Thanks for all the help, and the advice about obsolescence. Financing is not a problem, and at this point in life I am not real concerned about resale. I actually think the finished design will be attractive and functional, but obviously one man's opinion. I designed it for me, hence the small second floor, with the idea of being able to add 2 bedrooms on the living room end for larger families before selling it. The upstairs is the master BR, study, watch the sunrise play off the back of Mt. Rainier in the morning (it's due east of the building site with an unobstructed view) in a fairly rural setting.
Yes, when I posted I thought it said clearly that this was the Home Designer forum, but obviously was mistaken and I apologize. I'll re-post to the appropriate forum with the plan file.
