consultants you find (and we'd recommend an architect who belongs to the USGBC for a project of this scope) is knowledgeable... or not. Tread carefully.
OK, so now you're an expert, or at least you know a thing or two. What next? We'd throw a party! Invite all your new neighbors, pour some drinks, and ask for stories about architects, consultants, and contractors... people are sure to come if you promise to circulate a list of sources after.
