No, I don't have an architect or engineer involved. My educational background starts with mechanical drafting (including architecture) then ramps up to manufacturing technology with emphasis on materials and systems. I've been doing specific research for several years. All the bits and pieces have been thrown into my mental cauldron and are melding together. I think the resulting stew is finally ready to be realized in our future home.
Why earth bags rather than tires? Several reasons, in some sort of order ...
I'm not as young as I used to be. Hauling a 50# bag of earth will be easier on my back than all the ramming that tires would require.
A source for new bags has them available for less than 20 cents each. Bags don't take much room to store when they are empty.
I think it will be easier to
sell the
local office that has to sign off on my house plans. A healthy ratio of cement in the bags
should be the winning argument.
There are various sites available that have architect approved plans for earthbag homes, in the event that I need them.
Earthbags will allow me / us to use a modular approach that can be enlarged as necessary. Since this will be home to an extended family dynamic and only one house is allowed on the property, that versatility is important.
Oh yeah, there is also the "build as you can afford it" element.
