The 'earth-covered buildings' by Peter Vetsch, often called 'cave buildings', belong to the most individual and, at the same time, most simple and clear contemporary buildings. Vetsch dissolves the straight line and angular carpentry architecture for the sake of the soft and curvy line, and forms caves and housings therein. The dissolution of old forms enables the shift to deeply unconscious, archaic existential sensations. The boundaries Peter Vetsch crosses are simultaneously the boundaries of the unconscious.
