Working from memory of feelings of spaces, Zumthor would inherently create more sensual spaces, designed for the entire being as one. However I believe the occasionally ambiguous and idiosyncratic spaces he creates have the ability to appeal to parts of our psyche that explicit buildings do not.

Reasoning- Ambiguous shapes and implicit forms; architecture, which is less explicit, leaves room for the imagination. Something, which is definite, leaves no room for memories or personal responses to a buildings presence.  As one of the greatest tools with which we can articulate our existential being in the world, architecture should leave lots to the imagination. Spaces can be filled with our memories when aspects of a building are kept a secret. I believe Zumthor achieves this in his creation of specific atmospheres.
