Oregonconversion,
We like and welcome alternative ideas on TBN, with a plan. It seems like the plan is forming right now, so if you post some simple plot plans, a view of the property and slopes in question and your intended siteing of the container/house and garage that would be great.
You don't always get what you are looking for here, but if you post a plan, that will stimulate a lot of good ideas and suggestions as you go thru this process.
Take a look at "building a house in 90 days" thread, and obed's "home in the woods" posts and you will see a lot of engaged TBNer's offering great advise and insight.
We welcome you and look forward to seeing your plans.
Carl
