John Annesley chose earthbags to build the walls for his large shop in the Arizona desert because they will never rot, burn, harbor mold or off-gass noxious chemicals. Additionally they provide good thermal mass for the fly-wheel effect that works so well in this climate. He plastered the walls with a combination of paper fiber, adobe soil and lime. He welded rebar arched roof trusses that support mesh for a ferrocement roof.
The story of why and how he built this structure is now available to see at earthbagbuilding.com.
