Modern church like? I could see that. I also see this instance as a somewhat extreme version of FLW signature features: low slung angled flat roof, wide roof overhangs, ground to ceiling exterior glass, custom and built-in furnishings that sort of lock the inhabitants into a certain way of living.
It's sort of a love it, or hate it, or be indifferent thing... and anyone who buys it should have already decided they love it.
Not that the FLW vision of how people should live is a bad thing. It just might not be for everyone.
I probably could live in one of these, but it would take some adjustment and lifestyle changes. The full basement is an attractive feature: a place where a washer collection could go, or all that junk you don't want on display upstairs <g>
