If you were a biodynamic farmer and wanted to build an eco house then using stawbales would suit very well.
Why use big bales? Peter says….
“I want the bales to be load bearing to support the roof rather than having a wooden structure with straw bale infill. This can be done with small bales, but it felt like it would be much stronger and quicker with large bales, as well as better insulated. There is an extra cost for the width of the foundations and roof, which is the downside.The bales could easily support two or three stories and it would have been more economical to build such a house – next time!”
