You want to exclude non-experts from this thread? Fine, but you can't extend that elitism to aesthetic judgements about housing design in general. We've all got skin in that game.
Forget the egg. All I'm saying is I may be in the market for such a house, and I do live in houses, so my aesthetic and 'liveability' responses are valid. I'm not responding as an architect. So if the place looks and feels like an underground carpark to me, who's to deny it?
