“Poula-Line built her straw bale home in Fri & Fro (Free and Happy) ecoVillage in Egebjerg, Denmark. It’s one of a collection of unique straw bale homes in the village. Her home was inspired by a conch shell she found on a beach in Malaysia. Poula, just like Rachel, lived in a small straw bale cabin on her land while she built her home.”

$100 Cabin made of Black Locust and an Old Billboard for the Roof

“See an example of a cabin made from black locust wood and an old billboard that is around 300 sq. ft. and costs right around $100 to make. This cabin will be a great three season home or can be insulated later with straw bales to make a comfortable place to live. All resources sourced locally for minimal gas use to get them. The main cost is in the Black Locust ‘slabwood’ from a local mill (waste, or offcuts of wood) at $75 in total for three $25 truck loads, and ~$25 in high quality #2 square driven PGP screws (2.5″ mainly, and some 1.25″ for roof battons and side wall batton fastening.)”

High Tunnel Greenhouse Construction


A polytunnel (hoop) greenhouse like this would be faster and easier to build than a dome. This particular polytunnel design is low cost, strong and easy to build.
