Frame of oak thinnings
There is a naturally cooled refrigerator in the house. It is cooled by air coming underground through foundations. The house residents use water from the nearby spring. Solar panels generate electricity for lighting, computing and music. Day light penetrates through the skylight in the roof of the house.
not much of your reply makes sense to me. most homes are made with treated wood and non-wood layers which greatly help to keep out rot, weather damage & boring insects. but the house above, although beautiful, is not far from being a potential compost heap. natural pest control methods would only delay slightly the composting situation, not prevent it.
this house is not like 'green roofs' built on reinforced and tarred urban roofs, like NYC. no, when the roof becomes a problem they will pretty-much need to tear the whole house apart & rebuild. early man built houses for at least tens of thousands of years and there's a reason they did not build like this. this is a case of perfectionism & over-ambition IMO.
