natural building materials
:: locally available - what does each property offer?    cow manure, straw, sedge, cattails, round poles (straight trees of reasonable diameter and height for harvest)
local materials specifically adapted to local climate (inherent weather resistance, durability)
:: sustainable - minimally processed, low energy use for harvest or production, minimal consequence
of acquisition, little to no transport, rapid renewal, small scale harvest minimal impact on habitat,
ability to recycle, reuse, repurpose;  repairs / remodel generate minimal waste
:: building design based on sun observation
ex. face living roof towards south
