... I think the newer designs have corrected a lot of those issues, and they should be much sturdier structures...
...I think in any event, they are probably as well build, if not better built than traditional stick built houses...
I think a well ventilated straw bale houses with a metal roof, as I am planning on using, are going to be about as long lived as one could possibly get without building out of stone. If I am understanding what you are saying, it sounds like you think strawbale houses have more moisture degradation issues than other houses.
I am not sure why I would want to reduce the amount of glazing. Bill suggested reducing the glazing surfaces to just one, but not necessarily the amount of glazing. In tandem with your final suggestion, it sounds like you think having the attached greenhouse is problematic... Since the attached greenhouse is kind of fundamental to this design, separating it would seem to destroy most of its functionality. Is there a reason you think this should be done?
What does a metric clock look like? I bet it is nothing like this tiny ad:
