I forgotten to mention the most important issues I face.
The property on which I hope to build has High-tension power lines very close by (within ~250 ft).
I understand that living near those can pose health issues, Leukemia for example.
I was thinking that perhaps an underground building such as a wafati or something similar in which a massive amount of earth was utilized, would help shield off/negate the effects of electro pollution.
So now I'm thinking that an above ground building might not be a healthy option?
Besides with a rocket mass heater, does it really matter all that much what construction method is utilized?
I recently saw a video here on Permies explaining how a rocket mass heater did a decent job in a canvas Tipi in sub-freezing weather!!!
