I am on the Board of Directors of an organization in Missoula, Montana named the Missoula Urban Demonstration (MUD) Project www.mudproject.org. We are contemplating a project at our demonstration site that will ultimately provide housing, but will also be an example of innovative, sustainable material conscious construction techniques. This will be a hands-on, community effort project. Our hopes are to have this project become a collaboration of the several non-profit organizations in Missoula that have this sort of vision.
I'm sending this after browsing your website and seeing many appropriate elements that we want incorporated into this project. The structure / structures will most likely be post and beam strawbale and cob construction. Much of this is general information and will be a great demonstration project. Where innovation can enter the project is in its foundation system and also its water use.
I have yet to find a foundation system that is effective as well as something that could be considered truly sustainable. Any direction would be helpful. One direction I went was in looking at gabion walls for a system. Is there a way of making this effective for a 2 to 3 level structure?
Also, we desire to develop a gray-water, composting toilet system. This is an area that I am now researching. If you are aware of any systems that have been approved by a municipality I would appreciate learning about it.
Any other suggestions/recommendations would be greatly appreciated.
