Economic, yes, ecological yes. But I grew up in a (wooden) house insulated with straw and mud. And it does have mildew and damp issues (and rats). Then again, I survived and miss the old house, and the world moves on - so if you live in a drier place than I and with your consideration into the construction, maybe it could work. And - your design is really very nice. Wish you the best of luck with your dreams of the house. Sure you will pull it off - with lots of modifications along the way - but that is part of the fun...
Thanks for sharing. ok
