Cuevas de Sol
A well documented studio Earthship in Spain - the first I've seen with partial earth walls with tires added only above ground.
Nice images of cob / earthbag / strawbale construction in what looks like a desert landscape.
Dan Nogal’s Earthship
A small studio sized Earthship built by the Biotecture crew with interns. Lightly documented though images are always useful :)
Oscar & Lisa’s Eartship Build
A very nice small-family sized Earthship build in Spain built by a charming couple.
A documented Earthship build from the USA – including some lessons learned in retrospect.
Es Cargo Earthship
Nice documentation with images of a small two-level Earthship in Canada - including good documentation of a Rocket Stove build.
A good blog including the story of a self-build family-sized Earthship taking place in Canada.
Off The Grid Build
Excellent video and images describing the process of an Earthship construction project.
Build It Solar
A must read/visit/try/build/share website for ecologically aware do-it-yourselfers. The only shortcoming is the name because there is much more then "solar" in it.
Metal parts and fasteners - located in the industrial area of Cluj.
