A design and build project making a low-impact, mobile, ‘tiny home’ to fit planning law for 'permitted development' as 'seasonal agricultural and forestry workers, temporary accommodation. This design prototype will be 'open source' published with costings, materials lists etc. This design will be particularly useful for for any grass roots educational projects establishing themselves in the pre planning application stage. It would also be legal as a dwelling during any permanent residential build. We hope to build a few of these over the years to come to house volunteers on our Community Building Camps.
