The roof of the home is totally load bearing on the cob walls.
The house is 600 sq.ft (56m2) on 2
floors and cost about $56,000 (£35,000) to build. Pat's ultimate goal is to build a '10 Mile House',
where every material required for the construction of a home comes
from within 10 miles of the building plot. Few natural buildings
use entirely local materials but here are a few: Ben Law's
roundwood cottage, James O’Keefe's
oak playhouse, Michael Buck's
cob cottage in England and Menthe Mawaw's tiny
woodland cottage in France.
