We developed techniques to build a 700 square foot, expandable starter home - loaded with ecological features - in 5 days - for $25k in materials. Now we want to make the open source eco-building toolkit required to do this - available to the rest of the world.
This toolkit includes modular designs, plans for utilities and appliances, construction machine designs, materials recipes, and training programs—everything you need to design and build a house. The OBI toolkit is entirely open source and free to use. We've been developing and testing it for a few years and already have a lot of work in place, but there is much more to do. We are coming to you for help to make it accessible to everyone.
