TW, I would be building in Nova Scotia, Canada. I don't plan to build it anytime too soon. It would be once my wife and I decide on building a house. Thinking about the range of 5 to 7 years or so.

Bahler, That is great that is it a sound building method. I am looking for who I should be talking with to discuss my idea of the building to. To see if what I have in mind is possible and what would be necessary for this to be built.
