The next step is to build a house there. Right now this is close to what I have in mind: (look here for more specs)
This is a plan for a house made of straw bales. We are going to build with earthbags, though, as the materials are cheaper and more available, and it's easier to do round shapes with earthbags as they are stronger and don't require the buttressing that straight walls do. The half of the house with a larger radius (of 18 feet) is two feet longer than the recommended radius for an earthbag roundhouse, unless you buttress, but the inner walls will provide some buttressing so we might be able to get away with just putting in a couple on the outside. I am thinking of making those buttresses into life-size animal sculptures made out of earth. Like an alligator, for one of them, or perhaps a seated camel.
Building round and small is ecological because it won't require post and beam construction, thus using much less wood...and requiring less skill in the builders (I'm going to be one of them!). Round is harder to furnish, of course, but I think creative solutions can be found for this. The only problem I see with this model is I don't know where we would put the fireplace. We could try to do some kind of solar-powered radiant floor heating, but I think that would be very expensive and complicated.
We also would build an additional small studio roundhouse for guests to stay in, as well as for me to work in--both writing and hopefully Rolfing again--and generally as a place for me to get away from my husband's television addiction.
