I don't know if I'd live in a house designed by him (although the author of this article seemed to love it). Might be too minimalistic -- thinking of the Kunsthaus in Bregenz for example. Of course this cabin is made of wood, not concrete. But in terms of a house that feels like a home, I'd go with Alvar Aalto; his designs ooze cozyness in a way that Zumthor's don't, and for a famous architect, they feel surprisingly pragmatic and sensible :)
