Beautiful Strawbale earth plastered demonstration building on the grouds of the US Botanical Gardens in Washington DC

Builders Without Borders has created an exhibit on the grounds of the US Botanical Garden in Washington D.C. as a showcase for natural building. In addition to the small one room structure a hardened adobe arch frames a view of the Capitol. Lime plaster, cotton roof insulation, a standing seam metal roof, a truth window and a bamboo trellis are all featured.
