Well, both of you guys are more kind than a friend who saw it in person and told me that it looks like a strip shopping mall.
This is definitely a case of function over form. My wife took some convincing, but came on board with the idea when she recognized the benefits of efficiency, low maintenance and low operating costs as we get older. A side benefit is that yeah, it's pretty much a big tornado/bomb shelter also. Perhaps there is a subconscious remaining fear of the cold war from my childhood? A shrink could probably have a field day with this.
If the mrs. had her way, it would definitely lean towards the Palazzo Ducale end of the spectrum, but she's actually pretty practical and thrifty about most most things. If we spend any real money on it, it will be for a nice kitchen for her. I personally really like the idea of disappearing into the landscape. To that end, I hope to use native stone (or at least native colored stone) to put on as a facade. But you never know when you might have to repel a blitzkrieg or an allied invasion.
